Start with the claim screen, not the offer banner
Most promotional offers are advertised by their headline number, but the number that decides whether the offer is worth taking is usually printed much smaller. That smaller print is normally on the claim screen itself, or in a terms section linked from it, and it is the only reliable statement of what you are accepting. Before you click anything, look for four specific items: the wagering requirement, the game weighting table, the maximum-cashout cap, and the expiry window. If any of those four is missing or vague, treat the offer as unreadable until you find the full terms.
Claiming itself is usually a short process: you open the promotion, press the claim or opt-in button, and the credit appears in your account as either a cash balance or a separate bonus balance. The important part is what happens after that, because the credit is rarely withdrawable on arrival. What you do in the next hour or the next week determines whether any of it ever becomes money you can take out.
What a wagering requirement does
A wagering requirement, sometimes called playthrough, is a multiplier that states how much total money must be staked before bonus-related funds can be withdrawn. It is the central mechanism of almost every casino promotion. The arithmetic is simple enough to run in your head once you know the two inputs: the bonus amount and the multiplier.
Suppose a promotion grants 50 units of bonus credit and attaches a 30x wagering requirement. The total amount you must stake before withdrawal is 1,500 units. That does not mean you need to deposit 1,500 units, and it does not mean you will have 1,500 units at the end. It means the sum of every bet you place, win or lose, must reach that figure while the bonus is active. You could reach it by staking 15 units a hundred times, or 150 units ten times.
This is where the house edge does its quiet work. Every wager placed carries a built-in mathematical advantage for the operator, so the expected cost of generating 1,500 units of turnover is not zero. The requirement is not a hurdle you clear and then collect the full bonus; it is a period during which the game's normal expected loss applies to every spin or hand. A bonus with a high multiplier can cost more in expected loss than the headline credit is worth, which is why the multiplier alone never tells you whether an offer is good.
Game weighting changes how fast you clear the requirement
Not all wagers count equally toward playthrough. Most operators apply a weighting table, and it is usually the second thing you should read after the multiplier. A slot spin might count 100% of its stake toward the requirement, while a blackjack hand or a roulette bet might count only a small fraction, or nothing at all. Some games are excluded entirely, and playing them while a bonus is active can void the promotion.
The reason is structural. Games with a lower house edge, such as certain table games under favourable rules, give the player less expected loss per unit staked. If those games counted fully toward playthrough, a player could clear a requirement while losing less on average, which changes the economics of the promotion for the operator. Weighting is the operator's way of keeping the promotion's cost predictable.
Read the weighting table before you choose what to play. If a game counts 10% toward the requirement, then staking 100 units on it advances your playthrough by only 10 units. That means you need ten times as much total action on that game to clear the same bonus as you would on a fully weighted game. The practical effect is that the games you want to play may not be the games that clear the bonus efficiently.
| Term | What it controls | What to check before claiming |
|---|---|---|
| Wagering requirement | Total stake needed before withdrawal | The exact multiplier and whether it applies to bonus only or bonus plus deposit |
| Game weighting | How much each wager counts toward the requirement | Which games count fully, partially, or not at all |
| Maximum cashout | The upper limit on withdrawable winnings from the bonus | Whether a cap exists and what it is |
| Expiry window | How long you have to meet the requirement | The deadline and whether unused bonus funds are removed after it |
Cashout caps put a ceiling on the headline
A maximum-cashout cap is a limit on how much of the money generated from a bonus can ever be withdrawn, regardless of how well you play. A promotion might advertise 100 units of bonus credit, but if the cap is 50 units, then even a lucky run that produces 500 units of withdrawable balance will be reduced to the cap when you request a withdrawal. The rest is removed.
Caps are most common on no-deposit bonuses and free-spin offers, where the operator is giving away credit without requiring any deposit in return. The cap is the operator's way of bounding the cost of that giveaway. It is not hidden, but it is often the last term people read, and it changes the value of the offer completely. A no-deposit bonus with a 10-unit cap is a small fixed-value token, not a genuine chance at a large win, no matter what the advertised number says.
Free spins work the same way. The spins themselves are granted at a fixed stake on specified slot titles, and the winnings from those spins are commonly credited as bonus funds rather than withdrawable cash. Those funds then carry their own wagering requirement and their own cap. The chain matters: the spin produces a bonus balance, the bonus balance must be wagered, and the wagering result is subject to the cap.
