Drag the sliders to see how many sessions your bankroll supports — and your live risk of running out.
Lower bankroll units and a higher house edge push this up. A simplified estimate — real sessions vary greatly due to variance.
Expected remaining bankroll after each session (average case). Actual paths swing above and below this line.
A healthy bankroll should have at least 200–500 betting units for slots (e.g., $500 bankroll with $1 bets = 500 units). This reduces short-term bust risk despite the house edge. For table games, 50–100 units is more typical.
These are theoretical averages. Variance means real sessions differ greatly from expected values.
