Casino Bonus Terms to Avoid: Wagering, Caps and Max Bets

The casino bonus terms to avoid are the ones that decide whether you can ever withdraw: high wagering on deposit plus bonus, a cap on what you can cash out, a maximum bet that voids winnings, game weighting that makes table games almost worthless, short expiry dates and vague “bonus abuse” clauses. In Great Britain, wagering on bonuses has been capped at 10 times since 19 January 2026; offshore casinos often set 35x to 50x.

None of these terms is hidden in the legal sense. They sit in the bonus rules, usually one or two clicks from the offer. The problem is that a headline such as “up to 5 BTC” tells you nothing about them. This page explains each clause, shows it in real published terms, and works through the maths so you can judge an offer in a few minutes.

What is the most expensive bonus term?

Wagering is the most expensive term because it decides how much you must bet before bonus money becomes cash, and every bet carries the house edge. A 40x requirement on a €100 bonus means €4,000 of bets. At a slot paying back 96% on average, that turnover costs about €160 in expected losses, more than the bonus itself.

Expected cost is turnover multiplied by the house edge (4% at 96% RTP); real results swing widely around it. The basis matters as much as the multiple: “35x deposit plus bonus” doubles the turnover of “35x bonus”. Published examples in October 2026 include 40x bonus wagering at BitStarz and mBit, 35x at 7Bit, and 50x at Koru Casino, each stated in its own bonus terms.

How do maximum cashout caps work?

A maximum cashout cap limits what you can withdraw from bonus play, however much you win. If the cap is five times the bonus and you took a €100 bonus, anything above €500 is removed when you withdraw. Caps are common on no-deposit offers and free spins, and some casinos also apply them to deposit bonuses.

Koru Casino’s bonus terms, for example, set a maximum cashout of five times the bonus on its welcome offer. A cap is not unfair in itself, because it is published, but it changes what an offer is worth: a high-volatility slot can produce a large win that the cap then cuts. Check whether the cap applies to the bonus only or to the whole balance, and whether your deposit counts towards it.

Why can one large bet void your winnings?

Most bonus terms set a maximum stake per spin or hand while the bonus is active, often €5 or less. Break it once and the casino may cancel the bonus and every winning made with it. Some casinos set the limit in the bonus terms in your account currency, so check the exact figure before you change your stake.

Foxy Gold’s published terms, for instance, set a €5 maximum bet with bonus funds and a €2,000 maximum win from bonus funds. The rule exists to stop players from using bonus money for a few huge bets, but it catches ordinary players who forget it, especially on games where one button doubles the stake. Lower your stake before you accept a bonus, not after.

What is game weighting?

Game weighting decides how much of each bet counts towards wagering. Slots usually count 100%. Table games and live dealer games often count 10%, 5% or nothing. With a 10% weighting, a €4,000 requirement needs €40,000 of blackjack bets, so table players gain little from most casino bonuses.

Some terms go further and exclude specific slots, usually high-RTP or jackpot titles, from bonus play altogether. Playing an excluded game can be treated as a breach, so read the list. If a bonus forbids the games you actually play, decline it: you can keep your deposit as cash and withdraw it at any time.

How short can a bonus expiry be?

Expiry clauses give you a fixed time to accept, use and clear a bonus. Seven days is common for wagering, free spins can last one to three days, and some offers expire within 24 hours of the deposit. When time runs out, the casino removes the bonus and any winnings still tied to it, and sometimes forfeits the free spins outright.

BitStarz’s bonus terms, for instance, give seven days to complete wagering; free spins at Winz.io are valid for one day. Combine a short expiry with high wagering and the offer becomes a race: €4,000 of bets in seven days means about €570 a day. If that is more than you would normally play, the bonus is pushing you to gamble more, not rewarding you.

What are free spins really worth?

Free spins are worth the stake per spin multiplied by the number of spins, multiplied by the slot’s return, before any wagering on the winnings. One hundred spins at €0.10 on a 96% slot have an expected value of about €9.60. If the winnings then carry 40x wagering, most of that value disappears in the turnover.

The middle row shows why “free” spins with high wagering are often worth nothing on average: the expected cost of clearing them exceeds the expected winnings. Spins split across several days, such as 20 a day for eight days, also require you to log in daily, which is a design that keeps you playing. Look for the spin value, which many promotions do not state; if it is missing, ask support before you accept.

Are “no wagering” and cashback offers better?

Usually, because what you win is cash. A no-wagering offer pays winnings straight into your withdrawable balance, and cashback returns a share of losses, sometimes with light wagering. Both are simpler to value, but read the conditions: cashback may be paid as bonus money, may exclude some games, and may have a cap.

Winz.io, for instance, advertised a welcome wheel with no wagering on its prizes in October 2026, while FortuneJack’s welcome missions asked players to wager each deposit 10 times on eligible games. These are lighter than the 35x to 50x welcome packages common offshore, but they are still promotions designed to encourage play, and the house edge applies to every bet you make to unlock them.

