Bonus cash starts as a balance you cannot withdraw
When a sportsbook or casino credits bonus cash to your account, the first thing to understand is that it is not money. It is a promotional balance with a set of conditions attached, and those conditions decide whether any part of it ever becomes withdrawable cash. The screen will show a number, but that number is best read as a claim ticket, not a bank balance.
The mechanics are consistent across most operators, even though the specific figures differ. A promotion grants a credit. Before that credit can be withdrawn, you must wager some multiple of it. While you are wagering, different games count toward that requirement at different rates. A cap limits how much of the resulting balance can ever leave the account. An expiry clock runs over the whole thing. Each of those pieces is worth reading before you opt in, because the headline number almost never survives contact with the terms.
The wagering requirement is the core mechanic
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sometimes called playthrough, is a multiplier stating how much must be wagered before bonus-related funds can be withdrawn.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 construct from whatever figure an operator prints. If a promotion carries a 30x requirement on a 50-unit bonus, then 1,500 units must be wagered before the bonus balance and any winnings attached to it become eligible for withdrawal. That is example arithmetic, not a universal figure: the multiplier and the bonus size are printed in the promotion's own terms, and they vary from offer to offer.
What matters is not the wagering total by itself but how fast the underlying game consumes your balance while you chase it. Every wager carries an expected loss, because the house edge applies to each unit you put in play. A large wagering requirement means you will, on average, lose a predictable share of your own deposited funds while trying to convert the bonus. The requirement is not a hurdle you clear and then collect; it is a volume of betting, and volume of betting is exactly where the house's mathematical advantage does its work.
Game weighting changes how much each wager counts
Not every wager contributes equally toward the playthrough total. Operators assign a weighting percentage to each game category, and the weighting is usually printed in the promotion's terms. A slot spin might count at 100% of its value, while a blackjack hand or a roulette spin might count at a materially lower percentage, or not at all. The reason is structural: the house edge differs by game, and the operator sets weightings so that the expected cost of clearing the bonus is roughly similar no matter what you play.
Here is how the same wagering requirement can feel very different depending on where you play it. Suppose a promotion requires 1,500 units of wagering. On a game weighted at 100%, every unit you wager counts as a unit, so you need to put 1,500 units through the game. On a game weighted at 10%, only one-tenth of each wager counts, so you would need to put 15,000 units through before the requirement is met. The printed multiplier is only half the story; the weighting table is the other half.
| Mechanic | What it controls | Where to find the figure |
|---|---|---|
| Wagering requirement | Total amount that must be wagered before withdrawal | Promotion terms, usually expressed as a multiplier |
| Game weighting | What share of each wager counts toward that total | Promotion terms, usually a table by game category |
| Maximum cashout cap | The ceiling on how much of the bonus balance can be withdrawn | Promotion terms, often in the fine print |
| Expiry window | How long you have to meet the requirement | Promotion terms or the bonus balance screen |
Maximum-cashout caps put a ceiling on the prize
Even if you meet the wagering requirement in full, the promotion may still not pay out everything sitting in your bonus balance. Many offers carry a maximum-cashout cap, a fixed ceiling on how much of the bonus-derived balance can ever be withdrawn. Any amount above the cap is simply removed when you request a withdrawal. The cap is a number, and it is printed in the terms, but it is frequently the last thing a player notices.
The cap interacts with the wagering requirement in a way that is easy to misread. A high wagering requirement does not mean a high potential payout; it means a high volume of betting before you can withdraw anything. A low cashout cap means that even a lucky run during the playthrough period will be truncated. The two figures together define the realistic ceiling of the promotion, and neither is optional reading.
Expiry windows turn the promotion into a timed exercise
Bonus cash does not sit in an account indefinitely. Every promotion carries an expiry window, a period of time in which the wagering requirement must be met. If the clock runs out first, the bonus balance and any winnings derived from it are removed. The window is usually stated in days and starts from the moment the bonus is credited, not from the moment you first use it.
