Wagering requirements explained, with worked examples

Every casino bonus comes with a condition that decides whether it is worth anything at all: the wagering requirement. The headline percentage tells you how much bonus money you might receive. The wagering requirement tells you how much you have to stake before any of it, or anything you win with it, can be withdrawn.

This guide walks through the arithmetic with real numbers, so you can price an offer yourself rather than relying on the banner. The examples use pounds and round figures to keep the sums readable.

What a wagering requirement actually is

A wagering requirement (also called a playthrough or rollover requirement) is a multiple. If a bonus has a 10x requirement on £50 of bonus funds, you need to place £500 in total bets before the bonus converts into withdrawable cash. It is not £500 you have to lose; it is £500 of turnover. A £1 spin that wins £2 still counts as £1 of turnover.

The multiple is only half the story. Three other details change the amount you need to stake far more than most people expect:

• What the multiple applies to: the bonus alone, or the deposit plus the bonus.
• Game weighting: how much each game type contributes towards the target.
• Time limit: how many days you have before the bonus and its winnings expire.

Bonus-only versus deposit plus bonus

This is the clause that quietly doubles the work. Take a £50 deposit matched with a £50 bonus and a 35x requirement:

• On the bonus only: 35 x £50 = £1,750 of turnover.
• On deposit plus bonus: 35 x £100 = £3,500 of turnover.

Same advert, same percentage, twice the staking. When you read any set of bonus terms, find the sentence that says what the multiple is calculated on before you look at anything else.

The real cost: turnover times house edge

Here is the part most bonus pages skip. Every casino game has a built-in house edge, which is simply 100% minus the return to player (RTP). A slot with 96% RTP has a 4% edge. Over a large amount of play, your expected loss is roughly:

Expected loss = total turnover x house edge

That means you can estimate what clearing a bonus is likely to cost before you start. If the expected loss is smaller than the bonus, the offer has positive value on paper. If it is larger, you are, on average, paying for the privilege of playing with bonus money.

Worked examples

All rows assume a £50 bonus and slots at 96% RTP (4% house edge), with slots counting 100% towards wagering.

Two points stand out. First, the multiple matters more than the size of the bonus: a modest bonus at 10x can be worth more than a large one at 35x. Second, game RTP matters. The same 40x requirement costs half as much in expectation on a 98% game as on a 96% one, which is exactly why casinos often reduce or exclude the contribution of high-RTP games.

These are averages, not predictions. Short sessions swing wildly in both directions, and on high-volatility slots most attempts to clear a bonus end with the balance at zero before the target is reached, while a few end well above it. The expected loss tells you the price of the ticket, not the result of any single attempt.

Game weighting

Game weighting is a percentage that tells you how much of each stake counts towards wagering. A typical pattern looks like this:

• Slots: 100% (each £1 staked counts as £1)
• Table games such as roulette or blackjack: often 10% to 20%, sometimes 0%
• Live casino: frequently 0% or a low figure
• Specific named slots: sometimes excluded entirely

If blackjack contributes 10%, clearing £1,750 of wagering on blackjack would take £17,500 of actual bets. Playing an excluded game with bonus funds can also void the bonus outright, so the weighting table in the terms is worth reading line by line.

Maximum bet rules

Almost every bonus includes a maximum stake while bonus funds are active, commonly expressed as a fixed amount per spin or round. Exceeding it, even once, can give the casino grounds to cancel the bonus and any winnings made with it. This rule voids more bonuses than any other single clause, usually because a player raised their stake after a good run without rechecking the terms.

Expiry and the order money is used

Bonuses expire. A requirement that is easy over 30 days can be unrealistic over 7 if you play casually. Also check the order in which funds are used: many sites take stakes from your real-money balance first, others from the bonus balance first, and some lock your deposit until wagering is complete. That last arrangement matters because it decides whether you can walk away with your own money if you change your mind.

The UK picture: the 10x cap

For operators licensed by the Gambling Commission to serve customers in Great Britain, wagering requirements on bonuses have been capped at 10 times the bonus amount since 19 January 2026. The same package of changes also restricted promotions that mix different products, such as betting and casino, in a single offer. You can read the regulator's guidance on the Gambling Commission website.

The cap only applies to GB-licensed operators. Offers from casinos licensed elsewhere are not bound by it, which is one reason headline percentages in the international market can look so much larger. A bigger percentage paired with a much higher multiple can easily be worth less than a smaller, capped offer. Our page on judging whether a casino is right for you explains how to check which regulator a site answers to.

Applying this to the Trixino Casino offers

Trixino Casino advertises a welcome package of 777% up to €7,777, spread over the first deposits, and a weekly reload of 400% up to €3,500. Both figures describe a maximum, not what a typical player receives. The useful questions are the ones above, and the current answers are in the promotional terms on the casino site, which can change, so we do not quote fixed multipliers here.

1. Find the wagering multiple for each stage of the welcome package and whether it applies to bonus only or deposit plus bonus.
2. Check the game weighting table and any excluded titles.
3. Note the maximum bet while a bonus is active and the expiry period.
4. Run the turnover x house edge sum on the deposit you actually intend to make, not the maximum.

Our Trixino Casino bonus guide goes through the structure of the package in more detail. Regular players should also look at the VIP programme, because weekly offers with lower wagering can be worth more over time than a one-off headline package, for precisely the reasons shown in the table above.

When declining a bonus is the better choice

You can almost always deposit without taking a bonus. Doing so means your balance is yours to withdraw at any point, with no stake caps and no excluded games. If you mainly play live tables, prefer short sessions, or simply want flexibility, playing without a bonus is often the rational choice rather than the cautious one.

Bonuses should never be a reason to deposit more than you planned. Set your budget first, then decide whether an offer fits it. If gambling is starting to feel like something you need to win back, our responsible gambling page lists free, confidential UK support.
