A player opens Castrump's bonus page because they want the extra money or spins, but the page is not a menu of gifts. It is a menu of conditions, and the only question that matters is which condition makes the offer unwinnable. The bonus itself is never the thing being offered; what is being offered is a set of rules under which the bonus may, or may not, become withdrawable cash.
The four shapes a bonus takes, and what each one costs
Almost every offer on a casino bonus page falls into one of four mechanical shapes. Each shape looks different on the surface, but all of them are governed by the same underlying condition: the player must wager a stated multiple of some base amount before the bonus or its winnings can leave the account.
| Bonus shape | What the player receives | What it always costs | Where the cost is stated |
|---|---|---|---|
| Deposit match | Extra balance added after a deposit | A wagering multiple on the deposit, the bonus, or both | The offer's own terms block, usually below the headline |
| Free spins | A fixed number of spins on named games | Winnings from those spins are bonus funds, not cash | The same terms block, under a "free spins" subheading |
| Cashback | A return of a portion of losses over a period | Usually credited as bonus funds with their own playthrough | The cashback section of the bonus page or the general terms |
| No-deposit bonus | A small balance or spins without a deposit | The highest wagering multiple and the lowest withdrawal ceiling | A dedicated no-deposit terms section, if one exists |
The shape tells the reader what they are getting. It says nothing about whether they can keep it. A deposit match with a low headline percentage can be far more valuable than a no-deposit offer with a high one, because the no-deposit offer typically carries a wagering multiple several times higher and a cap on how much of the resulting balance can ever be withdrawn. The reader who compares percentages instead of conditions is comparing the wrong numbers.
How a wagering requirement is computed, and on what basis
A wagering requirement is a multiplication problem. The player must place bets whose total value equals a fixed multiple of a base amount. The base amount is one of three things, and the offer terms must say which one applies:
- Deposit only. The player must wager a multiple of what they deposited. The bonus itself is not counted in the base.
- Bonus only. The player must wager a multiple of the bonus amount they received. The deposit is not counted.
- Deposit plus bonus. The player must wager a multiple of the two amounts added together.
The difference between these three bases is not cosmetic. A requirement stated as a multiple of deposit plus bonus is, for the same multiple, a significantly larger total wagering obligation than one stated as a multiple of bonus alone. The reader who sees only the multiple and not the base has not read the offer.
The second number that matters is what counts toward the requirement. Not every bet contributes equally. Across operators, slots commonly contribute the full value of each bet toward the playthrough, while table games, live dealer games, and video poker contribute a reduced share or nothing at all. Some games are excluded entirely. The bonus terms on Castrump's page state which games count and at what rate, and that list is the single most important item on the page. A player who completes the wagering on a game that contributes nothing has completed nothing.
Where the offer can fail before it begins
Every bonus page contains conditions that operate before the player ever places a qualifying bet. These are the items that decide whether the offer can be completed at all, and they are usually stated in a block of small text below the headline offer.
Eligibility. A bonus may be available only to new accounts, only to accounts from certain regions, only on a first deposit, or only when a bonus code is entered. The reader who claims an offer without checking eligibility has not claimed an offer; they have made a deposit under terms they did not read.
Minimum deposit. A deposit below the stated minimum does not trigger the bonus. The deposit is still a deposit, and the player's money is still in the account, but the bonus simply does not exist for that transaction.
Time limits. The wagering requirement is not open-ended. A bonus that is not completed within the stated window is removed, along with any winnings derived from it. The clock usually starts when the bonus is credited, not when the player first logs in after claiming it.
Maximum bet during wagering. Most bonus terms cap the size of a single bet while a bonus is active. A bet above that cap can void the bonus and any winnings from it, even if the player was not aware of the cap. This is one of the most common ways a bonus is lost after it has been claimed.
What the page does not state, and what that absence means
A bonus page is complete only when it answers every question a player needs to work out whether the offer can be completed. When an item is missing, the absence is itself information.
If the page does not state the wagering multiple, the player cannot compute the total bet volume required, and the offer cannot be evaluated. If the page does not state which games contribute to the requirement, the player cannot know whether the games they intend to play count at all. If the page does not state a maximum bet during wagering, the player cannot know whether a normal-sized bet will void the bonus. If the page does not state a time limit, the player cannot know whether the offer expires before it is completed.
Each of these absences is a reason to read the general terms and conditions, where bonus terms are often repeated or expanded. When the bonus page and the general terms conflict, the general terms usually govern, and the conflict itself is a warning that the offer is more restrictive than the headline suggests.
Free spins and cashback: the two offers most often misread
Free spins look like the simplest offer on the page, and they are the one most often misread. The reader sees a number of spins and assumes the winnings from those spins are cash. They are not. Winnings from free spins are almost always credited as bonus funds, which means they carry their own wagering requirement before they can be withdrawn. The spins themselves have no cash value; what has value is the balance they produce, and that balance is locked until the playthrough is met.
Cashback is misread in the opposite direction. The reader sees a percentage of losses returned and assumes it is money back. It is usually a bonus balance, not a withdrawal, and it carries a wagering requirement of its own. Cashback is also calculated on a specific measure of loss — net loss over a period, loss on a specific game, or loss after winnings are deducted — and that measure is stated in the cashback terms. A player who does not know which measure applies cannot know what the cashback is worth.
Working out whether an offer can be completed at all
The reader's decision is not whether the bonus looks generous. It is whether the wagering requirement can be met before the time limit expires, under the game contribution rates, without exceeding the maximum bet, and with a balance that remains above zero. That is a calculation the player must do for themselves, using the numbers printed on Castrump's bonus page.
The calculation is straightforward. Take the base amount the terms specify — deposit, bonus, or both — and multiply it by the wagering multiple. That is the total bet volume required. Divide that volume by the contribution rate of the game the player intends to play. That is the actual volume of bets that must be placed. Compare that volume to the time limit and the player's own pace of play. If the required volume cannot be reached within the time limit, the offer cannot be completed, and the expected outcome is the loss of the bonus and any winnings from it.
The calculation does not require the player to know whether the offer is "good." It requires only that the player know what the offer is. Every number needed for the calculation is on the page. If any number is missing, the calculation cannot be done, and the offer should be treated as unreadable until the missing item is found in the general terms.
FAQ
Does Castrump's bonus page state the wagering requirement for every offer?
The bonus page states the wagering requirement for each offer in that offer's own terms block. When an offer's terms block does not state a wagering multiple, the general terms and conditions are the next place to look, and the absence from the bonus page itself is a signal that the offer is less transparent than it appears.
Do free spins winnings need to be wagered?
Yes. Winnings from free spins are credited as bonus funds, not as withdrawable cash, and they carry a wagering requirement of their own. The requirement is stated in the free spins terms on the bonus page, and the games on which the spins may be used are usually fixed.
What happens if a player places a bet above the maximum during wagering?
The bonus and any winnings derived from it can be voided. The maximum bet during wagering is stated in the bonus terms, and it applies to every bet placed while the bonus is active, not only to bets placed on the games that contribute to the requirement.
Can a player withdraw the deposit before completing the wagering requirement?
Withdrawing the deposit before the wagering requirement is met typically forfeits the bonus and any winnings from it. The terms on Castrump's bonus page state whether a withdrawal during the wagering period is permitted at all, and what the consequence is if it occurs.
