The bonus percentage is only one part of the calculation; eligibility, game contributions and withdrawal conditions also affect its value.

What a 600% Headline Leaves Out

A 600% welcome bonus sounds like a cash amount. It is not. It is a rate applied to a qualifying deposit, and the rate may describe only one part of a wider package. The figure on the banner is therefore a starting point for the calculation, not the result.

A 600% deposit bonus means that the bonus component is linked to six times the qualifying deposit, subject to the stated maximum and the operator’s conditions. The deposit itself is not a bonus. Nor does the percentage establish how much can be withdrawn, how long the funds remain available, or which games will count towards any release requirement. Those details determine the practical value.

A specialist review of these offers identifies six variables that need to be read together:

• the reward attached to the promotion;
• eligibility for the welcome offer;
• the qualifying deposit;
• the contribution made by each game;
• the expiry period;
• the withdrawal conditions.

Changing any one of them changes the calculation. A large percentage attached to a small qualifying deposit may produce less bonus credit than a lower percentage attached to a larger deposit. A high stated maximum may also be irrelevant if the deposit needed to reach it is outside the intended budget. The label alone cannot show that distinction.

Percentage is not immediate value

The first question is what the percentage is applied to. If the promotion is a straightforward match, the bonus is calculated from the qualifying deposit up to the advertised ceiling. If the offer is split into stages, the headline may combine several separate rewards rather than describe the amount available after the first deposit.

That structure matters. An offshore welcome package can be arranged across several deposit stages and present a total stated value exceeding £5,000, according to a specialist review. Such a figure may look like a single 600% casino bonus, while the terms actually divide it between an initial match, later deposits and additional promotional elements. Each stage can have its own qualifying conditions and its own deadline.

The total is therefore a package value, not necessarily an immediately available balance. Reaching the advertised total may require several deposits, each made under the relevant terms. Counting the full headline before those deposits are made treats a future possibility as present money. Accounts are not generally improved by optimistic arithmetic.

The qualifying deposit sets the starting point

The qualifying deposit is the base on which the match is calculated. It may be necessary to deposit a particular amount, use an eligible deposit method and claim the relevant welcome offer before the bonus is added. Those access mechanics are separate from the value assessment, but they decide whether the percentage can be used at all.

Bonuses: UK Casino Offers and Free Spins

Eligibility also narrows the headline. The welcome offer is intended for new customers, and a promotion may be restricted to one account or one household. A person who does not satisfy those conditions cannot treat the advertised percentage as an available entitlement. The same applies where the deposit does not meet the promotion’s definition of a qualifying deposit.

The sensible calculation begins with the amount that can actually be deposited under the applicable terms, not with the largest number printed in the advert. The result should then be recorded as bonus funds rather than cash available for withdrawal.

Game contribution changes the cost of the offer

A bonus balance may be displayed in an account, but that does not make it equivalent to withdrawable funds. The games used to clear the relevant conditions can count at different rates. Slots usually contribute the full stake towards wagering, while table games can contribute only a fraction and live dealer games may contribute nothing. A 600% slots bonus can therefore be materially different from the same percentage attached to a mixed casino offer.

This is not a minor wording issue. If a chosen game contributes only part of a stake, more total play is needed to produce the same qualifying progress. If it contributes nothing, the stake does not advance the relevant balance at all. The headline percentage remains unchanged while the route to withdrawal becomes longer or narrower.

The game category also matters because a promotion may exclude particular titles or limit which stakes qualify. A banner that uses broad casino language should not be treated as proof that every game contributes on the same basis. The contribution table in the terms has financial significance.

Expiry and withdrawal rules finish the calculation

Time is another part of the value. Bonus funds and free spins can expire after a set period, with periods from 7 to 30 days identified in specialist promotional reviews. An attractive balance that expires before the conditions are completed has no cash value at the point of expiry. The deadline should be considered alongside the available game contribution and the amount of play required.

Withdrawal rules can reduce the result further. The terms may require the deposit to be played through, require identity checks, restrict the deposit method used for withdrawal, or impose a limit on what can be taken from a spin-based reward. A percentage cannot answer any of those questions.

There is also a legal separation between British-licensed casinos and offshore operators. Remote operators selling into the British market must hold a UK Gambling Commission licence. Offshore casinos operate outside that UKGC system and do not hold a UKGC licence, even when their welcome package is freely accessible to British residents. A large advertised total is not evidence of British licensing, consumer protections or compliance with British bonus rules.

