Most players look at a bonus amount and get excited without reading the small print. The casino playthrough requirement is the number that tells you how much you actually have to bet before you can take any winnings out. Getting this wrong can cost you a lot of money, so it is worth spending two minutes understanding how it works before you accept any offer.

A 200 pound welcome bonus with a 40x playthrough means you must place 8,000 pounds worth of bets before you can withdraw. That is the kind of detail this guide covers in plain language, from the basic formula to what the rules look like for players in the UK and Norway.

What Is a Casino Playthrough Requirement?

When a casino gives you a bonus, they want to make sure you actually play with it rather than just withdrawing it straight away. To do this, they add a playthrough condition. This is a multiplier that tells you how many times you need to wager your bonus before the money becomes real cash you can withdraw.

You will see this condition written in different ways depending on which site you use. They all mean the same thing:

The UK Gambling Commission tells casinos they must show wagering requirements clearly and in plain language. Even so, some casinos still hide the important details in long terms pages. Always find the wagering requirement number before you accept a bonus

Bonus Only vs. Bonus And Deposit Casino Playthrough Requirements

This is one of the most important things to check. Some casinos apply the playthrough multiplier to your bonus amount only. Others apply it to the combined total of your deposit and your bonus. That one difference can double the amount you need to bet.

CHECK THIS FIRST

Always find out whether the playthrough applies to the bonus only or to your deposit and bonus combined. A 20x requirement on a 100 pound bonus only means you need to bet 2,000 pounds total. The same 20x requirement on your 100 pound deposit plus 100 pound bonus means you need to bet 4,000 pounds. Same offer, but twice the work.

How to Calculate a Playthrough Requirement

The calculation is simple once you know which type of bonus you have. There are two versions

FORMULA A: BONUS AMOUNT ONLY

Total to Bet = Bonus Amount x Playthrough Number

Example: You get a 100 pound bonus with a 30x playthrough. 100 x 30 = 3,000 pounds total betting required. You must place 3,000 pounds worth of bets before you can withdraw.

FORMULA B: DEPOSIT AND BONUS COMBINED

Total to Bet = (Deposit + Bonus) x Playthrough Number

Example: You deposit 100 pounds and get a 100 pound bonus with a 30x playthrough. (100 + 100) x 30 = 6,000 pounds total betting required. That is double the amount compared to Formula A

Is the Bonus Actually Worth Claiming?

Knowing how much you need to bet is useful, but the more important question is whether the bonus will leave you better or worse off after you finish the playthrough. This is called the expected value of the bonus.

Expected value tells you roughly how much money you can expect to gain or lose by the time you clear the wagering requirement. The house always has an edge, which means the longer you play, the more you are likely to lose. The question is whether the bonus covers those expected losses.

EXPECTED VALUE FORMULA

Expected Value = Bonus Amount – (Total Betting Required x House Edge %)

Good outcome example: 100 pound bonus, 35x playthrough, playing a slot with 98% return rate (2% house edge). Expected Value = 100 – (3,500 x 0.02) = 100 – 70 = +30 pounds. This bonus is statistically worth claiming.  Bad outcome example: 100 pound bonus, 35x playthrough, playing a slot with 96% return rate (4% house edge). Expected Value = 100 – (3,500 x 0.04) = 100 – 140 = -40 pounds. This bonus will cost you money on average. Skip it.

SIMPLE TIP

Every slot game has a return rate (called RTP) that tells you what percentage of bets it pays back on average. You can find this in the game info or paytable. A slot with a 98% return rate loses you less money per bet than one with a 94% return rate. Choosing the right game can turn a losing bonus into a winning one.

Steps to Work Out Your Wagering Obligation

Follow these steps any time you want to check whether a bonus is worth your time:

• Find the bonus amount from the offer page
• Find the playthrough multiplier in the bonus terms
• Check whether it applies to bonus only or deposit plus bonus
• Multiply accordingly to get your total betting requirement
• Find the return rate of the game you plan to play
• Use the expected value formula to see if the bonus is profitable

Once you have the expected value number, the decision is straightforward. A positive number means the bonus is worth claiming. A negative number means the casino will take back more than they gave you once the playthrough is complete.

4. How Different Games Affect Your Playthrough

Not every game counts the same toward your playthrough. Casinos assign a contribution percentage to each type of game. Slots usually count 100 percent, meaning every pound you bet clears a pound of your requirement. Table games like blackjack count much less, sometimes only 5 or 10 percent, which means you need to bet much more to clear the same amount.

Calculating Your Real Betting Requirement for Table Games

If you want to use a game that does not count 100 percent, you need to adjust your calculation. Divide your required playthrough amount by the contribution percentage to find out the real amount you need to bet.

ADJUSTED FORMULA FOR GAMES BELOW 100% CONTRIBUTION

Real Bets Needed = Playthrough Amount / Contribution Rate

Example: You have a 3,000 pound playthrough requirement and want to play roulette at 20% contribution. 3,000 / 0.20 = 15,000 pounds of actual betting required.  The same bonus that takes 3,000 pounds of slot bets to clear would take 15,000 pounds of roulette bets. Always check the contribution rates before you pick a game.

