What Are Buy Bonus Slots? The Complete Definition
Bonus buy slots (also called feature buy or bonus purchase slots) allow players to pay a fixed amount — typically 50 to 100 times their base bet — to skip directly to the bonus round. Instead of waiting for scatter symbols to trigger free spins naturally, you purchase immediate access to the game's most exciting feature.
💰 KEY FACT: Bonus buy was introduced by Big Time Gaming in 2017 with the release of Extra Chilli. Today, it's available in hundreds of slots across providers like Pragmatic Play, NetEnt, Hacksaw Gaming, and Relax Gaming.
Bonus buy slots offer several unique advantages:
- Instant Action: No waiting for natural trigger — get straight to the bonus
- Higher RTP: Bonus buy RTP is often the same or higher than base game RTP
- Controlled Variance: Know exactly how much you're spending per bonus attempt
- Time Efficiency: Skip 100-500 spins of base game grinding
- Perfect for Bonus Hunters: Players who only want to play bonus rounds

Pros and Cons of Bonus Buy Slots
Before using feature buy, understand the advantages and disadvantages:
✅ Pros of Bonus Buy
- Instant Action: No waiting 100-500 spins for bonus — get straight to the fun
- Time Efficiency: Spend your time playing bonuses instead of grinding base game
- Higher RTP: Bonus buy RTP is often higher than base game (some games 97%+)
- Controlled Cost: Know exactly how much each bonus attempt costs
- Perfect for Bonus Hunters: Ideal if you only enjoy bonus rounds
- No Scatter Droughts: Eliminates the frustration of long periods without bonus triggers
❌ Cons of Bonus Buy
- High Cost: 50-100x bet means you need a larger bankroll
- High Volatility: Results vary wildly — you can lose 10 buys in a row
- Not Available Everywhere: Some regulated markets restrict bonus buy
- No Base Game Wins: You miss potential base game wins and bonuses from natural triggers
- Risk of Quick Depletion: A few bad buys can wipe out your bankroll fast
⚠️ BONUS BUY WARNING
Bonus buy can deplete your bankroll quickly if you're unlucky. Never use money you can't afford to lose. Set a strict limit on how many bonus buys you'll do in a session. Only use bonus buy if you have at least 5-10 buy-in amounts in your bankroll.
Bonus Buy Strategy — How to Maximize Your Chances
Use these strategies to get the most from bonus buy slots:
- Bankroll Management: Have at least 10-20 bonus buy amounts in your bankroll. If each buy costs $100, you need $1,000-$2,000 to survive losing streaks.
- Focus on High RTP: Choose bonus buy games with 96.5%+ RTP like Dead or Alive 2 (96.8%) or Sweet Bonanza (96.5%).
- Know the Math: A 96% RTP bonus buy means you'll lose 4% on average over time. Accept this as the cost of entertainment.
- Set a Loss Limit: Decide before you start: "I'll do 5 bonus buys max this session." Stop regardless of results.
- Use Ante Bet for Lower Budget: If you have a smaller bankroll, use Ante Bet (25% higher bet) instead of full bonus buy to increase trigger frequency at lower cost.
- Study the Game: Watch streams or play demo mode to understand what features to expect in the bonus round.
💰 BANKROLL STRATEGY: For Dead or Alive 2 (60x buy), a $600 bankroll gives you 10 bonus buys. This is the minimum recommended. For Sweet Bonanza (100x buy), $1,000 gives you 10 buys. Never risk your entire bankroll on a single buy — the volatility is too high.