Can a casino change bonus terms after you accept?

It should not change the terms of an offer you have already accepted to your disadvantage. In Great Britain, the CMA’s 2018 action made clear that significant terms must be shown up front and that players must be able to reach their own money. Offshore terms often reserve a right to amend “at any time”, which is why you should save a copy on the day you accept.

Take a screenshot or PDF of the promotion page and the bonus terms when you opt in. If the casino later applies a different wagering rate, cap or excluded-games list, that copy is your best evidence. Disputes that start this way often end at the payment stage, so the steps in our chargebacks and crypto guide and the closure risks on our closed casinos page are worth knowing before you deposit.

What are sticky and non-sticky bonuses?

A sticky bonus cannot be withdrawn: it is removed from your balance when you cash out, even after wagering. A non-sticky bonus keeps your deposit separate and lets you play with real money first; the bonus only comes into play once your cash is gone. Non-sticky offers are usually better for players because you can stop and withdraw your own money at any point.

The British regulators targeted the locked-deposit problem directly. After a Competition and Markets Authority investigation with the Gambling Commission, Ladbrokes, William Hill and PT Entertainment committed in February 2018 to let players withdraw their own money without having to meet bonus wagering first. The Commission expected the whole sector to remove similar terms by 3 April 2018.

Why are “bonus abuse” clauses risky?

Bonus abuse clauses let a casino void a bonus and its winnings if it decides your play broke the spirit of the offer. Clear rules, such as one bonus per household, are fair. Vague ones, such as “irregular play” or “betting patterns we consider abusive”, give the casino a free hand at the moment you try to withdraw.

• Duplicate accounts: one account per person, household, IP address or payment method. Shared flats and families are often caught.
• Low-risk betting: covering both red and black, or most numbers on roulette, to clear wagering. Many terms ban it outright.
• Stake switching: small bets while wagering, then a large bet once the bonus clears, or the reverse.
• Game switching: moving to excluded or low-weighted games during wagering.
• “Any other pattern”: a catch-all clause that should make you cautious about the whole offer.

If a withdrawal is refused under one of these clauses, ask the casino in writing which clause, which bets and which dates. A specific answer is something an adjudicator can review; a refusal to give one is itself evidence. Our guide to complaining about a casino explains where to take it.

Do minimum withdrawal rules affect bonuses?

They can. A minimum withdrawal of €100, as published by several Softon brands in October 2026, means a balance of €80 left after wagering cannot be cashed out until you deposit or win more. Combined with a bonus, a high minimum keeps small winners playing. The CMA’s 2018 commitments with BGO specifically covered terms that stopped players withdrawing their full balance through minimum withdrawal limits, so British players should not meet this at licensed sites; offshore, check it before you opt in.

What changed in UK bonus rules in January 2026?

From 19 January 2026, Gambling Commission licensees may not set wagering requirements above 10 times the bonus, and may no longer offer promotions that require players to use more than one type of gambling product, such as betting on sport to unlock casino spins. Offshore casinos are not bound by these rules, which is one reason their offers look larger.

The Commission said the cap was meant to reduce harm and make offers easier to understand. A 10x cap on a €100 bonus means €1,000 of bets, about €40 of expected cost at 96% RTP, compared with €160 at 40x. When you compare a licensed offer with an offshore one, compare the expected cost, not the headline amount.

How do you check a bonus in five minutes?

Open the bonus terms, not the promotion page, and find six numbers: the wagering multiple, what it applies to, the maximum bet, the maximum cashout, the expiry and the weighting of the games you play. Then do one sum: bets required multiplied by the house edge. If that cost is close to or above the bonus, the bonus is worth little to you.

1. Wagering multiple and basis (bonus only, or deposit plus bonus).
2. Maximum bet while the bonus is active.
3. Maximum cashout from bonus winnings, if any.
4. Expiry for accepting, using and clearing the bonus.
5. Weighting and excluded games for what you actually play.
6. Whether you can decline the bonus and keep your deposit as cash.

Bonus terms also explain many disputes we see on our withdrawal delays page: a casino that pays deposits quickly can still hold winnings for weeks while it checks bonus play. If the terms are unclear or keep changing, that is a warning sign in its own right, listed in our rogue casino checklist.

Does declining the bonus protect you?

Usually, yes. Without a bonus there is no wagering, no maximum bet, no cashout cap and no abuse clause to argue about: your deposit and winnings are cash. Most casinos let you opt out at deposit or contact support to remove an unused bonus. Check that a bonus has not been added automatically, because some cashiers tick the box for you.

Declining does not change the house edge or make an unlicensed casino safe, so the other checks still apply. Look up the licence on the regulator’s register with our licence check guide, and keep balances small at any offshore site.