What Counts as a Fair Playthrough Requirement?

Not all bonus offers are equal. The higher the playthrough number, the harder it is to profit from the bonus. Here is a rough guide to how different ranges compare in 2026, particularly for UK players.

The UK Gambling Commission updated its rules in 2025 to crack down on bonus terms that are unfair or hard to understand. Most UK licensed casinos now offer playthrough requirements in the 20x to 40x range. More are now offering free spins with no wagering at all or low multiplier welcome bonuses as a result of this pressure.

UK RULE TO KNOW

UK Gambling Commission rules say casinos must display wagering requirements clearly and in simple language. If a casino makes the playthrough figure hard to find, or uses confusing wording, that is a warning sign worth taking seriously regardless of how good the bonus looks

Five Practical Tips for Clearing a Playthrough Requirement

Once you decide to claim a bonus, these five steps will help you clear the playthrough requirement in the most efficient way possible.

Pick Slots with a High Return Rate

Look for slots that pay back 96 percent or more. The higher the return rate, the less you lose per bet on average while working through your requirement. Check the game details page before you start. Even a small difference in return rate adds up over thousands of pounds of betting.

Check the Game Contribution List Before You Start

Open the bonus terms and find the list that shows what percentage each game type contributes. If your preferred games only count at 10 percent, your actual betting requirement is ten times higher than the headline number. This is worth checking before you even accept the offer.

Stay Within the Maximum Bet Limit

Most UK casino bonuses cap your bet size at around 5 pounds per spin while you are using bonus funds. Betting more than this limit will usually cancel your bonus completely, even if you are close to clearing the requirement. Set your bet size before each session and keep it within the allowed amount.

Keep an Eye on the Expiry Date

Most bonuses expire between 7 and 30 days after you claim them. If you cannot realistically place the full amount of required bets within that time, it is better not to claim the bonus at all. Once the deadline passes, the bonus and any winnings from it are removed automatically.

Always Calculate Expected Value Before Accepting

Before you accept any bonus, run the expected value calculation. If the result is negative, the house edge on your chosen game will eat through the bonus before you finish wagering. Only accept bonuses where the expected value is positive or very close to zero, unless you are playing purely for fun rather than profit.

UK and Norway: Key Playthrough Requirement Differences

Players in the UK and Norway operate under different rules. Knowing how these differences affect playthrough requirements will help you make smarter decisions.

Casino Playthrough Requirements Under UKGC Rules

The UK Gambling Commission oversees all licensed casino operators in the UK. Casinos must show playthrough requirements clearly, use honest advertising, and apply fair bonus conditions. In 2025, new stake limits came into force capping individual bets at 2 pounds for many players. This has made high-multiplier playthrough requirements take much longer to clear and cost more in the process. The most competitive UK casinos have responded by lowering their multipliers or switching to no-wagering bonus formats entirely.

What Casino Playthrough Requirements Apply to Norwegian Players

Norway runs a state gambling system through Norsk Tipping and Norsk Rikstoto. International online casinos are not officially licensed to serve Norwegian players, but many do. If you are in Norway and using one of these offshore casinos, the playthrough requirements on those sites are not covered by UK consumer protection rules. That said, many sites that accept Norwegian players hold licences from the Malta Gaming Authority or Gibraltar, both of which have similar standards to the UK in practice.

Common Questions About Playthrough Requirements

How do I work out my playthrough requirement?

Multiply the bonus amount by the playthrough number. A 100 pound bonus with a 30x requirement means you need to place 3,000 pounds in bets before you can withdraw. If the requirement covers your deposit as well, add your deposit to the bonus first and then multiply.

Is there a difference between a wagering requirement and a playthrough requirement?

No, they are the same thing with different names. Wagering requirement is the term used by the UK Gambling Commission and most European sites. Playthrough requirement and rollover requirement are the same condition, used mainly on global and US-facing sites. All three mean you must bet a set amount before you can withdraw.

What is a reasonable playthrough requirement in 2026?

Anything below 20x is a good deal and worth claiming in most cases. Between 20x and 35x is the standard range and can be cleared without too much difficulty if you choose the right games. Above 50x becomes hard to clear at a profit, and anything above 70x is generally not worth your time.

Do all games count equally toward the playthrough?

No. Slots usually count 100 percent, so every pound you bet clears one pound of your requirement. Table games like blackjack and baccarat often count only 5 to 10 percent, meaning you need to bet 10 to 20 times more to clear the same amount. Live casino games often count 0 to 5 percent. Always check the contribution table in the bonus terms before picking a game.

What happens if I do not finish the playthrough in time?

The bonus is cancelled and any winnings made with that bonus are removed. Most bonuses have a deadline of 7 to 30 days. Some casinos let you cancel a bonus yourself through your account settings if you decide you cannot meet the requirement. Doing this means your real money balance is not affected by the wagering terms.

Are playthrough requirements allowed in the UK?

Yes, they are legal. The UK Gambling Commission requires casinos to present them clearly and honestly. A casino that hides the playthrough figure or uses confusing language to mislead players can face action from the regulator. If you think a casino has treated you unfairly over bonus terms, you can report it to the UKGC or use an approved dispute resolution service.