The correct reading of an online casino with 600% bonus in 2026 is therefore conditional: identify the reward, establish the qualifying deposit, confirm eligibility, inspect game contribution, note the expiry and calculate the withdrawal result. Until those elements are attached to the percentage, “600%” is packaging rather than a final amount.

The First Deposit: When the Bonus and Spins Are Credited

A 600% first deposit casino bonus is not claimed merely by opening an account. The offer becomes relevant only when the required sequence has been completed: registration, opting in and making a qualifying deposit. The order matters because an account can exist without the welcome bonus being activated, and a deposit can be made without producing the advertised reward if the offer was not selected.

Online casino with Bonus Crab: UK offer terms

Registration creates the customer account. For a UK-facing operator, age must be verified before funds can be deposited. A current UK Gambling Commission licence is also required for an online casino legally serving British customers. These are not decorative checks. Until the account and age-verification process are accepted, the deposit stage cannot be treated as a completed claim.

The next step is opting in. This records that the customer wants the welcome offer attached to the account rather than leaving the account on its standard terms. The opt-in may appear as a tick box, an offer selector or another confirmation within the account. The important point is the recorded choice, not the appearance of the button. A large offer displayed on a landing page has no value if the account has not been connected to it.

The deposit then has to satisfy the offer conditions. That means the amount and timing must meet the qualifying-deposit requirement stated in the terms. A deposit made before opting in may not be treated in the same way as one made after the offer has been selected. The same applies where a customer deposits funds but does not complete the required activation step. The money can be in the account while the welcome reward remains absent.

Online Casino with a 200% Bonus: How It Works

This is the point at which a phrase such as “600% deposit bonus” needs to be read as a conditional instruction, not as an automatic multiplication of the first payment. The headline identifies the promotional package. The account records whether the package was selected, whether the deposit qualifies and whether any further action is outstanding. The amount displayed as bonus funds is therefore a result of the operator’s checks, not proof that every part of the offer has been delivered.

Free spins can follow a separate crediting trigger. A specialist review notes that some welcome offers require a qualifying stake before the spins are added. In that structure, registration, opt-in and deposit do not complete the spin claim by themselves. The customer must first place the qualifying stake specified by the offer. Only after that condition is recognised can the free spins be credited.

That distinction is especially important where a package is described as a deposit bonus with free spins. The deposit-match element and the spin element may not arrive at the same point in the process. The bonus funds may be shown after the qualifying deposit, while the spins remain pending until the required stake has been recorded. Treating the entire package as one immediate credit creates the wrong expectation about the available balance.

An account can therefore pass through several stages:

1. Registration: the account is opened and the operator completes the required age checks.
2. Opt-in: the welcome offer is selected for that account.
3. Deposit: the qualifying deposit is made under the offer’s conditions.
4. Bonus review: the operator checks whether the deposit meets the promotion rules.
5. Spin trigger: where the terms require a qualifying stake, that stake is placed before the spins are credited.
6. Credit: the bonus or spins appear in the relevant promotional balance once the applicable condition has been met.

The sequence does not establish that the reward is cash available for withdrawal. It establishes only when the promotional funds or spins are placed in the account. Their later treatment depends on the terms attached to the offer, including the conditions governing play and withdrawal. Those are separate calculations from the act of claiming the welcome package.

For offers described as mobile casino promotions, the same distinction applies. Using a phone rather than a desktop computer does not turn a displayed promotion into an activated reward. The account still needs registration, opt-in and a qualifying deposit, and the free spins may still wait for the required stake. A mobile screen can make the process look compressed; the conditions remain separate.

The cleanest record is the account status immediately after each stage. If the offer is not shown as selected, the claim has not been established. If the deposit is present but the bonus is pending, the qualifying conditions have not yet been confirmed. If the bonus is visible but the spins are absent, the spin trigger may still be outstanding. That is a sequence of account events, not a single promise attached to a percentage.

Promo Codes, Eligibility and Payment Exclusions

A 600% casino bonus code is not a universal key. It is one condition in the welcome offer, and its effect depends on how the operator has configured registration, eligibility and the deposit method. A promotion can be described as available to UK players while still failing to apply to a particular account or transaction.

