The offer that looks largest is rarely the one that pays
Two promotions can sit side by side on a casino's page, one advertising double the headline amount of the other, and the smaller one can still be the better deal. The advertised number is a ceiling, not a promise. What decides whether any of it can ever leave your account is a short list of conditions usually tucked behind a link labelled terms, conditions, or bonus policy. Before you opt in, you are not really choosing between bonus sizes. You are choosing between sets of rules.
This article walks through the four mechanisms that do most of the work in determining promotional value: wagering requirements, game weighting, maximum-cashout caps, and expiry windows. It also explains how loyalty and comp programmes value your play differently, using a concept called theoretical loss. No single bonus is named here, because the same structure applies across operators and jurisdictions, and the figures that matter are always printed on the offer itself.
Wagering requirements turn bonus money into locked money
A wagering requirement, sometimes called playthrough, is a multiplier stating how much must be wagered before bonus-related funds can be withdrawn. The arithmetic is straightforward: a 30x requirement on a 50-unit bonus means 1,500 units must be wagered. The practical meaning is less obvious. You cannot simply bet the bonus once and withdraw whatever remains. You must put the required total volume of action through qualifying games, and while you do, the house edge on those games is working against the balance.
This is why the requirement multiplier is the first number to check, but not the only one. A lower multiplier applied only to high-house-edge games can cost more in expected loss than a higher multiplier applied to low-edge games. The multiplier tells you how far you must travel. The game weighting tells you how expensive each step is.
Some promotions apply the requirement to the bonus amount alone. Others apply it to the bonus plus the deposit that triggered it. The difference is material, and the terms page states which one applies. Read that sentence before you read anything else in the offer.
Game weighting decides how fast your wagers count
Not every wager contributes equally toward clearing a wagering requirement. Operators assign different weightings to different game categories, and the weighting changes how much of each wager counts toward the target. A slot spin might count in full, while a blackjack hand or a roulette spin might count at a fraction, or not at all.
The reason is structural. Games with a lower house edge give the player a better expected result per unit wagered, so operators discount them when they are used to clear a bonus. Games with a higher edge, or games where skill cannot reduce the edge, are weighted more generously. The weighting is not a comment on the game's quality; it is a control on the promotion's cost.
This matters because the weighting changes the effective requirement. A 30x requirement on slots is one distance. The same 30x requirement, if table games count at a low weighting, is effectively a much longer distance when played on those tables. The comparison below shows what changes and what does not.
| Element | What it controls | Where it is stated |
|---|---|---|
| Wagering multiplier | Total volume of wagers required before withdrawal | Bonus terms page |
| Game weighting | What fraction of each wager counts toward that volume, by game category | Bonus terms or game contribution table |
| Eligible games | Which titles may be played at all while the bonus is active | Bonus terms |
| Maximum bet during playthrough | The largest single wager allowed while clearing the bonus | Bonus terms |
Some bonuses exclude entire categories. Playing an excluded game while a bonus is active can void the promotion and any winnings attached to it, so the eligible-games list is not a suggestion. It is part of the contract you accept when you opt in.
Cashout caps and expiry windows set the ceiling
A maximum-cashout cap is the largest amount that can be withdrawn from winnings generated by a promotion, regardless of how much the balance shows. A no-deposit bonus, for example, is normally subject to wagering requirements, maximum-cashout caps, game restrictions and expiry windows, which determine whether any of it can become withdrawable. If a promotion carries a cap, winnings above that figure are removed when the bonus is converted or when a withdrawal is requested. The cap is printed in the terms, and it applies even if the wagering requirement was completed honestly.
Expiry windows work the same way from the other direction. A bonus that is not used, or a wagering requirement that is not completed, within the stated window is forfeited along with any winnings derived from it. Some windows begin when the bonus is credited; others begin when the first wager is placed. The distinction matters, because a bonus claimed on a Friday and left untouched for a week may already be gone.
These two mechanisms are why the headline amount is not the value. A large bonus with a low cap and a short window can be worth less than a small bonus with no cap and a long window. The only way to compare two offers is to place their four core terms side by side: multiplier, weighting, cap, and window.
Loyalty and comp programmes value your play, not your deposits
Loyalty programmes and comps work on a different principle from sign-up bonuses. A sign-up bonus is a fixed promotional credit with fixed conditions. A comp is a return calculated from your tracked play, and its value depends on how much you wager, how fast you play, and which games you choose.
