Bonus Buy Slots RTP Data

Bonus buy (also called feature buy or feature purchase) lets you skip the base game and jump directly into a slot's bonus round for a fixed cost — typically 50x to 100x your stake. The mechanic is controversial: it accelerates the highest-volatility part of the game and concentrates spending into fewer, larger transactions.

The RTP implications are important. On most bonus-buy slots, the feature buy RTP is calculated within the game's overall published RTP. This means the feature buy is not a separate bet with its own return — it is part of the same mathematical model. If the operator deploys a lower RTP tier, the feature buy's expected return drops proportionally. A player buying features at a casino deploying the lowest tier is paying the same price for a bonus round that returns less on average. The games listed below all offer a bonus buy option. We flag which use variable RTP tiers and what the deployment spread looks like.
