Understanding Variance and Session Length
What is Variance?
Variance measures how much results deviate from the expected value. High variance games have bigger swings - you might win big or lose fast. Low variance games have steadier, more predictable results.
Game Variance Examples
- Low Variance: Frequent small wins, rare big wins (e.g., low volatility slots)
- Medium Variance: Balanced mix of wins and losses
- High Variance: Infrequent but large wins, long losing streaks possible
Survival Time Formula
Expected rounds = Bankroll / (Bet Size × House Edge)
However, variance means actual results will vary significantly from this expectation.
