When four sites in the same category all advertise 400% on the first deposit, the number has stopped carrying information. Everything that decides whether an offer is worth claiming sits in four rules underneath it, and those rules are rarely given equal prominence.
The wagering multiplier
This decides how much total stake has to pass through the account before anything becomes withdrawable. It is the largest variable in the category. The same match at 30x and at 50x are different products: the higher one needs roughly forty per cent more total stake to clear, which on a large bonus is a difference measured in sessions rather than spins.
The maximum stake while a bonus is live
A cap of around ten pence turns a large match into a long sequence of small spins. It is not a trap and it is not hidden, but it does make the offer unsuitable for anyone who plays at normal stakes. If you play small anyway it costs you nothing. If you do not, the offer is the wrong one regardless of its size.
Expiry and maximum cashout
A thirty-day window on a large multiplier sets a pace, and pace is what turns a bonus into a schedule. The cashout cap is the rule people find last: it sets the ceiling on what the whole exercise can pay out, no matter how well it goes.
- Read all four rules together before the percentage, not one at a time
- Check which games contribute to wagering and at what rate
- Check whether requesting a withdrawal forfeits the bonus balance
- Decide the deposit amount before reading the offer, not after
The option nobody advertises
Not claiming the bonus is a normal choice and it keeps the balance withdrawable. For a first account it is often the better one, because it lets you test verification and payout behaviour without a wagering requirement sitting on top of the result.
The wider point
A bonus is a reason to deposit more than planned, presented as a reason to deposit at all. If you are comparing sites mainly by bonus size, the comparison is already being made on the operator's terms.
