Bonus-Buy / Feature-Buy

A bonus-buy (feature-buy) lets a player pay a fixed multiple of stake — commonly 50×–100× — to jump straight into the bonus round instead of waiting for a natural trigger. It compresses the game into its highest-variance part, usually at an RTP close to the base game, and it is restricted or unavailable in several regulated markets on harm grounds.

Instead of spinning for a scatter trigger, you pay a set price — commonly 50× to 100× stake, sometimes far more — to enter the feature immediately. Many games offer several buy tiers (a standard bonus versus a pricier 'super' bonus) at different prices and volatilities.

The buy price is set so the feature's expected return is close to the buy cost times a target RTP — often similar to the base-game RTP, sometimes marginally higher or lower. It does not remove the house edge; it compresses a large amount of variance into a single expensive decision, so bankrolls swing violently.

Feature-buy encourages larger, faster, loss-chasing spend and sidesteps the pacing of the base game. It is restricted or not offered in a number of regulated markets — it is not offered to Great Britain players, and it is prohibited under the rules in markets such as the Netherlands and Germany — while remaining common elsewhere.

A buy is a high-cost, high-variance bet on one feature outcome. The advertised feature RTP is a long-run average over many buys; a single buy most often returns less than it cost. It buys speed and size of risk, not better value.
