When you walk into a casino with $100, you aren’t just buying a chance to win; you are buying entertainment time. Casinos use a metric called “Time on Device” to ensure players stay engaged.
This calculator reverses that math. It tells you how many hours your bankroll should theoretically last based on your bet size and the game’s speed.
How to Estimate Your Session Length
- Bankroll ($): The total amount you are willing to lose in this session.
- Bet Size ($): Your wager per spin.
- RTP (%): The slot’s Return to Player (e.g., 96%).
- Speed (Spins/Hour):
- 600: Standard online play.
- 400: Relaxed land-based play.
- 800+: Turbo mode / Quick spin.
Example: The $100 Budget
You have $100 and bet $1.00 per spin on a 96% RTP slot.
- Cost per Spin: On average, you lose $0.04 per spin ($1 * 4% House Edge).
- Total Spins: $100 / $0.04 = 2,500 Spins.
- Time (at 600 spins/hr): 2,500 / 600 = 4.1 Hours.
Note: This is an average. High volatility slots can drain your money much faster, while lucky streaks can extend your time indefinitely.
Frequently Asked Questions (FAQ)
Why did my money run out faster than calculated?
This calculator uses the “Mathematical Average” (RTP). In the short term, Volatility dominates. If you play a high-variance game and don’t hit a bonus early, your actual “Time on Device” can be 50% shorter than the theoretical average.