An expiry window changes the practical meaning of a wagering requirement. A requirement that is easy to clear over a month becomes difficult over a weekend, because you would need to concentrate a large volume of betting into a short period. That concentration raises the variance you experience: with fewer bets, the short-run outcome can swing much further from the long-run average. The expiry window is therefore not just a deadline; it is a variance amplifier.
Loyalty and comp programmes work on a different clock
Bonus cash is a one-time promotional credit. Loyalty and comp programmes are a separate system that assigns value to tracked play over time, and the value is calculated from a concept called theoretical loss. The idea is that a venue or operator can estimate, before you ever place a bet, roughly how much your play is worth to them, because the house edge on each game is known.
The arithmetic is a chain of three factors. Average bet size is how much you wager per spin or hand. Decisions per hour is how many spins or hands you play in that hour. House edge is the mathematical advantage the operator holds on that specific game. Multiply the three together and you get a theoretical loss per hour. As a labelled example, suppose a player averages 2 units per spin on a slot, plays 600 spins per hour, and the game carries a 5% house edge. The theoretical loss is 2 times 600 times 0.05, or 60 units per hour. That is example arithmetic built from hypothetical inputs; the actual figures for any game are in its information panel or rules page.
Comps and loyalty points are typically awarded as a fraction of that theoretical loss, not as a fraction of what you won or lost in a given session. The distinction matters. Two players can have very different nights at the same table, but if their average bet and pace are similar, the programme values them similarly, because the programme is built on expectation, not outcome.
| Factor | What it measures | Why it matters for comps |
|---|---|---|
| Average bet | Your typical wager per spin or hand | Directly scales the theoretical loss |
| Decisions per hour | How fast you play | More volume means more theoretical loss in the same session |
| House edge | The operator's mathematical advantage on that game | Different games produce different theoretical loss at the same bet size |
| Theoretical loss | Average bet times decisions per hour times house edge | The basis on which comp value is typically awarded |
How to read a promotion before you opt in
The practical skill is not memorising any particular operator's numbers, because those change constantly and differ by jurisdiction. The skill is knowing which four figures to look for and how they interact. Open the promotion's terms and find the wagering requirement, the game weighting table, the maximum-cashout cap, and the expiry window. Read them in that order, because each one constrains the next.
Then do the arithmetic yourself, with the operator's printed figures in place of the example numbers above. Compute the total wagering required. Adjust it by the weighting of the game you intend to play. Compare the realistic cashout ceiling against the volume of betting you would need to do. Check whether the expiry window makes that volume realistic for your schedule. None of this tells you whether you will win or lose; it tells you what the promotion is offering, which is a different question entirely.
One more point deserves emphasis. No betting pattern changes the built-in edge of a negative-expectation game. A wagering requirement is not a puzzle that a clever sequence of bets can solve; it is a volume target, and volume of betting is where the house edge operates. Progression systems that double bets after losses redistribute outcomes, but they do not remove the edge. The promotion is worth taking only if the value of the entertainment, plus whatever the bonus realistically converts to, is worth the expected cost of the wagering you must do. That is a personal judgement, and the terms give you the inputs to make it.
FAQ
Why does my bonus balance show one number but my withdrawable balance shows another?
Because the two balances are separate ledgers. The bonus balance is promotional credit subject to wagering requirements, game restrictions, caps and expiry. The withdrawable balance is cash that has already cleared those conditions. The gap between them is the work the promotion still requires before the bonus side can move across.
Do all games count equally toward clearing a bonus?
No. Most promotions include a weighting table that assigns a different contribution percentage to each game category. Slots often count at full value, while table games and video poker may count at a fraction, or not at all. The weighting table is part of the promotion's terms and should be read before you start playing.
Is bonus cash the same as loyalty points or comps?
No. Bonus cash is a one-time promotional credit with its own wagering, cap and expiry terms. Loyalty points and comps are awarded on an ongoing basis from tracked play, typically as a fraction of theoretical loss rather than actual loss. The two systems run on different clocks and different arithmetic.
