Casinos are built on math. They know exactly how much they will win from you per hour based on the House Edge and Game Speed.
You should know this number too. This calculator estimates your Theoretical Loss for a session. Use this figure to set a rational “Stop-Loss” limit—the price you are willing to pay for the entertainment.
The Math of Losing
Different games burn money at different speeds.
1. Slots (The Money Burner)
Slots are fast (~600 spins/hour) with a high edge (4-8%).
- Betting $1 per spin = $600 wagered/hour.
- Expected Loss (@ 4% edge) = $24 per hour.
2. Blackjack (The Slow Grind)
Blackjack is slower (~60 hands/hour) with a low edge (0.5%).
- Betting $5 per hand = $300 wagered/hour.
- Expected Loss (@ 0.5% edge) = $1.50 per hour.
Conclusion: A $1 slot player loses money 16x faster than a $5 Blackjack player. Knowing this helps you choose games that fit your budget duration.
Frequently Asked Questions (FAQ)
Why did I lose more than the “Theoretical Loss”?
Theoretical Loss is an average over millions of spins. In a short session, Variance dominates. You could lose $100 in 10 minutes on slots even if the theoretical loss is only $24/hour. Always set your stop-loss higher than the theoretical average to account for bad luck.
