The buy feature is a paid option that instantly starts the bonus round. The cost is usually a multiple of the bet (e.g. 100x). Playing without buying keeps the same RTP, but waiting for scatters takes time.
When buying makes sense
- Exploring a specific game's bonus
- Testing a free-spin strategy
- Playing with a fixed bonus budget

All slots with the buy feature
Buying does not make a game "more winning": it only shortens the road to the bonus. RTP stays the same.
