Understanding Slot Machine Odds
Slot machine odds determine your probability of winning and how much you can expect to win back over time. The key concepts include:
RTP (Return to Player)
The percentage of all wagered money a slot will pay back to players over time. For example, a 96% RTP means for every $100 wagered, $96 is returned as winnings (on average).
Volatility
How often and how much a slot pays out. Low volatility slots pay small wins frequently, while high volatility slots pay larger wins less often.
Low Volatility
Frequent small wins
Better for small bankrolls
Medium Volatility
Balance of small and big wins
Most common type
High Volatility
Rare but big wins
Requires large bankroll
