How a Sportsbook's 300 Bonus Is Built and Read

A promotional credit on a sportsbook app is never just the headline number. This explains the wagering, caps, expiry and weighting rules that decide what a bonus is worth before you opt in.

The number in the ad is not the number in your account

A sportsbook app advertises a promotional credit with a headline figure, and the reader's first question is usually whether that figure is cash. It is not. What the operator is offering is a conditional claim: a balance that becomes withdrawable only after a chain of rules is satisfied. The figure in the promotion is the starting input, not the ending balance. Reading the offer means working backwards from that headline to the terms that sit underneath it.

Every promotional credit of this kind is governed by the same set of moving parts, and each part changes what the offer is worth. The wagering requirement states how much total action must be placed before the bonus-related funds can be withdrawn. The maximum-cashout cap states how much of the resulting balance can ever leave the account. The expiry window states how long the player has to complete the playthrough. The game weighting states whether different wagers count fully, partially, or not at all toward that playthrough. None of these numbers is universal; each is printed in the offer's own terms, and the reader's job is to find that document and read it in this order.

Wagering requirement: the multiplier that defines the task

The wagering requirement, sometimes called playthrough, is a multiplier. It states how much must be wagered in total before bonus-related funds become withdrawable. The arithmetic is simple and the same sentence must always mark it as an example: a 30x requirement on a 50-unit bonus means 1,500 units of wagers must be placed. The reader's own offer will carry its own multiplier and its own bonus size, and those two numbers together define the size of the task.

What matters more than the multiplier is what counts toward it. An operator can state a playthrough figure and then quietly exclude entire categories of wagers from counting. A bet on one market may count in full, a bet on another may count at a reduced rate, and a bet on a third may count for nothing. This is game weighting, and it is the single most important table in the offer terms. A player who ignores weighting can believe they have completed the requirement when the operator's ledger says they have not.

ElementWhat it controlsWhere the reader finds their own figure
Wagering multiplierTotal wager volume required before withdrawalThe offer's terms section, stated as a multiple of the bonus
Game weightingHow much each wager counts toward the requirementThe same terms, usually a table by market or game type
Maximum cashoutThe ceiling on how much of the final balance can be withdrawnThe offer terms, sometimes under a separate cap heading
Expiry windowHow long the player has to complete the playthroughThe offer terms, stated in days or a fixed date
Eligible deposit or stakeWhether a qualifying action is required to trigger the bonusThe offer's landing page or registration flow

Maximum-cashout caps: the ceiling the ad does not mention

A maximum-cashout cap is a ceiling on how much of the post-playthrough balance can be withdrawn. It is separate from the wagering requirement. A player could complete the entire playthrough, finish with a balance larger than the cap, and still only be able to withdraw up to the cap. The rest is removed. This is why the headline figure and the real value of an offer can diverge so sharply: the cap, not the bonus size, often determines the best possible outcome.

The cap is always stated in the offer terms, though it may be buried in a paragraph rather than displayed beside the headline. The reader should locate it before opting in, because it changes the decision entirely. An offer with a generous headline and a low cap is a different proposition from one with a smaller headline and no cap at all. The only way to know which is which is to read the cap line and compare it against the playthrough size.

Expiry windows and the cost of running out of time

Every promotional credit carries an expiry window. If the playthrough is not completed within that window, the bonus funds and any winnings derived from them are typically removed. The window is a deadline, not a suggestion, and it interacts with the wagering requirement in a way that matters: the larger the required wager volume, the more sessions the player must fit inside the window. A short window on a large playthrough is a much harder task than a long window on a small one.

The expiry figure is printed in the offer terms, usually as a number of days from the moment the bonus is credited. The reader should note when the clock starts. Some operators start the window at credit, others at first use, and the difference can be material. The terms page is the only reliable source for both the length of the window and its start condition.

Game weighting: where the playthrough gets harder or easier

Game weighting is the operator's way of adjusting how much each wager contributes to the playthrough. A wager on one market might count at full value, while a wager on another counts at a reduced fraction, and a wager on a third counts for nothing. The weighting table is part of the offer terms, and it exists because different wagers carry different house edges and different variance profiles. The operator is not neutral about where the playthrough happens.

