How Online Casino Bonuses Work: Wagering Requirements Explained
An online casino bonus is extra money or free spins that a casino gives you for signing up or depositing, with conditions attached. The main condition is the wagering requirement, which is the amount you must bet before you can withdraw the bonus or any winnings it produced. A 100 bonus with a 30x requirement means you must place 3,000 in total bets first.
This guide explains how wagering requirements are calculated, which terms change a bonus’s real value, how to work out whether an offer is worth taking, and what changed for UK players in 2026.
Short Answer: Wagering requirement = bonus amount (or bonus plus deposit) multiplied by the stated number. Bets on different games count at different rates, bonuses have time limits and maximum bet rules, and many cap how much you can cash out. Read those four things before you accept any offer.

What a casino bonus actually is
A bonus is a marketing tool. The casino gives you extra playing credit because it expects you to keep playing, and the conditions exist so that it does not lose money on people who take the credit and leave. That is not a scandal. It is simply how the offer is built, and it means you should read a bonus as a contract, not a gift.
Most problems come from one gap. Players see the headline, such as “200% up to 500”, and assume that is money they can keep. In reality, it is money you can play with, and you can only withdraw what is left after meeting the terms.
Common types of casino bonuses
Offers differ in name and design, but most fall into a handful of types.
| Bonus type | How it works | What to watch |
|---|---|---|
| Welcome or deposit match | The casino adds a percentage of your deposit, for example 100% of 100. | Wagering multiplier, whether it applies to the deposit too, expiry. |
| Free spins | A set number of spins on a chosen slot at a fixed value per spin. | Wagering usually applies to the winnings, plus a cap on what you can withdraw. |
| No-deposit bonus | A small amount or spins given without you paying anything. | Often high wagering and a low maximum cashout. |
| Cashback | A percentage of net losses returned over a period. | Some cashback is cash, some carries wagering. Check which. |
| Reload bonus | A deposit match for existing players, often weekly. | Same terms as welcome bonuses, sometimes tighter. |
| No-wagering bonus | Winnings are yours with no playthrough, or a very low one. | Usually smaller in value and may have a withdrawal cap. |
How wagering requirements work
A wagering requirement is a multiplier. The casino multiplies it by a base amount and the result is the total you must bet before withdrawing.
Here is a plain example.
- You deposit 100 and receive a 100 bonus.
- The terms say 30x on the bonus amount.
- 100 x 30 = 3,000 in total bets.
You do not need to have 3,000 in your account. Every bet counts toward the total, including bets you place with money you already won. If you bet 1 per spin, that is 3,000 spins. If you bet 5 per spin, it is 600 spins. The requirement measures how much you bet in total, not how much you lose.
Your balance goes up and down while you clear it. If you run out of money before reaching the total, the bonus and any remaining balance are gone. So the multiplier tells you how long you must keep playing, and the longer you play, the more likely the house edge takes your balance.
Bonus only or deposit plus bonus
This detail changes the math a lot, and it hides in the terms.
Take a 100 deposit and a 100 bonus, with a 30x requirement.
- Applied to the bonus only: 100 x 30 = 3,000 total bets.
- Applied to the deposit and the bonus: (100 + 100) x 30 = 6,000 total bets.
Same headline number, double the playthrough. Always look for the words “bonus only” or “deposit plus bonus” in the terms. If the casino does not say, ask support in writing and keep the answer.
Game contribution rates
Not every bet counts the same. Casinos assign a contribution percentage to each type of game.
| Game type | Typical contribution |
|---|---|
| Slots | 100% |
| Table games such as blackjack and roulette | Often 10% to 20%, sometimes 0% |
| Live dealer games | Often low, sometimes excluded |
| Video poker | Often low |
These figures vary by casino, so use them as examples, not rules. The effect is large. Suppose you must wager 1,750 and play blackjack at 10% contribution. A 100 blackjack bet adds only 10 toward the total. You would need to place 17,500 in blackjack bets to clear the same requirement. A “35x” bonus effectively becomes 350x for a table game player.