The central concept is theoretical loss. It is not what you lost in a session. It is an estimate of what the operator expects to earn from your action over time, calculated from three inputs: your average bet, the number of decisions you make per hour, and the house edge on the game you are playing. As an example, suppose a player averages 5 units per hand at blackjack, plays 60 hands per hour, and the house edge on that table under its specific rules is 1 unit per 100 wagered. The theoretical loss per hour would be 5 times 60 times 0.01, or 3 units per hour. That is the figure a comp programme uses to decide what your play is worth to the venue.
The same arithmetic explains why two players can sit at the same table for the same length of time and receive different offers. The player betting more per hand, or playing more hands per hour, generates more theoretical loss, and the programme responds accordingly. The player who lost more in a session has not necessarily generated more value; short-run results are not the same as the long-run average the programme is built on.
| Input | What it measures | Why it matters to the programme |
|---|---|---|
| Average bet | Typical wager size per decision | Scales theoretical loss directly |
| Decisions per hour | Speed of play, which varies by game and player | More decisions mean more total action |
| House edge | Mathematical advantage on the specific game and bet | Converts action into expected value for the operator |
| Session length | Total time at the table or machine | Multiplies the per-hour figure |
Comps are therefore not a reward for losing. They are a rebate on expected value, calculated from tracked play. A player who wins steadily but bets heavily may receive more in comps than a player who lost a small amount slowly. This is also why comp offers are not a reason to play longer or bet larger than you otherwise would. The comp is a fraction of the theoretical loss, not a recovery of it.
How to evaluate an offer before you opt in
The evaluation is a short sequence of checks, and every one of them is answered by a document the operator publishes. Start with the wagering requirement and what it applies to. Then read the game weighting table and the eligible-games list. Then find the maximum-cashout cap and the expiry window. Only after those four are known does the headline amount mean anything.
If any of those terms is missing or unclear, the offer is not better for being vague. It is just unreadable, and an unreadable offer is one you cannot value. The terms page is part of the promotion, not a footnote to it.
For loyalty and comp programmes, the equivalent document is the programme rules or the host desk's printed explanation. It states how play is tracked, how points or tier credits are earned, and what the redemption rates are. The value of a comp is never the retail price of the room or meal attached to it. It is what the programme's own published rates say your tracked play earned.
Where the numbers you need live
This article deliberately contains no bonus amounts, no wagering multipliers, no cashout caps and no tier benefits. Those figures are operator-specific and change constantly, and any number written here would be wrong for most readers by the time they read it. The reliable method is to read the offer's own terms page, which the operator is required to publish alongside the promotion, and to treat the headline as marketing until the terms confirm it.
The same applies to the question of which bonus is best. There is no best bonus in the abstract. There is only the bonus whose terms you have read and whose arithmetic you have accepted. A promotion that clears on games you would play anyway, with a requirement you can complete inside the window, is worth more to you than a larger promotion on games you would not otherwise touch.
No betting pattern changes the built-in edge of a negative-expectation game, and no bonus removes it. A bonus changes the starting balance and the withdrawal conditions; it does not change the mathematics of the games themselves. Progression systems that double bets after losses redistribute outcomes rather than remove the edge, and a bonus does not alter that. The value in a promotion is the value of its terms, read in full, before you opt in.
FAQ
What does a 30x wagering requirement mean?
It means the total amount you must wager before bonus-related funds can be withdrawn is thirty times the amount the requirement applies to. If the requirement applies to a 50-unit bonus, that is 1,500 units of wagering. Game weighting can change how much of each wager counts toward that total, so the effective requirement may be higher on some games.
Why do some games count less toward a bonus?
Games with a lower house edge give the player a better expected result per unit wagered, so operators discount them when they are used to clear a bonus. The weighting is a control on the promotion's cost, not a judgement on the game. The contribution table in the bonus terms states exactly what fraction each category counts.
How is a loyalty comp different from a sign-up bonus?
A sign-up bonus is a fixed promotional credit with fixed conditions. A comp is a return calculated from your tracked play, using theoretical loss: average bet times decisions per hour times house edge, as an estimate of the value your action generates. Comps are a rebate on expected value, not a reward for losing, and their rates are set by the programme's own published rules.
