A casino bonus is a price with the price tag on the back. The front says 100% up to €200 and 30x wagering. The back says which of those two amounts the 30x multiplies, how much of each bet counts toward it, the largest stake allowed while clearing it, and the most you are permitted to withdraw once you have. Change any one of those and the same headline becomes a completely different offer.
Our guides cover the back of the tag. They are grouped into the four sections below: the bonus terms themselves, the withdrawal problems those terms cause, how slots behave while you clear a requirement, and how to judge whether the casino holding your money can be trusted with it.
Nothing here is a system for beating a casino. No such thing exists, and any guide claiming otherwise is selling something. The aim is narrower and more useful: knowing what an offer costs before you claim it, rather than after.

How Do Casino Bonuses Work?
A casino bonus is extra funds or free spins credited to your account in exchange for meeting playing conditions before the money can be withdrawn. The main condition is a wagering requirement: a total amount you must bet before bonus winnings convert to cash.
A bonus is not a gift. It is a marketing cost the casino expects to recover through the play required to release it, and every condition attached exists to make that maths work. That is not a reason to avoid bonuses, it is a reason to read them, because the gap between a well-priced offer and a badly priced one is large and almost never visible on the banner.
The useful part is that the same handful of terms decide the value of every bonus, whatever it is called. Learn those once and you can price any offer you are shown.
The Four Terms That Decide What a Bonus Is Worth
| Term | What to look for | Why it decides the value |
|---|---|---|
| What the wagering multiplies | “30x bonus” or “30x deposit + bonus” | On a 100% match, the second version is exactly twice as expensive for the same advertised number |
| Game weighting | The game contribution table in the terms | At 10% weighting a €3,000 target needs €30,000 in real bets, without changing any advertised number |
| Maximum bet while wagering | A fixed cap, or a percentage of the bonus | Exceeding it once can void the bonus and the winnings. The most common reason a genuine win is refused |
| Maximum cashout | A cap on withdrawable bonus winnings | Where one exists it is the real ceiling on the offer, whatever the headline amount says |
A fifth term decides whether clearing the requirement pays you anything at all: whether the bonus is sticky, meaning it is deducted from your balance at withdrawal, or non-sticky, meaning it converts along with the winnings.
The first term catches people out most. A wagering requirement is a turnover target, and the multiplier is only half the instruction. Bonus only vs deposit + bonus works through the maths and gives a one line formula for converting any offer into a single comparable figure. Weighting is covered in do slots count toward wagering requirements.
What Is a Good Wagering Requirement?
Below 25x the bonus is competitive, 30x to 35x is average, and above 40x is expensive. Those figures assume the multiplier applies to the bonus alone and that the games you play count 100%. If either is untrue, convert the offer first.
The 25x line is not arbitrary. Every bet is exposed to the house edge, so the expected cost of clearing a requirement is the turnover multiplied by 100% minus the game’s RTP. On a 96% RTP slot the house expects to keep 4% of everything you bet, which puts break-even at 25 times the bonus.
| Wagering (bonus only) | Verdict | Turnover on a €100 bonus |
|---|---|---|
| 0x | Wager free, winnings are cash | €0 |
| 10x to 20x | Excellent, and 10x is the UK legal maximum | €1,000 to €2,000 |
| 25x | Break-even on a 96% RTP slot | €2,500 |
| 30x to 35x | Average, and past break-even | €3,000 to €3,500 |
| 40x and above | Expensive, check the cashout cap too | €4,000 and up |
This is an average across many bets, not a prediction of one session. Results scatter widely around it, and high volatility games scatter most, which is why some players clear a 40x requirement and most do not.
How to Check a Bonus in Under a Minute
Open the full terms rather than the promotion page, then answer these in order.
- What does the wagering apply to? Search the terms for “deposit” near “wagering”. If both words appear in the requirement itself, the base is deposit plus bonus and the real cost is roughly double.
- What is the game weighting? Find the contribution table. If your games count less than 100%, divide 100 by that percentage and multiply the turnover target by the result.
- What is the maximum bet? Note it, and stay under it on every single bet until the requirement is fully cleared.
- Is there a maximum cashout? If so, that number is the ceiling on the whole offer.
- Is the bonus sticky? A non-sticky bonus converts with the winnings. A sticky one does not.
If the published terms cannot answer all five within a couple of minutes, that tells you something about the operator as well as the offer.
Casino Bonus Types, and Where to Compare Them
Bonus types are packaging. The terms above still decide the value inside each one. Here is what each is for, and where the current offers available in your country are listed.
- Welcome bonuses are the largest offers a casino makes and usually carry the heaviest conditions, because they are priced to be claimed once. See welcome bonuses and first deposit bonuses.
- Free spins are wagered on the winnings rather than on any deposit, making them a genuinely different calculation. How free spins work, and offers at free spin bonuses.
- No deposit bonuses cost nothing to claim, which is why they carry the tightest cashout caps of any type. Treat the cap as the real value. See no deposit bonuses.
- Reload bonuses are where a punishing structure hides most easily, because the headline percentage is small enough that few people check the base. What is a reload bonus, and reload bonuses.
- No wager bonuses remove the turnover target entirely and pay winnings as cash, normally in exchange for a smaller headline figure. Often the best genuine value available. What is a no wager bonus, and wager free bonuses.
- Cashback returns a share of losses rather than adding funds up front, so it is priced on the percentage and the period instead of a multiplier. See cashback bonuses.
- Crypto bonuses apply wagering to deposit plus bonus more often than most, and an offer held in a volatile currency can move in real terms while you are still clearing it. See crypto casino bonuses.