Some casinos also exclude certain slots entirely, usually those with a very high payout rate or features that let players reduce risk. The excluded list is in the terms, not on the promotion banner.
Other terms that change a bonus’s value
The wagering number is only one part. These terms often matter just as much.
Maximum bet while a bonus is active. Casinos limit how much you can bet per spin or hand while you have bonus funds. Going over the limit, even once and even by accident, can cancel your bonus and winnings. Check this limit before you raise your stake.
Time limit. Bonuses expire. Seven days is common, though some give 24 hours and others 30 days. A 3,000 requirement over seven days is a very different task than the same requirement over 30.
Maximum cashout. Some bonuses cap what you can withdraw from bonus winnings, no matter how much you win. This is especially common with no-deposit offers and free spins. A cap of 100 on a free spins offer means a 2,000 win turns into 100.
Minimum deposit. Offers have a minimum deposit to qualify. Make sure your deposit is above it, or you will get no bonus at all.
Payment method restrictions. Some e-wallets and prepaid methods do not qualify for bonuses. Read the list before you pick how to pay.
Country and game restrictions. Some offers are not available in every country, and some games do not count at all.
Bonus abuse clauses. Casinos can void winnings if they believe you broke the terms, for example by opening multiple accounts or placing risk-free bets. Keep to one account and follow the rules exactly.
Sticky and non-sticky bonuses
This difference decides how much control you have.
A sticky bonus cannot be withdrawn at all. Only the winnings made with it can be taken out, after you meet the requirement. The bonus itself is removed when you cash out.
A non-sticky (or “cashable”) bonus is played in a different order. The casino uses your real cash first. If you win and meet the conditions or cash out before the bonus is touched, you can leave with your own money and winnings, and the bonus is simply removed. If you lose your cash, the bonus funds activate.
Non-sticky bonuses give you more flexibility because you can walk away without being locked into the wagering. Sticky bonuses often look larger but restrict you more. The terms usually say which type applies, so look for those words.
How to tell if a bonus is worth taking
You can estimate a bonus’s value with a simple formula. It is not perfect, but it shows you whether the offer is attractive or a trap.
Expected cost = total wagering required x the casino’s edge on your game
The casino’s edge is 100% minus the game’s return to player (RTP). A slot with 96% RTP has a 4% edge. Over a very long run, you lose about 4 of every 100 you bet. This is an average, and your real session can swing far above or below it.
Run it on two offers, both giving a 100 bonus on slots with 96% RTP.
| Offer | Total wagering | Expected cost at 4% edge | Compared with 100 bonus |
|---|---|---|---|
| 30x on bonus | 3,000 | 120 | Costs more than the bonus is worth |
| 10x on bonus | 1,000 | 40 | Leaves roughly 60 of expected value |
On the first offer, you are expected to lose more than the bonus gives you. On the second, the offer leaves you ahead on average. Variance means you can still win or lose either way, but the math tells you which offer is built for your benefit.
This is only an estimate. It ignores expiry, max cashout and max bet rules, which can lower the real value further. Use it to compare offers, not to predict your result.
The UK 10x wagering cap
If you play at UK-licensed casinos, the rules changed in 2026. From 19 January 2026, the UK Gambling Commission limited wagering requirements on bonuses to a maximum of 10 times the bonus amount. The same set of reforms banned “mixed-product” bonuses, where a casino bonus depends on playing more than one product type, such as casino and sportsbook together. You can read the regulator’s current position on the UK Gambling Commission website.
In practice, this means a UK-licensed casino can no longer offer a 35x or 40x requirement. A 100 bonus now carries at most 1,000 in wagering. Online slot stake limits also apply in Great Britain, at 5 per spin for players aged 25 and over and 2 per spin for ages 18 to 24.
Two things to keep in mind. First, 10x is a ceiling, not a promise. A casino can set a lower requirement or none at all. Second, the cap applies to casinos licensed by the UK regulator. Casinos licensed elsewhere that accept players from other countries follow their own regulator’s rules, and many still use multipliers of 30x to 50x or higher. If you play outside the UK, expect those higher numbers and run the math before accepting.
