The moment a bonus stops being free money
You claim a promotion, the credit lands in your account, and the first thing you see is a balance that looks like cash. It is not cash yet. What you have received is a conditional promise: the operator will consider converting some of that balance into withdrawable funds only after a series of requirements are met, and only up to a stated limit. The entire craft of evaluating a promotion is reading those conditions before you opt in, because once you accept the bonus, you have accepted its terms.
Bonus hunting, stripped of its mystique, is the practice of comparing those conditions across offers and choosing the ones where the arithmetic is least unfavourable. It does not make a negative-expectation game positive. What it does is prevent you from accepting a promotion that is mathematically impossible, or nearly impossible, to turn into money you can take out.
What the wagering requirement demands
A wagering requirement, also called playthrough, is a multiplier stating how much must be wagered before bonus-related funds can be withdrawn. It applies to the bonus amount, and sometimes to the deposit plus bonus together. The arithmetic is simple in structure: a 30x requirement on a 50-unit bonus means 1,500 units must be wagered. That figure is an example; the multiplier on any specific offer is printed in the promotion's terms.
The number matters because every wager you place carries a house edge. You are not simply moving 1,500 units around and then withdrawing it; you are exposing that amount to a game whose mathematical advantage stays with the operator on every bet. The larger the wagering requirement, the more times your bonus is exposed to that edge, and the lower the expected value of the promotion becomes. A bonus with a small headline amount and a low playthrough can be worth more than a large bonus with a high one.
Wagering requirements are not the only multiplier in the terms. Game weighting changes how much each wager counts toward the requirement. A slot spin might count in full, while a low-edge table game might count at a fraction, or not at all. The terms page lists the weighting for each game category.
Where the promotion can still trap you
Three other conditions do as much work as the wagering multiplier, and they are easier to miss because they are often buried in a collapsible section or a linked document.
A maximum-cashout cap is the ceiling on how much of the bonus-derived winnings can ever become withdrawable, no matter how well the playthrough goes. If the cap is low relative to the bonus, the promotion is structured so that most of a lucky run is simply removed at the end. The cap is a number; it is always stated, and it is always worth finding before you claim.
An expiry window is the period in which the wagering requirement must be completed. If the window is short, you must wager at a pace that may not suit your bankroll or your schedule. Once the window closes, the bonus and any winnings attached to it are typically removed. The expiry applies to the wagering period; some promotions also expire the bonus itself if it is not used at all.
Game restrictions are the third condition. A promotion may be valid only on specified titles, or may exclude certain games entirely. If the only games that count toward playthrough are high-volatility slots, the path to completing the requirement will be wilder than on a low-volatility title, even though the underlying RTP has not changed.
| Condition | What it controls | Where to find it |
|---|---|---|
| Wagering requirement | How much must be wagered before withdrawal | Promotion terms, usually as a multiplier |
| Game weighting | What fraction of each wager counts toward playthrough | Terms page, by game category |
| Maximum cashout | The ceiling on withdrawable winnings from the bonus | Promotion terms, often a fixed amount |
| Expiry window | How long you have to complete the requirement | Promotion terms, as days or a deadline |
| Game restrictions | Which titles are eligible or excluded | Terms page, as a list or category rule |
The arithmetic of a bonus, step by step
You can evaluate a promotion without trusting anyone's summary of it. The method is to work through the conditions in order and see what is left at the end.
Start with the bonus amount and the wagering multiplier. Multiply them to get the total wagering obligation. Then apply the game weighting to see how much real wagering that obligation represents on the games you intend to play. If the games you prefer count at only a fraction, the effective amount you must wager is higher than the headline figure.
Next, consider the house edge on those games. Every unit you wager is expected to lose a small percentage to the house over the long run. Multiply the total real wagering by that edge to estimate the expected cost of completing the requirement. That figure is an expectation, not a prediction: a short session can end far above or far below it, because variance dominates any small number of spins or hands.
Finally, compare the expected cost to the maximum cashout cap. If the cap is lower than the expected cost of completing the playthrough, the promotion is structured so that a typical run ends with nothing to withdraw. If the cap is higher, the promotion may still have value, but only as a way to play with a discount on the expected loss, never as a route to guaranteed profit.
Why a bonus is never a strategy
The phrase "bonus hunting" invites the idea that a skilled player can collect promotions and come out ahead. The mechanism says otherwise. A bonus changes the amount you have to wager and the ceiling on what you can withdraw; it does not change the house edge on the games you play. No sequence of bets, no choice of game within the eligible list, and no timing of your session removes the built-in advantage the operator holds on every wager.