Do

• Enter the promotional code correctly during the deposit process
• Verify if the deposit method is accepted for the specific offer
• Check if the account is eligible as a new customer

Don’t

• Use an incorrect or omitted promotional code
• Assume an automatic offer applies to every deposit
• Use a deposit method that is excluded from the terms

The first distinction is between code-based and automatic offers. Some bonuses require a promotional code to be entered during the deposit process. If the code is omitted, entered incorrectly or added after the qualifying transaction, the system may record an ordinary deposit rather than an eligible one. The code field is therefore not decorative. It is part of the claim procedure where the offer terms make it mandatory.

Other welcome offers are applied automatically. In that structure, the account or deposit is matched by the operator’s system without a code being typed. That removes one possible input error, but it does not remove the other conditions. Automatic application does not mean that every new deposit qualifies, nor does it mean that an account is eligible simply because the promotion appears on a website or in a casino app.

The practical difference can be checked before depositing:

• whether the offer requires a promotional code;
• where the code must be entered;
• whether the code must be used during registration or at deposit;
• whether the promotion is automatic instead;
• whether the account has been identified as eligible;
• whether the selected deposit method is accepted for the offer.

A code intended for a welcome offer should not be treated as interchangeable with a general casino code. The operator may attach it to one promotion, one customer category or one particular deposit route. Entering a code associated with a different campaign can leave the transaction outside the advertised terms, even when the percentage looks identical.

New-customer and household restrictions

A specialist review of these offers identifies the central eligibility restriction as new-customer status. The welcome offer is intended for a newly opened customer relationship, not for an existing account that has never used a particular promotion. An account holder who has already registered may therefore fail the new-customer test even if no previous welcome bonus was claimed.

The same review describes a one-per-household condition. That restriction matters where more than one person shares an address, device, connection or other account details used by the operator for verification. A second registration is not automatically treated as a separate qualifying customer merely because it uses a different name or email address. The final decision rests with the operator’s eligibility checks and the published offer terms.

Online Casinos with Daily Promotions in the UK

Age verification is also a condition of operating a gambling account in Britain. Operators must verify that a customer is aged 18 or over before allowing a deposit. A promotion cannot bypass that control. Registration information, identity checks and the account details used for the deposit must remain consistent enough for the operator to confirm eligibility.

This is why an attractive 600% casino bonus offer for UK players should be assessed as an account-specific promotion, not as a general entitlement. The public wording may show the headline, but the account status determines whether the offer can actually be attached.

Deposit method exclusions

The deposit method can decide the result independently of the code. A specialist review notes that welcome deals may exclude particular methods, including e-wallets. Selecting an excluded wallet can therefore produce a successful deposit without producing an eligible bonus. The money movement and the promotion are separate records.

Attention
British gambling operators cannot accept credit-card payments for gambling, including those routed through money service businesses.

British gambling operators also cannot accept credit-card payments for gambling. That prohibition covers credit-card funding routed through a money service business. A wallet cannot be used for gambling where it permits credit-card funds to finance the transaction. Consequently, a payment route that appears available in a banking menu may still be unusable for a casino deposit or ineligible for a welcome offer.

The exclusion needs checking at the level of the actual funding source, not merely the brand of the wallet or payment service. A wallet funded from an accepted source is not the same arrangement as a wallet funded by credit. The operator’s terms and the deposit screen should agree before the transaction is made.

The same assessment applies whether the account is opened through a desktop site or a casino app. The application does not create a separate eligibility category. A code-based offer still requires the code where specified, an automatic offer still depends on the operator’s matching rules, and a restricted deposit method remains restricted.

The cleanest record is the confirmation shown before and after the deposit: the promotion name, code status, account eligibility and deposit method. If any one of those elements conflicts with the advertised welcome offer, the headline percentage has no practical value for that transaction.

Welcome Spins: What the Listed Offers Actually Include

The phrase “600% welcome bonus” suggests one large percentage applied to a qualifying deposit. The listed packages are structured differently. Their stated components consist mainly of free spins, with one fixed cash bonus and one percentage-based deposit match. Treating them as interchangeable would turn different rewards into one misleading headline.

