Free Spins Wagering Requirements: the Terms Sit on the Winnings, Not on the Spins
The spins are free and that part is true. What is not free is what happens to whatever they win, and almost every argument about a free spins offer turns out to be an argument about one line in the terms: whether the winnings arrive as cash or as bonus funds. Everything else on this page follows from that line, including the British cap on how much play-through can be demanded, which is written about bonus funds and therefore only reaches an offer that creates some.
What the rule caps, in its own words
The Gambling Commission sets a ceiling on play-through in the social responsibility code provision on rewards and bonuses. The operative sentence is short enough to quote whole, and worth quoting because the second-hand versions of it drop the words that matter. Licensees must not “apply wagering requirements, which requires a customer to play through bonus funds, over a maximum of 10 times”.
Read the subject of that sentence rather than the number in it. The cap governs the play-through applied to bonus funds. It does not say that free spins must exist, that their winnings must be credited in any particular way, or that a cash credit is owed to anyone. It says that where funds are credited as a bonus, the multiple demanded of them stops at ten. An offer that credits winnings as cash is outside the sentence because it has created no bonus funds; an offer that credits them as bonus funds is inside it, and ten is the most it can ask.
Two neighbouring requirements in the same provision are worth carrying alongside it. Terms attached to an incentive have to be “clear, transparent, and fair and readily accessible” to the customer being offered it, which is the standard against which a set of free spins terms is measured rather than a matter of taste. And an incentive must not “include more than one type of gambling product (betting, casino, bingo, and lottery) within an incentive”, which is why a promotion cannot require a casino play-through to release something granted for betting. The full text of the cap is in our guide to the 10x wagering cap, and the general mechanics are in understanding wagering requirements.
The one line in the offer that sets the size of the obligation
Three crediting models cover almost every free spins offer on the British market. They look similar in the advertising and behave nothing alike once the spins have finished.
| Model | How the winnings are credited | Play-through that follows | What it means in practice |
|---|---|---|---|
| Winnings credited as cash | Whatever the spins win lands in the withdrawable balance straight away. | None on the winnings. There is nothing to play through, because nothing was credited as a bonus. | The cleanest version of the offer, and the rarest. The whole value of the spins is the value of the winnings. |
| Winnings credited as bonus funds | The amount won is added to a bonus balance that is separate from the cash balance. | A multiple of the credited amount must be staked before the balance can be withdrawn. | The usual version. The offer is not the spins, it is the spins plus an obligation that starts the moment they finish. |
| Bonus funds with a withdrawal cap | As above, with a stated maximum that can ever be withdrawn from the bonus, regardless of how much it wins. | The same multiple, applied to the same credited amount, with the outcome truncated at the cap. | The cap does its work only when the spins go well, which is exactly when the offer would otherwise be worth something. |
A second distinction sits underneath the first and is easy to miss. Where the winnings are credited as bonus funds, the multiple may be applied to the amount won or to a separate notional figure named in the offer. Ten spins that win four pounds create a four-pound obligation under the first arrangement. The arithmetic below uses the amount won, because that is the common case and the one a reader can check against their own balance.
The arithmetic, on ten pounds
Play-through has a price, and it can be calculated rather than felt. Staking a pound on a game that returns 96 per cent costs four pence in expectation. Turnover multiplies that cost: ten pounds of bonus funds at a 10x requirement is one hundred pounds of turnover, and one hundred pounds of turnover at a four per cent house edge has an expected cost of four pounds. The table works that through, holding the game at 96 per cent and the credited amount at ten pounds.
| Requirement | Turnover needed | Expected cost at 96% RTP | Expected value left |
|---|---|---|---|
| 1x | £10 | £0.40 | £9.60 |
| 3x | £30 | £1.20 | £8.80 |
| 5x | £50 | £2.00 | £8.00 |
| 8x | £80 | £3.20 | £6.80 |
| 10x | £100 | £4.00 | £6.00 |
| 25x | £250 | £10.00 | £0.00 |
The last row is the one that explains the cap. The multiple at which a bonus is worth nothing in expectation is one divided by the house edge: at four per cent that is 25x, at six per cent it is roughly 16.7x, and at three per cent it is over 33x. A legal ceiling of ten therefore sits below the break-even multiple at every return to player a British slot is likely to have. The cap does not make a bonus generous. It stops one being arithmetically empty, which is a smaller claim and a truer one.
Two honest caveats belong with those numbers. They are expectations over many repetitions and not a forecast of one evening: the distribution around them is wide, which is the whole appeal of a slot and also the reason the average is the only thing that can be stated in advance. And they ignore withdrawal caps, which are handled further down and can matter more than the multiple. To run the same calculation on a real offer, our wagering calculator takes the amount and the multiple, and the casino bonus EV calculator adds the return to player. The reasoning behind the break-even figure is set out in wagering multipliers explained.
Where the play-through is allowed to happen
A requirement expressed as a multiple is only half a requirement. The other half is the contribution table, which decides how much of each stake counts towards it. Slots commonly contribute in full, table games a fraction or nothing, and the games with the highest returns are usually the ones contributing least. That ordering is not an accident: contribution rates are set where the expected cost of the play-through would otherwise be lowest.