No-wagering bonuses
Some casinos now offer bonuses with no wagering requirement at all. Anything you win from the bonus is yours to withdraw straight away. After the UK cap, more operators have leaned on this type of offer to stand out.
They are simple, but they are not free money. They are usually smaller, such as free spins with a modest value. They may also come with a cap on winnings or a short expiry. If you want the least complicated route, a no-wagering offer with clear terms is often easier to understand than a large bonus with a long playthrough.
Common mistakes that cost players their winnings
- Accepting a bonus automatically. Many casinos add the bonus when you deposit. If you do not want the conditions, you often have to opt out before depositing, or decline it in your account.
- Betting above the maximum. One oversized spin can void everything.
- Playing excluded games. If a slot does not count or is banned during a bonus, your wagering will not move, or your winnings can be removed.
- Withdrawing too early. Asking for a withdrawal before finishing the wagering often cancels the bonus and its winnings. Check what the casino does first.
- Missing the expiry. Wagering that is not finished by the deadline is lost.
- Not completing identity checks early. Casinos verify your identity before paying out. Upload documents as soon as you register so your payout is not delayed.
- Chasing losses to meet the requirement. If you find yourself depositing more just to unlock the bonus, stop. A bonus should never push you to spend money you had not planned to.
A quick checklist before you accept a bonus
- What is the wagering multiplier, and does it apply to the bonus only or to the deposit plus bonus?
- What is the total amount in bets, in real money?
- Which games count, and at what percentage?
- What is the maximum bet allowed while the bonus is active?
- How long do you have to finish?
- Is there a maximum cashout from bonus winnings?
- Is the bonus sticky or non-sticky?
- Which payment methods qualify?
- Are the terms written clearly, and can you save a copy?
If you cannot answer most of these from the terms, do not take the bonus. You can always play with your own money, which keeps withdrawals simple.
Responsible gambling and bonuses
Bonuses are designed to keep you playing. Treat them with the same caution you would any marketing offer. Set a budget before you start, use deposit limits and session reminders, and never gamble with money you need for bills, rent or food.
If gambling is causing you stress or money problems, talk to someone early. In Great Britain, GamStop lets you exclude yourself from all UK-licensed sites at once. You can also contact BeGambleAware or GamCare for free, confidential support.
FAQ
What does a 30x wagering requirement mean?
It means you must bet the bonus amount 30 times before you can withdraw. On a 100 bonus, that is 3,000 in total bets. Check whether the multiplier applies only to the bonus or to the deposit and bonus together, because the second version doubles the total.
Is a lower wagering requirement always better?
Not always. A low multiplier is a good sign, but you also need to check the game contribution, maximum bet, time limit and maximum cashout. A 10x bonus that expires in 24 hours or caps winnings at 50 may be worth less than a 20x offer with generous terms.
Can I withdraw my deposit while I have a bonus active?
Often not without losing the bonus. Many casinos cancel the bonus and any bonus winnings if you withdraw before finishing the wagering. Some separate your cash from the bonus balance, which is the non-sticky model. Read the terms to see which applies.
Do wagering requirements apply to free spins winnings?
Usually yes. Casinos typically apply the multiplier to winnings from free spins, not to the spins themselves. For example, if 20 spins win you 8 and the requirement is 40x, you must wager 320 before withdrawing that 8. Some offers have no wagering on spin winnings, and those state it clearly.
What is the UK wagering cap?
Since 19 January 2026, UK Gambling Commission rules limit wagering requirements on bonuses to 10 times the bonus amount. The cap applies to operators licensed in Great Britain. Casinos licensed in other jurisdictions follow their own regulators and may still use much higher multipliers.
Are no-deposit bonuses really free?
You do not pay to receive them, but they carry conditions. Most have wagering requirements, short expiry dates and a low cap on how much you can withdraw. They are useful for trying a casino with little risk, but they rarely lead to large payouts.
Why was my bonus winnings removed?
The most common reasons are betting above the maximum allowed stake, playing an excluded game, withdrawing before completing the wagering, missing the expiry date, or breaking another term such as using multiple accounts. Check the bonus terms and contact support in writing if you think a mistake was made.