- High roller offers trade a larger amount for a larger absolute requirement, and are worth taking only at stakes you were going to play anyway. See high roller bonuses.
Rakeback sits outside this list. It is a returning-player mechanism rather than a bonus, usually carries no wagering at all, and is often better value than the offers advertised hardest.
Do Casino Bonus Rules Change by Country?
Considerably, and not only for legal reasons. The same brand can run a 10x bonus-only offer under one licence and a 40x deposit-plus-bonus offer under another, with genuinely different terms on each.
In Great Britain, changes to the Gambling Commission’s Licence Conditions and Codes of Practice took effect on 19 January 2026. Social Responsibility Code 5.1.1 prevents licensees requiring customers to play through bonus funds more than 10 times, and bans bundling casino and sports offers into a single incentive. In Sweden, Chapter 14 Section 9 of the Gambling Act permits a licence holder to offer a bonus only on a player’s first occasion of play, so Swedish licensed casinos run one welcome offer and no reloads at all. Most other markets, including the offshore licences many international casinos hold, cap neither the multiplier nor the base.
Offers listed across this site show what is available to players from your country, so what you see already reflects your market rather than a generic global list. Which licence an operator holds is the strongest single predictor of how its terms are written, covered in which casino licence is best.
Where to Start
Bonus Basics if you are working out whether a specific offer is worth claiming. It covers the terms, the types and the vocabulary everything else assumes.
Withdrawal & Money if money is already stuck. Almost every blocked withdrawal traces back to a bonus term rather than a payment problem, and identifying which term applies decides what can be done.
Slots & Games for the maths of the games you clear a requirement on. RTP and volatility decide what a given turnover target really costs, which is why identical bonuses played on different slots end very differently.
Safety & Trust before depositing somewhere unfamiliar. A casino’s licence decides what happens on the day a withdrawal is refused, and licences are not equivalent.
Independent, Clear and Player-Focused
These guides are written to be checked rather than believed. Where a figure comes from a regulator or a game studio, the guide names the rule or the source. Where sources disagree, it says so instead of quietly picking the convenient one.
We earn commission when a player signs up through this site, which is how it is funded. That is worth knowing when reading anything here, and it is why the guides keep the parts that do not help conversion: that most wagering requirements have negative expected value past a certain multiplier, that no deposit bonuses are usually capped low enough to be close to worthless, and that some offers are simply not worth claiming. A guide that never says no is an advert.
Sometimes, and it depends on numbers you can check before claiming. A bonus is worth taking when the bonus amount is larger than the expected cost of the turnover attached to it. On a 96% RTP slot the house expects to keep 4% of everything you bet, putting break-even at roughly 25 times the bonus. Common 35x and 40x offers already sit past that point.
What the wagering multiplier applies to. Everything else is secondary, because that one clause can double the cost of an offer without changing the advertised multiplier. Check whether the requirement names the bonus alone or the deposit and bonus together before comparing it with anything.
Below 25x the bonus is competitive, 30x to 35x is average and above 40x is expensive, assuming the multiplier applies to the bonus alone and your games count 100%. Anything at 10x or under is excellent, and 10x is the legal maximum for casinos licensed in Great Britain.
Convert both to the same unit. Express each as a multiple of the bonus alone, then apply the game weighting for the games you actually play, then compare. Comparing advertised multipliers directly is the most common mistake, because two offers both labelled 30x can differ in real cost by a factor of two or more.
A no wager bonus, where one is available. There is nothing to convert, no turnover target, and winnings are cash. The headline amount is smaller than a match offer but the value is real rather than conditional. Failing that, a low bonus-only multiplier with full slot weighting and no maximum cashout.
No. Most casinos let you decline at the cashier or in account settings. Depositing without a bonus means your money is not locked behind a wagering requirement and can be withdrawn whenever you like. If you are depositing to play rather than to clear an offer, declining is often the better choice.
It can void a bonus and any winnings from it if you breach the terms, most commonly by exceeding the maximum bet while wagering or by playing an excluded game. It cannot reasonably void anything after the requirement has been fully met and the funds have converted to cash. If that happens, the question stops being about the bonus and becomes about the operator’s licence.
Because the play required to release a bonus generates more expected revenue than the bonus costs. Every attached condition exists to make that calculation work. It is the business model rather than a scandal, and understanding it is what lets you spot the offers where the maths happens to fall your way.
Considerably, because regulators set different rules. Great Britain caps wagering at 10 times bonus funds as of 19 January 2026. Sweden permits a bonus only on a player’s first occasion of play. Most offshore licensed markets set no cap at all, so the same brand can offer very different terms depending on which licence covers your registration.
Yes, and people do. What varies is how likely it is and how much you can keep, set by the wagering requirement, the game weighting and any maximum cashout. A bonus with a 5x cap can never pay more than five times the bonus whatever you win, so read that cap before treating a large headline figure as a large opportunity.
At most casinos you forfeit the bonus and everything won with it, keeping only your remaining real-money balance. Some block the withdrawal entirely until the requirement is met. Taking the forfeit is sometimes still right, particularly when the remaining turnover is large and the balance is mostly your own money.
Not on its own, and under a deposit-plus-bonus requirement the relationship runs backwards. Because your deposit stays in the calculation however small the bonus is, a 25% match with 30x deposit-plus-bonus wagering works out at 150 times the bonus, while a 300% match on identical terms works out at 40 times. Small percentages with that structure are the worst offers commonly advertised.