This is where the reader's own choices enter. A player who reads the weighting table can direct their playthrough toward the wagers that count fully and away from the ones that do not. That does not change the underlying mathematics of any bet; it only changes how efficiently the required volume is completed. The house edge on each wager remains whatever it is, and no weighting choice removes it. What the player controls is the speed and cost of satisfying the requirement, not the expected outcome of the wagers themselves.

Where loyalty and comp value comes from: theoretical loss

Separate from any promotional credit, a sportsbook or casino app also runs a loyalty or comp programme. These programmes are not gifts. They are a return of a small slice of the player's expected loss, calculated from tracked play. The concept the operator uses is theoretical loss, and it is built from three inputs: the average bet, the number of decisions per hour, and the house edge on the games being played.

The arithmetic is labelled as an example in every case, because the reader's own figures come from their own play and the operator's own edge tables. Suppose a player averages 10 units per bet, makes 60 bets per hour, and plays a game with a house edge of a stated percentage. The theoretical loss for that hour is the product of those three numbers. The operator's comp programme then returns some fraction of that theoretical loss as points, tier progress, or redeemable value. The fraction is set by the operator and printed in the programme's own terms.

InputWhat it measuresWhere the figure comes from
Average betThe typical stake per decision, averaged over a sessionThe player's own tracked play history
Decisions per hourHow many bets or hands are placed in an hourGame speed and the player's own pace
House edgeThe operator's mathematical advantage on each wagerThe game's published rules and paytable
Comp return rateThe fraction of theoretical loss returned as valueThe loyalty programme's own terms page

The key point is that comp value is not a reward for winning. It is a rebate on losing, calculated from the expected loss, not the actual result. A player who wins on a given night still generates theoretical loss, because the calculation uses the long-run edge, not the short-run outcome. The comp programme is therefore a way for the operator to encourage continued play while returning a controlled fraction of the expected loss. The player should read it as a discount on the cost of playing, never as a reason to play more.

Reading an offer before opting in: the order that matters

The reader who wants to evaluate a promotional credit should read the terms in a specific order, because each element constrains the ones that follow. Start with the wagering requirement and its multiplier. Then read the game weighting table to see which wagers count. Then read the maximum-cashout cap to see the ceiling on any withdrawal. Then read the expiry window to see how long the task takes. Only after all four are known does the headline figure mean anything at all.

This is not a moral judgement on the offer. It is a method. The same method applies to a no-deposit bonus, a free-spins grant, or a deposit-match credit: every one of them is a conditional claim, and every one of them is governed by the same four moving parts. The reader who learns to read those parts in order can evaluate any offer from any operator without ever relying on the advertising copy.

Why the headline exists and what it hides

The headline figure exists because it is the simplest possible statement of the offer, and simplicity is what draws attention. What it hides is everything that determines value. The wagering requirement, the weighting table, the cashout cap, and the expiry window are all printed somewhere, but they are printed in the terms, not in the ad. The gap between the two is where the reader's work happens.

No betting pattern, no choice of market, and no speed of play changes the built-in edge of a negative-expectation game. A promotional credit can change the arithmetic of a single session by adding conditional funds, but it does not change the mathematics of the wagers themselves. The player who understands this can take an offer for what it is: a set of conditions that may or may not be worth accepting, judged entirely by the terms that sit underneath the headline.

FAQ

Does the 300 bonus arrive as withdrawable cash?

No. A promotional credit of this kind is credited as bonus funds, not cash. It becomes withdrawable only after the wagering requirement is completed, and even then it is subject to the maximum-cashout cap and the expiry window printed in the offer terms.

Can I use the bonus on any market I want?

Only if the game weighting table allows it. Some markets count fully toward the playthrough, some count at a reduced rate, and some are excluded entirely. The weighting table is part of the offer terms and must be read before the first wager is placed.

Is a loyalty programme the same as a bonus?

No. A bonus is a one-time conditional credit with its own terms. A loyalty programme is an ongoing return of a fraction of theoretical loss, calculated from average bet, decisions per hour, and house edge. The two are governed by separate documents and should be evaluated separately.
