Outcomes will land between roughly +$206.11 up and $-241.11 down. The expected-loss figure is the long-run average — any single session can swing well outside this range on high-volatility slots.
○ Methodology
How the math works
Expected loss = total wagered × (1 - RTP). Total wagered = bet × spins per hour × hours. Variance range shown at approximately ±2 standard deviations — actual outcomes swing wider than this in short sessions.
