The "Buy Bonus" button typically costs 60× to 100× your stake. Press it and you skip straight to the free-spin round. Sometimes the RTP on the bought bonus is higher than the base game. Sometimes it's meaningfully lower. Here's how to check per slot and whether it's worth clicking.
What a bonus buy actually gives you
A bonus buy purchases a guaranteed trigger of the game's feature round — usually free spins or a scatter-based bonus. The cost varies:
- Sweet Bonanza: 100× base bet
- Gates of Olympus: 100× base bet
- Sugar Rush: 100× base bet (bought free spins with different multiplier grid)
- The Dog House Megaways: 100× base bet
- Fruit Party: 100× base bet
A $0.20 spin becomes a $20 bonus buy. That's the same stake as 100 base spins. So the question is: are those 100 spins worth more than the guaranteed bonus?
The RTP comparison
PragmatikPlay publishes separate RTPs for the base game and the bonus-buy path on the game info screen. On most slots the bonus-buy RTP is comparable to or marginally higher than base, in the range of a few basis points either way. The actual number for your session depends on which RTP configuration the operator has loaded (see the RTP guide for how PragmatikPlay ships multiple configs per slot).
Even when the buy RTP is a tick higher, variance dominates. A single bonus buy is one round; whether it beats the average is a coin flip.
The trap: bankroll blowups
The problem with bonus buys is not the RTP. It's the pace. On a $1 stake:
- 100 base-game spins ≈ 20 minutes of play, $100 wagered total.
- 1 bonus buy = 30 seconds, $100 wagered instantly.
Same wagering volume; wildly different session length. If you're prone to the "one more buy" loop after a low-paying result, bonus buys will turn a two-hour session into a fifteen-minute blowup.
Not every operator allows them
The UK Gambling Commission has taken a hard line on bonus buys as a responsible-play concern, and some operators extend that policy voluntarily to other markets. Availability comes down to the specific operator's policy. Curaçao-licensed sites (Rexbet included) offer the buy button on all supported slots; regulated markets (UK, several EU states, some US states) frequently disable it — always check the game info screen or the operator's terms.
The one-line takeaway
Bonus buys have a marginally better RTP but destroy session length. Use them sparingly to learn how a slot's feature pays, not as a session pattern.
