The Screen That Matters More Than the Offer
Most players decide on a bonus by looking at the headline number. The smarter move is to ignore that number until you have read the terms screen, because the headline is the part the operator controls and the terms are the part that decides whether any of the credit ever becomes money you can take out. A bonus is not a gift sitting in your account. It is a conditional contract, and the conditions are written in four places: the wagering requirement, the game weighting table, the maximum-cashout clause, and the expiry window.
When you search for how to use a specific casino's bonus, the honest answer is that the mechanism is the same everywhere, but the numbers are not. Your operator's own promotion page and terms document carry the figures that apply to you. What follows is how to read those figures so you know what you are accepting.
Wagering Requirements as a Multiplication Problem
A wagering requirement, sometimes called playthrough, is a multiplier that states how much total wagering must happen before bonus-related funds can be withdrawn. The arithmetic is simple multiplication, but the inputs are easy to misread. If a bonus is subject to a requirement stated as a multiple of the bonus amount, you multiply the bonus by that multiple to get the total wagering target. Some operators apply the multiplier to the bonus plus the deposit that triggered it, which produces a much larger target from the same headline number. The terms screen tells you which base is used.
As an example only, suppose a promotion grants 50 units of bonus credit with a 30x requirement applied to the bonus alone. The wagering target is 1,500 units. If the same 30x applied to a 50-unit bonus plus a 50-unit deposit, the target doubles to 3,000 units. The difference is entirely in the terms, not in the size of the bonus. Before you claim anything, find the sentence that says what the multiplier applies to.
Wagering is not the same as losing. You are not required to lose the bonus amount; you are required to put a stated volume of money through the games. Because every wager carries a house edge, the expected cost of meeting the requirement is the wagering target multiplied by the edge on the games you play. That expected cost is the real price of the promotion.
Game Weighting Changes the Effective Requirement
Most promotions do not count every wager equally toward the playthrough target. A weighting table assigns each game category a contribution percentage. A slot might count fully toward the requirement, while a table game might count a smaller fraction, and some games may count nothing at all. When a game counts less than fully, the effective wagering requirement on that game is higher than the printed multiplier.
Suppose a requirement is 30x and a particular table game is weighted at a fraction of a slot's contribution. To clear the same target on that table game, you must wager proportionally more than the printed total. The terms page lists the weighting for each game category, and this table matters more than the headline multiplier because it determines where you can realistically clear the bonus.
| Term element | What it controls | Where to find it |
|---|---|---|
| Wagering multiplier | Total wager volume required before withdrawal | Promotion terms, usually near the top |
| Multiplier base | Whether the multiplier applies to bonus only or bonus plus deposit | Same clause as the multiplier |
| Game weighting | How much each game category contributes per unit wagered | Weighting table within the terms |
| Maximum cashout | The ceiling on withdrawable winnings from bonus play | Cashout or withdrawal clause |
| Expiry window | How long you have to meet the requirement | Validity or expiry clause |
Weighting is not a minor detail. A bonus that looks generous on slots can become nearly impossible to clear on the games you want to play, and playing a zero-contribution game while a bonus is active can waste time and sometimes void the promotion entirely. Read the weighting table before you make a single wager.
Maximum-Cashout Caps and Why They Exist
A maximum-cashout clause sets a ceiling on how much of the bonus-derived winnings can ever be withdrawn. Any amount above the cap is removed when you request a withdrawal, regardless of how much you wagered or how much the balance shows on screen. The cap is a risk-control tool for the operator, and it changes the expected value of the promotion dramatically.
The cap matters most on bonuses with no deposit attached, because those promotions expose the operator to players who clear the requirement and withdraw. The cap is stated in the terms as a fixed amount or as a multiple of the bonus. Your own operator's terms page carries the number. What you need to know is that the cap exists and that it applies to withdrawable winnings, not to the wagering target. A large wagering target combined with a small cap can make a promotion mathematically pointless even if everything else looks favourable.
Expiry Windows and the Clock You Cannot Pause
Every bonus has a validity period. If the wagering requirement is not met within that window, the bonus and any winnings derived from it are removed. The window is usually stated in days from the moment the bonus is credited, and it does not pause while you are not playing. This interacts with the wagering target: a high multiplier with a short window may require a volume of play per day that is impractical for most sessions.
Some promotions also impose a separate expiry on free spins, which may expire before the winnings from those spins do. The terms screen splits these clocks. Read both. The expiry window is not a suggestion, and support staff are generally not able to extend it after the fact.
Where Loyalty and Comp Value Comes From
Loyalty programmes and comps look like a different topic, but they are built from the same arithmetic as bonuses. A comp is not a reward for loyalty in the emotional sense. It is a partial rebate of the theoretical loss the venue expects from your play. Theoretical loss is a calculation, not an amount you necessarily lost: it is your average bet multiplied by the number of decisions you make per hour, multiplied by the house edge on the game you are playing.
As an example, suppose you play a game with a house edge of 2 percent, at an average bet of 10 units, and you make 60 decisions per hour. The theoretical loss for that hour is 10 times 60 times 0.02, which is 12 units. The venue might return a fraction of that amount as a comp or loyalty credit. The fraction is set by the venue and is not something you can calculate from the outside; the point is that the comp is funded by the edge, not by the venue's generosity.
This is why tracked play matters. If your play is not tracked because you are not using a card or because the game is excluded from tracking, the venue has no record of your theoretical loss and no basis for a comp. The loyalty screen in your account shows the balance the venue has calculated, and that balance is the product of this arithmetic, not a count of how much you deposited or how long you sat at the machine.
Comparing Bonuses Without a Spreadsheet
You do not need to calculate expected value to the decimal to evaluate a promotion. You need to compare four numbers against each other and against your own habits. First, the wagering target after weighting: how much do you have to wager on the games you play? Second, the maximum cashout: is the ceiling high enough that clearing the bonus is worth the time? Third, the expiry window: can you realistically meet the target in the time allowed? Fourth, the expected cost of the wagering, which is the target multiplied by the house edge on the games that count.
A promotion that fails any one of these tests is not worth claiming, regardless of the headline amount. A promotion that passes all four is still not free money; it is a discounted way to play, and the discount is paid for by the variance you accept along the way. The terms screen is the only place where all four numbers appear together, and it is the only screen you should trust.
FAQ
Does a bonus change the house edge on the games I play?
No. The house edge on a game is fixed by the game's rules and payout structure. A bonus changes the amount you must wager and the conditions attached to withdrawing, but it does not alter the edge on any spin or hand. The expected cost of clearing a bonus is the wagering target multiplied by that unchanged edge.
Why did my bonus balance disappear after I met the wagering requirement?
The most common reasons are an expired window, a game you played that was excluded or zero-weighted, or a maximum-cashout cap that removed the excess above the ceiling. The terms screen records all three. Check the weighting table first, because a zero-contribution game can void a bonus even when the balance on screen still looks healthy.
Are no-deposit bonuses ever withdrawable?
They can be, but only after the conditions are met. A no-deposit bonus is normally subject to the same wagering requirement, game weighting, cashout cap and expiry window as any other promotion, and the cap is often the binding constraint. The terms page states the cap and the requirement; if the cap is low relative to the wagering target, the promotion may not be worth the time even though it costs nothing to claim.
