What is the Bonus Buy Feature?
The Bonus Buy feature (also called Feature Buy, Bonus Purchase, or Ante Bet) lets players directly purchase access to a slot's Free Spins bonus round, bypassing the need to trigger it naturally through gameplay. Instead of waiting for 3 Scatter symbols to appear, you pay a fixed multiple of your base bet to instantly enter the bonus.
How Bonus Buy Works
- Standard price: Usually 50–100× your current bet (e.g. bet $1, pay $50–$100 for bonus).
- What you get: Immediate entry to the Free Spins or Bonus Game with the same RTP as naturally triggered.
- Different tiers: Some games offer multiple buy options (e.g. 6 FS for 50× bet, 12 FS for 100× bet).
Is the Bonus Buy Worth It?
Mathematically, the Bonus Buy has the same expected value as playing normally — it simply removes variance from the base game. The real benefit: you spend less time grinding and more time in the exciting bonus rounds. However:
- The premium can be steep (100× bet)
- You're taking on high bankroll risk in a single purchase
- Variance in the bonus itself is still high — you can land a 10× win on a 100× bet
