RTP & Volatility
What these numbers mean and how to use them.
RTP and volatility are the two most important metrics for choosing which slots to play. Understanding them helps you select games that match your goals—whether that's longer play time or chasing big wins.
What Is RTP?
RTP stands for Return to Player—the theoretical percentage of wagered money that a slot returns to players over millions of spins.
For every $100 bet over the long term, you'll get back about $96. The $4 is the house edge.

What Is Volatility?
Volatility (also called variance) describes how a slot pays:
- Low Volatility – Frequent small wins, bankroll lasts longer
- High Volatility – Rare large wins, longer dry spells
Volatility Comparison
Volatility Characteristics
| Volatility | Win Frequency | Win Size | Best For |
|---|---|---|---|
| Low | Very often | Small | Entertainment, small bankrolls |
| Medium | Regularly | Moderate | Balanced gameplay |
| High | Rarely | Large | Jackpot chasers, large bankrolls |
| Very High | Very rarely | Massive | Big swings, loss tolerance |
Visual Example
Imagine betting $1 per spin for 100 spins ($100 total):
Low Volatility (96% RTP)
- Win 40-50 spins
- Wins average $2-3
- End with $85-$105 typically
- Rarely bust, rarely big win
High Volatility (96% RTP)
- Win 10-20 spins
- Most wins $5-15, rare $50+
- End with $0-$300 possible
- Often bust, sometimes big win
How to Choose

- Playing for entertainment with a small bankroll?
- → Low volatility, 96%+ RTP
- Want a shot at a big win and can accept losses?
- → High volatility, 95%+ RTP
