Bonus credit is a loan of playing time, not a deposit
When a casino adds bonus credit to your account, the balance on screen goes up. What does not go up is the amount you can withdraw. Bonus credit is promotional value with conditions bolted on, and those conditions decide whether any of it ever becomes real money. The first move is not to play with it. The first move is to read the terms attached to the specific offer, because two bonuses of the same size can be worth very different amounts.
Most bonus credit follows the same skeleton. You receive a balance marked as bonus funds. You wager it on eligible games. As you wager, the operator tracks how much total action you have put through. Only after that tracked action passes a threshold does the bonus portion convert into withdrawable cash. At any point before that, the bonus can disappear if you break a rule or let it expire.
What wagering requirements do to the balance
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sometimes called playthrough, is a multiplier stating how much must be wagered before bonus-related funds can be withdrawn.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 simple to build for any offer once you know the multiplier and the bonus amount. As an example: if a 30x requirement sits on a 50-unit bonus, you must wager 1,500 units before the bonus portion becomes withdrawable. That figure is not your target profit. It is the volume of bets you must push through the games.
Two things make this harder than the headline number suggests. First, your real-money balance usually plays first, with the bonus balance locked until the real funds are gone or the wagering is complete. Second, the requirement applies to wagers, not to wins. A spin that returns nothing still counts toward the requirement. A spin that wins does not count any more than a losing spin of the same size.
The practical consequence is that the expected cost of clearing a bonus is the wagering volume multiplied by the house edge on the games you are allowed to play. That cost is paid in the form of losses along the way. The bonus is worth something only if the remaining value after expected losses is positive, and that calculation changes with every offer.
Game weighting changes the real requirement
Game weighting is the rule that not all wagers count equally toward playthrough. A slot spin usually counts at 100 percent. A table game wager might count at a fraction of that, or not at all. The operator publishes a table of weightings inside the promotion terms, and that table is part of the offer's true cost.
If a game counts at 10 percent, then a 100-unit wager adds only 10 units toward the requirement. The requirement has effectively become ten times larger for anyone playing that game. The same logic works in reverse: a game weighted at 200 percent clears the requirement twice as fast. The weighting table is not a footnote. It is the difference between a bonus that clears in an afternoon and one that cannot realistically be cleared at all.
| Element | What it controls | Where to find it |
|---|---|---|
| Wagering multiplier | Total wager volume before withdrawal | Promotion terms, bonus details screen |
| Game weighting | How much each wager counts by game type | Terms table, often below the multiplier |
| Maximum cashout | Ceiling on withdrawable winnings from the bonus | Promotion terms |
| Expiry window | Time allowed to complete wagering | Terms, bonus balance display |
| Eligible games | Which titles may be played with bonus funds | Terms, sometimes enforced in the client |
Maximum-cashout caps and expiry windows
A maximum-cashout cap is a ceiling on how much of the bonus-derived winnings can ever be withdrawn. If a no-deposit bonus carries a cap, any balance above that cap is removed when the wagering completes. The cap applies even if you run the bonus up far beyond it. This is why a large bonus with a small cap can be worth less than a small bonus with no cap at all.
Expiry windows work the same way, but through time. A bonus that expires in a short window forces fast, high-volume play to clear it. A bonus with a 30-day window lets you spread the wagering across sessions. The expiry clock usually starts when the bonus is credited, not when you first use it. If the clock runs out, the bonus and any winnings derived from it are typically removed.
Both conditions are printed in the same terms block as the wagering requirement. Read them together, because they interact. A high wagering requirement with a short expiry window is effectively a bonus designed to expire before it clears. A low requirement with a long window and a high cap is the opposite.
How loyalty and comp programmes value your play
Loyalty credit is built on a different principle from a one-off bonus. A comp programme tracks your play over time and converts it into points, tier progress, or redeemable value. The operator is not giving you a promotional sum. It is returning a fraction of the mathematical value of your action.
The core concept is theoretical loss, sometimes called theo. It is not what you lost. It is the average amount the house expects to keep from your play given the games you choose and the volume you generate. The arithmetic is a labelled example, not a promise: average bet multiplied by decisions per hour multiplied by the house edge of the specific game you are playing. Suppose you average 5 units per hand at a table game with a house edge of 2 percent and play 60 hands per hour. The example theoretical loss is 5 times 60 times 0.02, or 6 units per hour. The actual hour will be higher or lower. Theoretical loss is a long-run average, not a session result.
Comps are typically a fraction of that theoretical number. A programme might return a small percentage of theo as points or credit. The exact return rate and the tier benefits are set by the operator and printed in the programme rules. What matters for evaluating the offer is that comps are not free money. They are a partial rebate on the expected cost of playing, and the expected cost is always positive on a negative-expectation game.
Two players with the same visible spend can earn very different comps because the games carry different edges. A slot player and a blackjack player betting the same amount per hour generate different theoretical losses, and the programme values them accordingly. The programme rules state the earning rate per game type. That table is the equivalent of game weighting in a bonus offer.
Reading an offer before you opt in
The way to evaluate bonus credit is to treat it as a conditional contract. The headline number is the least informative part. The terms decide what the offer is worth, and the terms are always published before you accept. The cashier or promotions page carries the full text. If a term is missing, ask support before opting in, because accepting the bonus usually locks the conditions in place.
Work through the same questions for every offer. What is the wagering multiplier? Which games count, and at what weighting? Is there a maximum cashout, and if so, what is it? How long does the clock run? Does the bonus sit behind your real balance or in front of it? The answers to those five questions describe the offer more accurately than the bonus amount ever will.
One final distinction matters. A deposit bonus and a no-deposit bonus carry the same structural conditions, but the no-deposit version is normally subject to tighter caps and shorter windows. Free spins winnings are commonly credited as bonus funds subject to wagering requirements rather than as withdrawable cash. None of these formats is inherently better or worse. Each is a set of conditions, and the conditions are what you are really accepting.
FAQ
Can I withdraw bonus credit immediately?
No. Bonus credit is locked until the wagering requirement attached to the specific offer is met, and even then a maximum-cashout cap may limit how much becomes withdrawable. The bonus balance display in your account shows the remaining wagering progress and the expiry clock.
Why does my bonus balance not go down when I bet?
Most operators structure bonus play so that real-money funds are used first, with the bonus balance remaining locked until the real balance is exhausted or the wagering requirement clears. The order is set out in the promotion terms, and it changes how the bonus behaves in practice.
Do comp points work the same way as bonus credit?
Not exactly. Bonus credit is a fixed promotional sum with wagering conditions. Comp points are earned from tracked play over time and are typically valued against your theoretical loss rather than against a wagering multiplier. The earning rate per game type is published in the loyalty programme rules.