The effect is arithmetic rather than rhetorical. A fifty per cent contribution doubles the turnover required to discharge the same obligation, and doubling turnover doubles expected cost. A game listed as excluded contributes nothing while still taking the stake, which is the most expensive mistake available in this part of the process. Both are covered in game contribution rates and in excluded games compared with reduced contribution.
One further term belongs here because it carries the heaviest penalty for the smallest mistake. Many offers impose a maximum stake while a bonus balance is in play, often a few pounds, and breaching it can forfeit the balance outright rather than simply decline the bet. The rule and the way it is enforced are set out in the maximum bet rule during wagering.
Two clocks, and only one of them is advertised
Free spins carry an expiry date, and that date is usually the one in the advertising. A second and separate period governs the play-through on whatever the spins win, and it typically starts when the winnings are credited rather than when the offer was claimed. The two are rarely the same length, and the second is the one that forfeits a balance.
The practical consequence is that a set of spins played on the last permitted day can produce a bonus balance with a full wagering period still to run, while a set played immediately can leave the second clock expiring at an awkward moment. Neither arrangement is unusual or unfair; both are simply dates. What they do to a bonus balance when they pass is described in bonus expiry and forfeiture.
The ceiling above the ceiling
A maximum withdrawal cap states the most that can ever leave the account from a bonus, whatever it wins. Where one applies to free-spin winnings it changes the shape of the offer rather than its size: the play-through is unaffected, and so is the expected cost of completing it, but the upside is truncated at a fixed figure.
This is the term most likely to be discovered late, because it does nothing at all unless the spins go unusually well. A cap of fifty pounds is invisible on a four-pound win and decisive on a four-hundred pound one. How caps are drafted and where they bite is covered in maximum withdrawal caps on bonus winnings, and the comparison between a free bet and a deposit bonus, which divide the same problem differently, is in free bet against deposit bonus.
Reading a free spins offer in ninety seconds
Six questions, in this order, settle what an offer is worth. The first one answers most of it.
How are the winnings credited?
Cash or bonus funds. This single word decides whether anything else on this list matters.
What is the multiple, and of what?
A multiple of the winnings is a different obligation from a multiple of a notional bonus amount. Read which number it attaches to.
Which games count, and at what rate?
A fifty per cent contribution doubles the turnover needed. An excluded game contributes nothing at all while still taking the stake.
Is there a maximum stake while wagering?
Breaching it can forfeit the balance rather than simply reject the bet, and the limit is often a few pounds.
What are the two deadlines?
The date the spins expire, and the period allowed to finish the play-through afterwards. They are rarely the same length.
Is there a cap on what can be withdrawn?
A cap set below the plausible winnings turns a good outcome into a fixed one.
A step-by-step version of the clearing process itself, once an offer has been accepted, is in how to clear a casino bonus. Whether the multiple applies to the bonus alone or to deposit plus bonus is a separate question with a large effect, handled in deposit plus bonus against bonus only, and any unfamiliar term here is defined in the betting glossary.
What this page does not do
It names no operator and summarises no operator terms. Crediting models, contribution tables, stake limits and caps are contractual and they change without notice, so any figure taken from a page like this one and applied to a live offer would be a guess wearing a decimal point. The regulatory ceiling quoted above is a fact with a source; what any particular offer does underneath it is a fact about that offer, and the only reliable copy of it is on the site holding the balance. A broader look at how the surrounding terms fit together is in casino bonus wagering explained.
Frequently asked questions
Do free spins always come with wagering requirements?
Not always, and the difference is written into the offer rather than into any rule. Some offers credit what the spins win as cash, which can be withdrawn like any other balance. Others credit the winnings as bonus funds, and those funds carry a play-through obligation before they can be withdrawn. The spins themselves are free in both cases. The words to look for are cash, withdrawable or real money on one side, and bonus funds or bonus balance on the other.
What is the maximum wagering requirement allowed in Great Britain?
The social responsibility code provision on rewards and bonuses states that licensees must not apply wagering requirements, which requires a customer to play through bonus funds, over a maximum of 10 times. The cap is written about bonus funds, so it governs the play-through applied to funds credited as a bonus. Whether a particular offer credits free-spin winnings as bonus funds is a question about that offer terms, not about the cap.
How much is ten pounds of free-spin winnings worth at 10x?
In expectation, and before any withdrawal cap, about six pounds on a game returning 96 per cent. Ten pounds played through ten times is one hundred pounds of turnover, and the expected cost of one hundred pounds of turnover at a four per cent house edge is four pounds. On a game returning 94 per cent the same play-through costs six pounds and leaves four. The figure is an expectation across many repetitions rather than a forecast of one session.
Why does the game the wagering is cleared on matter so much?
Because the expected cost of the play-through is the turnover multiplied by the house edge of whatever is being played, so a lower return to player makes the same requirement more expensive. Contribution rates work in the same direction: if a game contributes fifty per cent, two pounds staked counts as one pound towards the requirement, which doubles the turnover needed and roughly doubles the expected cost.
Can free-spin winnings expire before the wagering is finished?
Yes, and there are usually two separate deadlines. One is the life of the spins themselves, which is the date by which they must be played. The other is the period allowed to complete the play-through on anything they win, which starts when the winnings are credited. Missing the second forfeits the bonus balance and whatever remains attached to it, which is why the two dates are worth reading as two dates.