A specialist review lists the following welcome packages:

LuckyMate: a fixed bonus plus spins

LuckyMate is listed with a £10 bonus alongside 50 free spins. This is the only package in the comparison that combines a stated cash-bonus amount with a stated spin allocation. The £10 figure is a fixed amount, not a percentage of the deposit, so it does not operate like a 600% first-deposit offer.

The 50 spins are a separate component of the package. They should therefore be recorded separately from the bonus amount when comparing the offer with a deposit match or a spin-only promotion. A spin count describes the number of game rounds attached to the promotion; it does not convert directly into a cash value.

BetWright Casino and Quickbet: identical spin counts

BetWright Casino and Quickbet are each listed with 100 free spins. Neither entry includes a separate cash-bonus amount or a deposit-match percentage in the listed package.

That makes the headline distinction straightforward: both are spin-based welcome offers, rather than a 600% real-money welcome bonus. The shared count does not establish that the offers are otherwise identical.

BetMGM Casino: the largest listed spin allocation

BetMGM Casino is listed with 200 free spins. By count, that is twice the allocation shown for BetWright Casino and Quickbet, and four times the 50 spins listed for LuckyMate. That is a comparison of quantity only; it does not turn the spins into a cash equivalent.

LuckyMate

£10 bonus and 50 free spins

BetWright & Quickbet

100 free spins

BetMGM Casino

200 free spins

Casumo

50% deposit match up to £100

It therefore belongs in the spin-led category, not alongside a percentage offer simply because both are described as welcome promotions.

Casumo: a percentage match rather than a spin package

Casumo is listed with a 50% deposit match up to £100. This is a deposit-based reward, not a stated free-spin allocation. The percentage applies to the match structure, while the cap sets the maximum bonus amount named in the offer. It is consequently the closest of these entries to the language of a first-deposit bonus, although its stated rate is 50%, not 600%.

Comparing it directly with 50, 100 or 200 spins would mix two different reward formats: a deposit match and a number of game rounds.

What the comparison shows

The five named packages divide into three forms:

1. Fixed bonus plus spins: LuckyMate, with £10 and 50 free spins.
2. Free spins only: BetWright Casino with 100, Quickbet with 100, and BetMGM Casino with 200.
3. Deposit match: Casumo, with a 50% match capped at £100.

A large-sounding “600% free spins welcome bonus” label can therefore conceal a basic difference in structure: the offer may be expressed as spins, a fixed bonus, or a percentage match. The figures must be read in their own units before any value comparison is attempted.

Wagering Requirements: The Stakes Behind the Bonus

A welcome bonus is not valued by its displayed percentage alone. The relevant figure is the amount that must pass through eligible games before the bonus balance can be released. A large deposit match can therefore create a much larger staking obligation than the promotional headline suggests.

For bonus funds offered under the Great Britain licensing regime, the wagering requirement cannot exceed 10 times the bonus amount. This is a ceiling on the multiple applied to the bonus, not a promise that every offer will use the full allowance. The terms still determine the applicable multiplier and whether it is calculated against the bonus alone or another defined amount. That distinction matters because a deposit match and the qualifying deposit are not interchangeable figures.

The calculation is straightforward when the terms use the bonus-only method. A £20 bonus at 10x requires £200 in total stakes:

£20 × 10 = £200

The £200 is the cumulative value of qualifying bets, not a required single wager and not a guaranteed loss. Bets can be won or lost while the wagering counter advances, subject to the operator’s rules. The balance available for withdrawal remains a separate question until the requirement has been completed and any other conditions have been met.

Game contribution changes the practical workload

The stated wagering figure assumes that every qualifying stake counts in full. Game contribution can make that assumption wrong. Slots usually contribute 100% towards wagering, so a £1 eligible slot stake would add £1 to the qualifying total. Live tables and blackjack may contribute less or nothing, meaning that the same cash volume can produce a smaller increase in progress.

Online Casino with 300% Bonus: How the Match Works

Other terms distinguish between different table games, live versions and specific titles. A contribution rate is applied to the stake rather than treating the whole game category as equally useful. If a game contributes only partially, more money must be staked to reach the same qualifying total. If it is excluded, play on that game does not reduce the outstanding requirement at all.

This is why a bonus with apparently modest playthrough can still require careful game selection. The headline multiplier is only one part of the calculation; the contribution percentage determines how efficiently each stake moves the account towards completion.

