Start with the number that decides whether a promotion is worth your time
Most players look at a slot promotion and see the headline figure: the bonus amount, the free spins count, the prize pool. The number that determines whether the promotion has any value sits further down the page, in a block of terms usually labelled something like “Bonus rules” or “Promotional terms”. That block contains the wagering requirement, the game weighting table, the maximum-cashout cap and the expiry window. Read those four things before you opt in, and the promotion stops being a mystery.
A wagering requirement is a multiplier stating how much must be wagered before bonus-related funds can be withdrawn.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. What makes it complicated is that not every wager counts equally toward that total, and that is where game weighting enters.
Game weighting decides how fast a requirement clears
Game weighting is a set of percentages the operator applies to different game categories when calculating how much of each wager counts toward the playthrough total. A slot spin might count at 100% of its stake, while a table game wager might count at a smaller share, or not at all. The operator publishes this table inside the promotion terms, and it changes the effective size of the requirement.
If a game counts at 100%, a 100-unit wager moves the requirement by 100 units. If a game counts at 20%, the same 100-unit wager moves it by only 20 units. The requirement has not changed; the rate at which your play satisfies it has. A promotion that looks identical on the headline can clear five times slower depending on which games you play.
| Term element | What it states | Why it matters to you |
|---|---|---|
| Wagering requirement | The multiplier applied to the bonus amount | Sets the total wagered volume before withdrawal is possible |
| Game weighting | The percentage of each wager that counts, by game type | Changes the effective speed and cost of clearing the requirement |
| Maximum cashout | The upper limit on how much of the bonus-derived balance can be withdrawn | Caps the realisable value even if the requirement is met |
| Expiry window | The time allowed to complete the requirement | Forces a pace of play; lapsing forfeits the bonus funds |
Weighting matters most when the promotion is attached to slots but the terms allow other games. A player who drifts to blackjack or roulette while a slot bonus is active may find their progress slows dramatically, because the weighting table treats those categories differently. The fix is not to avoid those games forever; it is to know the table before you start.
The cashout cap is the quiet ceiling on every promotion
A maximum-cashout cap is the upper limit on how much of a bonus-derived balance can ever become withdrawable. It applies even after the wagering requirement is fully met. If a promotion carries a cap, any balance above that figure is removed at the point of withdrawal, regardless of how the play went.
This changes the promotion’s shape. Without a cap, the value of a bonus is bounded mainly by the requirement and the games. With a cap, the value is bounded absolutely. A large headline bonus with a small cap and a heavy requirement may be worth less than a modest bonus with no cap and a light requirement, because the cap truncates the upside before the requirement has even begun to bite. The cap is stated in the promotion terms, usually as a fixed amount, and it is one of the first things to check.
Expiry windows turn value into a pacing problem
Most promotions carry a time limit. The wagering requirement must be completed within that window, or the bonus funds and any winnings derived from them are removed. The window is stated in the terms, and it interacts with the requirement to produce a required pace of play.
As an example, suppose a promotion requires 1,500 units of wagering and allows seven days. That is a little over 214 units per day on average. Whether that pace is comfortable depends on your stake size and session length, not on the promotion’s marketing. A short window on a large requirement favours high-stakes play, which also means larger swings in either direction. A long window on a small requirement is easier to complete without changing your normal habits. Neither fact makes the promotion good or bad; it makes it suited or unsuited to how you already play.
Free spins are a bonus format, not a bonus amount
Free spins are spins granted at a fixed stake on specified slot titles. The phrase sounds like cash, but the mechanism is usually different: winnings from free spins are commonly credited as bonus funds subject to wagering requirements rather than as withdrawable cash. The stake is fixed by the operator, the games are specified in the terms, and the winnings inherit the same requirement, cap and expiry structure as any other bonus.
This means a batch of free spins has a calculable maximum raw value—the number of spins times the fixed stake—but the realisable value is determined by the terms attached to the winnings. A player evaluating free spins should read them as a conditional entry into the same promotional structure, not as a cash equivalent.
Loyalty value is built from tracked play, not from generosity
Loyalty and comp programmes work on a different principle from bonuses. A bonus is a fixed offer with stated terms. A loyalty programme is a running calculation based on your tracked play, and the value it returns is tied to a concept called theoretical loss.
Theoretical loss is the expected value of your play over time, calculated from three inputs: average bet, decisions per hour, and house edge. As an example, suppose a player averages 2 units per spin on a slot, plays 400 spins in an hour, and the game has a 4% house edge. The theoretical loss for that hour is 2 times 400 times 0.04, which is 32 units. That is not what the player lost; it is the long-run expectation of the play. The loyalty programme typically returns a small share of that theoretical figure as points, comps or tier progress.
Because the calculation uses house edge, the same wagered volume produces different theoretical loss on different games. A slot with a higher house edge generates more theoretical loss per unit wagered than a table game with a lower edge, which is why loyalty programmes often treat game categories differently. The programme terms state the earning rate, the game categories and any exclusions.
What you control, and what you do not
You control which promotions you accept, which games you play while a requirement is active, the pace of your sessions, and when you stop. You do not control the house edge on the games, the weighting table, the cap or the expiry window. Those are set by the operator and published in the terms.
The practical skill is reading the terms in the right order: requirement first, then weighting, then cap, then expiry. That order converts a block of legal text into a small set of numbers you can compare across promotions. A promotion is not good because it is large and not bad because it is small. It is good or bad relative to the requirement it imposes, the games it allows, the ceiling it sets and the time it gives you.
FAQ
Does game weighting apply to the bonus amount or to the wagers?
Game weighting applies to the wagers you make while the requirement is active. Each wager counts toward the requirement at the percentage assigned to the game category. The bonus amount itself is fixed; weighting changes how quickly your play satisfies the multiplier.
Can a maximum-cashout cap be removed by playing more?
No. The cap is a term of the promotion, not a function of your play. Meeting the wagering requirement makes the bonus-derived balance eligible for withdrawal, but any amount above the stated cap is removed at that point regardless of how much was wagered or won.
Why do loyalty programmes return more for some games than others?
Because the programme is built on theoretical loss, and theoretical loss depends on house edge. A game with a higher house edge produces a larger expected loss per unit wagered, so the programme can afford to return a larger share on that game while keeping the same underlying calculation. The earning rates by game category are published in the programme terms.
