What is Bonus Stacking?

Bonus stacking is holding or claiming more than one promotion at the same time, so that several sets of conditions apply to one balance. Most operators restrict it: a common rule is one active bonus per account, with any further offers held in a queue and released only when the current wagering is finished. Stacking matters because requirements do not merge neatly. Two bonuses can mean two separate turnover targets, two expiry dates and the stricter max bet rule applying to everything you play. Where terms forbid stacking, claiming a second offer while one is running can void both, along with related winnings. Before opting in to another promotion, check whether the queued offer starts immediately, whether it resets any expiry, and which bonus your next bet is drawn from.