The deadline turns the total into a time problem

Wagering is also subject to an expiry period. A specialist review identifies periods from 7 to 30 days for meeting wagering requirements, but the binding period is the one stated in the individual offer terms. Once that period ends, any unfinished bonus requirement may no longer qualify for release.

The time limit changes the practical value of the promotion. A £200 qualifying total spread comfortably across the available period is a different obligation from the same £200 compressed into a much shorter window. The calculation remains £20 multiplied by 10, but the pace of qualifying play changes.

Account records should show the remaining bonus balance and wagering progress where the operator provides those controls. That information is more useful than the headline percentage: it shows the amount still outstanding, which games are counting, and whether the deadline is approaching. A 600% deposit bonus with free spins can look substantial, but its usable value depends on the bonus amount, the permitted multiplier, game contribution and the time allowed to complete the requirement.

Online casino with 400% bonus: terms explained

No-Deposit Spins: Winnings Are Not Automatically Withdrawable

A no-deposit welcome offer removes the need to fund the account before the spins are issued. It does not necessarily remove the conditions attached to the winnings. The important distinction is between receiving the spins and receiving cash that can be withdrawn.

The spins may be available at no cost, while any amount produced by them is placed in a bonus balance. That balance can look like money in the account without being treated as withdrawable funds. A specialist review identifies wagering requirements as a condition that may apply to free-spin winnings before a withdrawal is permitted. The result is a two-stage offer: the spins are granted first, then the resulting balance must satisfy the relevant bonus terms.

This matters when comparing a no-deposit casino bonus with a genuinely wager-free reward. “No deposit” describes how the spins are obtained. It says nothing, by itself, about whether the winnings are paid as cash. A wager-free offer is different because its winnings are treated as cash without playthrough. The label attached to the initial reward therefore cannot settle the value of the promotion.

The account balance should be read according to its category, not just its displayed amount. A bonus balance may be usable for further play but unavailable for transfer to a bank account or other deposit method. Until the applicable wagering condition has been met, the amount is a promotional entitlement rather than realised funds. A winning spin does not change that classification automatically.

The same issue applies where an offer is described as free slots with bonus spins or as a large free-spin package. More spins can create more opportunities to produce winnings, but they do not turn those winnings into cash merely by increasing the headline size of the offer. The relevant question is what happens to the resulting balance after the spins have been used.

No-deposit offers describe how spins are obtained, but they do not guarantee that winnings are immediately withdrawable as cash without wagering requirements.

Terms for no-deposit spins should therefore be separated into three points: whether the spins themselves require a deposit, whether winnings are held as bonus funds, and what must happen before those winnings can be withdrawn. Combining these points produces the familiar but inaccurate assumption that “free” means immediately cashable. In accounting terms, the spins are the benefit received; the balance created by them may still be conditional.

When Bonus Winnings Become Real Money

“Real money” is not a label for every amount shown in a casino balance. It describes funds that can be withdrawn under the offer’s stated conditions, rather than a temporary bonus balance that still has playthrough attached.

A wager-free offer has a clear accounting treatment: the winnings are paid as cash and do not require further playthrough. A specialist review describes this type of reward as immediately cash-based, although the operator’s own terms still determine any separate withdrawal conditions. The important distinction is that the promotional value does not remain locked behind a wagering calculation.

A deposit match works differently when its bonus funds carry a wagering requirement. The balance may appear in the account and may be available for placing bets, but that does not make it withdrawable cash. Any winnings generated while the bonus remains restricted can also remain subject to the same promotional conditions. The displayed balance therefore has two possible components: money that can be cashed out and money that exists only for bonus play.

UK Online Casino Reload Bonuses: How They Work

This matters particularly when an offer is presented as a large percentage match. A headline figure can describe the amount credited for promotional play without describing the amount available for withdrawal. Until the applicable conditions have been met, the bonus portion should be treated as conditional value, not as income or accessible funds.

The practical test is simple: the account terms should state whether the balance is cash or bonus money, whether playthrough applies, and when the restriction is removed. If the offer is genuinely wager-free, winnings are treated as cash without playthrough. If a wagering condition remains, the balance has not yet become real money in the cashout sense, regardless of how prominently it is displayed.

Deposit Matches: Calculate the Match, Not Just the Percentage

A deposit match is not a single figure until the qualifying deposit and the ceiling are known. A 100% match means the bonus mirrors the eligible deposit, but only up to the stated maximum. A £100 qualifying deposit under a 100% match would therefore produce a £100 bonus; a deposit above the ceiling would not create an unlimited reward.