Expiry is a deadline, not a suggestion
Every bonus carries an expiry window, and it is often shorter than people expect. The window is the period during which the wagering requirement must be met. If the deadline passes, the bonus funds and any winnings derived from them are typically removed from the account. Some operators also remove the bonus if you request a withdrawal before the requirement is complete, or if you play an excluded game, or if you simply stop playing for longer than the window allows.
The expiry window interacts with the wagering requirement to create a pace. A 30x requirement on a 50-unit bonus requires 1,500 units of staking. If the window is seven days, that is a little over 214 units of staking per day. Whether that pace is reasonable depends on your own session habits and the games you intend to play. A requirement that is mathematically clearable but practically unreachable inside the window is not a real offer; it is a retention device.
Check the expiry before you claim, not after. Once the clock starts, it rarely pauses, and missing the deadline forfeits the bonus balance without any refund of the stakes you placed while trying to clear it.
Where loyalty value comes from: theoretical loss
Loyalty and comp programmes operate on a different logic from a one-off bonus, but they use the same underlying mathematics. A casino does not reward you for winning or losing in the short run. It rewards you for the amount of theoretical value your play represents, because that is what the house edge turns into revenue over time.
The concept is called theoretical loss, and it is built from three inputs: your average bet size, the number of decisions or spins you make per hour, and the house edge on the specific game you are playing. As an example, suppose a player averages 5 units per spin on a game with a 2% house edge and plays 60 spins an hour. The theoretical loss per hour is 5 times 60 times 0.02, or 6 units per hour. That is not what the player will lose in any given hour; it is the long-run average across many hours of identical play.
Loyalty programmes track your play and convert that theoretical value into points, tier progress, or comp offers. A game with a higher house edge generates more theoretical loss per unit staked, so it tends to earn loyalty credit faster than a lower-edge game, even if the player's actual results are identical. This is why the same hour of play can earn very different loyalty value on different games. The programme is not rewarding your luck; it is rewarding the expected value your play represents to the operator.
The practical reading is simple: loyalty value is a rebate on expected loss, not a payment for your time. A comp worth 2 units costs, on average, far more than 2 units of expected loss to earn. The programme is designed so that the operator retains a margin after all rewards are paid. Treat comps as a small offset to the cost of play you would have made anyway, never as a reason to play more than you intended.
Before you opt in: a reading order
When you are looking at a specific claim offer, read the terms in this order. First, the wagering requirement and whether it applies to the bonus alone or to the bonus plus your deposit. Second, the game weighting table, so you know which games count and at what rate. Third, the maximum cashout, so you know the ceiling on what the bonus can become. Fourth, the expiry window, so you know the pace required. Fifth, any game restrictions or excluded titles that could void the promotion if you play them.
Only after all five are clear should you decide whether to claim. The claim button is the easy part. The terms are the offer. If the terms are not published in full, or if you cannot find the weighting table or the cap, the sensible move is not to claim until you can. A promotion you cannot read is a promotion whose value you cannot calculate, and the operator has already calculated it.
FAQ
Do I need to enter a code to claim a bonus?
Some promotions require a bonus code entered on the claim screen or during deposit, while others are claimed with a single button or credited automatically. The claim screen for the specific offer will state which method applies, and the code, if one exists, will be shown there or in the promotional message itself. Codes are case-sensitive in some systems, so enter them exactly as displayed.
Can I withdraw my deposit before meeting the wagering requirement?
Usually not without consequences. Most operators treat a withdrawal request made before the requirement is complete as a cancellation of the bonus, which removes the bonus balance and any winnings derived from it. Your original deposit is normally returned, but the promotional value is forfeited. The exact rule is in the promotion's terms under a heading such as bonus cancellation or withdrawal before playthrough.
Why did my bonus disappear before the expiry date?
The most common reasons are playing a game that is excluded from the promotion, placing a bet type that is not allowed while a bonus is active, or requesting a withdrawal before the requirement was met. Some operators also remove a bonus if the account goes inactive for a set number of days. The terms page for the specific promotion lists the void conditions, and the cashier or account history screen usually shows which event triggered the removal.
