Start with the wagering base
A 40x rule can apply to the bonus alone or to the deposit and bonus together. Those are materially different obligations. The reviewed Razed source, for example, applies 40x to the combined deposit and bonus balance.
Do not compare two offers until the wagering base, multiplier and expiry period are known.
Contribution changes the real workload
Slots may contribute at one rate while live games, table games or selected high-return titles contribute less or nothing. A game can also be excluded even when it appears in the normal lobby.
- Check the maximum bet while a bonus is active.
- Check whether bonus buys or jackpot games are excluded.
- Check whether a withdrawal cancels the remaining bonus.
- Check whether winnings or cashout are capped.
Eligibility is not universal
Country, account history, payment method, promo code and campaign dates can affect eligibility. A page seen by one account is not proof that the same offer is available to every reader.