Final Summary

• A deposit match is defined by the qualifying deposit and the maximum ceiling
• Multi-stage packages may have different match rates for subsequent deposits
• Always separate the headline percentage from the actual bonus amount produced

The structure becomes less straightforward when a welcome package is split across several deposits. A specialist review describes an arrangement in which the first deposit receives a 100% match capped at £500. Later deposits then carry different match rates, between 50% and 75%, with additional free-spin allocations. The headline percentage across the package can therefore look much larger than the reward attached to the first transaction.

That distinction matters for any offer presented as a 600% casino deposit match in the UK market. The percentage may refer to the combined package rather than one deposit. It may also depend on completing each stage in sequence. Treating the headline as an immediate cash addition produces the wrong calculation.

A clean comparison separates each stage:

• qualifying deposit;
• match rate;
• maximum bonus for that stage;
• whether another deposit is needed to unlock the next stage;
• any free spins attached to that deposit.

For instance, the first stage described above could add £500 only when the qualifying deposit reaches the level at which the cap is fully used. A later deposit would be assessed under its own 50–75% rate, not retroactively at 100%. The free spins are a separate part of the package rather than an increase to the deposit match.

The useful figure is consequently the bonus produced by the deposit actually being considered. A multi-stage total is a schedule of possible rewards, not money credited in one step.

“No Wagering” Spins: Check the Withdrawal Cap

A “no wagering” label describes the playthrough condition attached to the spin winnings. It does not, by itself, state how much of those winnings may be withdrawn. The two conditions are separate: one concerns whether further qualifying play is required, while the other concerns the maximum payout permitted by the offer.

A specialist review of free-spin promotions notes that some offers place a withdrawal cap on winnings from the spins. In practical terms, a winning balance can therefore exceed the amount that the promotion allows to leave the casino account. The displayed balance is not necessarily the transferable amount; the withdrawal condition decides that.

This distinction matters particularly when an offer is presented as wager-free. The label can make the reward appear simpler than it is, but the relevant terms may still restrict the cashout. A promotion can remove a playthrough requirement and retain a separate limit on winnings. Treating “no wagering” as “no conditions” is therefore an accounting error.

The terms for the spins should be checked for wording such as a maximum withdrawal, maximum winnings, or a cap applying specifically to free-spin returns. That clause needs to be read alongside the definition of the promotional balance, because the restriction may apply to winnings generated by the spins rather than to deposited funds.

Online casino with a 500% bonus: how it works

The result is a straightforward calculation: the amount credited after the spins is not enough to establish the amount available for withdrawal. The applicable cap must be identified first. If the offer does not make that condition clear, the headline description cannot establish the final cash value. A large spin allocation or a “600%” promotional label changes nothing about this point; the payout condition remains the controlling figure.

Terms That Change the Final Value

A headline reward has a value only while its conditions remain active. Expiry is therefore a financial term, not an administrative footnote. A specialist review reports that bonus funds and free spins may expire after a set period ranging from 7 to 30 days. The relevant period belongs to the individual promotion, so the welcome bonus terms and conditions take priority over any summary shown on a comparison page.

Expiry can apply to different parts of the package separately. The deposit match may have one deadline, while free spins or winnings generated from them may have another. A balance left unused when the applicable period ends can be removed, and unfinished qualifying play may no longer count towards a withdrawal. The offer’s stated deadline should therefore be checked before the deposit is made, not after the reward has been accepted.

UK Casino Cashback Bonuses: Compare the Terms

The account area is the practical control point. A specialist review reports that casinos provide an account section showing the bonus balance and progress towards the wagering requirement. That information allows the remaining promotional balance and outstanding qualifying play to be checked without treating the displayed amount as cash available for withdrawal.

The figures should be read together: remaining bonus funds, completed wagering progress, the applicable expiry date and any separate deadline for free-spin winnings. A large balance with little time left may have less usable value than a smaller balance with sufficient time to complete the conditions. If the account display does not make those items clear, the written terms remain the controlling record.

For a 600% casino bonus, the useful calculation is consequently not the percentage alone. It is the amount still active, the progress already recorded and the time remaining before the offer or its winnings disappear.
