Feature purchase
A bonus buy charges a multiple of the base bet to trigger or attempt a feature directly. The entire purchase price is the wager denominator.
Published feature-buy RTP can differ from base-game RTP in either direction.
Ante or chance boost
Some games raise the per-spin wager in exchange for a greater feature probability. Compare added cost with the change in expected feature value.
A higher trigger rate may be funded by lower base-game awards.
Variance
A purchase compresses many units of exposure into one event. Even when RTP is similar, bankroll swings can be much larger than ordinary spins.
Maximum-win marketing should not substitute for distribution data.
Restrictions
Jurisdictions may prohibit bonus buys or require separate certifications. Online operators can impose bonus-fund maximum-bet rules that interact with purchases.
Confirm legality, eligibility, and promotional terms before use.