What a bonus does change is the rate at which your bankroll is exposed to that edge, and the conditions under which you can stop. A promotion with a low wagering requirement and a high cashout cap lets you play longer for the same expected loss. A promotion with a high requirement and a low cap accelerates the expected loss while pretending to offer something free. The skill in evaluating a bonus is not in beating the games; it is in reading the terms and declining the offers that are structured against you.
Where loyalty and comp value come from
Casino loyalty programmes and comps are a different kind of promotion, because they are not claimed as a lump sum. They are earned continuously from tracked play, and their value is calculated from the same underlying arithmetic as a bonus, but in reverse.
The central concept is theoretical loss, sometimes called theo. It is an estimate of how much a player is expected to lose over time, derived from three inputs: the average bet, the number of decisions per hour, and the house edge on the game being played. As an example, suppose a player averages 10 units per hand at a game with a 2% house edge and plays 60 hands per hour. The theoretical loss for that hour is 10 multiplied by 60 multiplied by 0.02, or 12 units. That is labelled example arithmetic: the actual edge on any game is printed in its information panel, and the decisions-per-hour figure depends on the game and the pace of play.
The operator uses this theoretical loss figure to decide how much of it to return as comps, loyalty points, or tier progress. The return is always a fraction of the theoretical loss, never the whole of it, because the operator's edge is the revenue that funds the programme. A player who receives a free meal or a room discount has not beaten the house; they have received a small rebate on an expected loss that is larger than the rebate.
| Input | What it measures | Why it matters for comps |
|---|---|---|
| Average bet | The typical wager size per decision | Directly scales the theoretical loss |
| Decisions per hour | How many hands, spins or rolls occur in an hour | Faster play means more exposure per hour |
| House edge | The operator's mathematical advantage per wager | Varies by game and by bet type |
| Theoretical loss | Average bet times decisions times edge | The base from which comp value is calculated |
| Comp return | The fraction of theoretical loss returned as benefits | Always less than the theoretical loss itself |
Loyalty tiers add a layer on top of this. A tier is a status level that unlocks a stated set of benefits, and the qualification for each tier is usually expressed as a number of points earned over a period. The points themselves are earned at a rate set by the programme, and that rate is the link between your theoretical loss and your tier. A higher tier does not mean the games have become more favourable; it means the programme has decided to return a larger fraction of a larger expected loss.
How to read a promotion before you opt in
The practical method is a short checklist, and it works on any offer, from a no-deposit bonus to a loyalty multiplier weekend.
First, find the terms. Every legitimate promotion has a terms page or a linked conditions document. If you cannot find the wagering requirement, the game weighting, the cashout cap, and the expiry window, treat the offer as unreadable and decline it. A promotion whose conditions are not stated is not a mystery to be solved; it is an offer where the operator has chosen not to show you the arithmetic.
Second, run the numbers. Multiply the bonus by the wagering requirement, apply the game weighting for the titles you would play, and estimate the expected cost using the house edge on those titles. Compare that cost to the cashout cap. If the cap is below the expected cost, the promotion is a way to wager with a ceiling on your upside and no floor on your downside.
Third, check the expiry. A wagering requirement you cannot complete within the window is a requirement you will fail, and failing it means the bonus and its winnings are removed. Choose promotions whose windows fit the pace at which you play, not the pace at which you imagine you might play during a lucky streak.
Fourth, and this is the part most often skipped, ask what the promotion is doing to your behaviour. A bonus that requires you to wager more than you would otherwise wager is not a discount; it is an inducement to increase your exposure. The operator is not offering the bonus out of generosity. It is offering the bonus because the expected value of the extra wagering, multiplied by the house edge, is worth more than the cost of the promotion. The terms are the operator's way of making sure that remains true.
FAQ
Can you make a living from bonus hunting?
No. A bonus changes the amount you must wager and the ceiling on what you can withdraw, but it does not change the house edge on the games themselves. Over any large number of promotions, the expected loss from the wagering requirement will exceed the value of the bonuses, because the operator has set the terms to ensure that outcome.
Why do some games count less toward wagering?
Game weighting exists because different games have different house edges and different rates of play. A game with a low house edge gives the operator less expected revenue per unit wagered, so the operator discounts its contribution to the playthrough requirement. The weighting table is the operator's way of equalising the expected cost of the bonus across game types.
What happens if I withdraw before completing the wagering requirement?
The operator's terms will state the consequence, which is typically the removal of the bonus and any winnings derived from it. Some operators also lock the deposit portion until the requirement is met or the bonus is forfeited. The exact rule is in the promotion terms, and it is worth reading before you claim, because the forfeiture rule determines what you are risking by accepting the bonus in the first place.
