Strategy Simulator
Run any strategy across 50,000 rolls to see how the bankroll curve actually behaves. Change strategy and denomination, then re-run to compare variance across configurations.
Custom Bankroll Estimator
Playing a mix not covered above? Enter your total bets at risk and combined house edge to get a bankroll estimate. This is a quick math tool — if you want to actually build and play a custom strategy with progression systems, per-bet rules, and press patterns, use the full Strategy Builder on the main simulator.

Quick Reference: 2-Hour Session, $5 Denomination
Recommended bankroll for a 2-hour session at 90% survival. $5 denomination throughout (Iron Cross uses its $22 natural unit at $5 tables).
| Strategy | At Risk / Roll | House Edge | 2-Hr Bankroll ($5) | Expected Loss |
|---|---|---|---|---|
| Don't Pass + Lay Odds | ~$20 | 0.27% | $100 | ~$3 |
| Pass Line + 3-4-5x Odds | ~$22 | 0.37% | $150 | ~$5 |
| 5-Count | $5 | ~1.0% | $100 | ~$3 |
| Pass Line Only | $5 | 1.41% | $75 | ~$4 |
| Place 6 & 8 | $12 | 1.52% | $150 | ~$8 |
| 3-Point Molly | ~$30 | 0.80% | $300 | ~$10 |
| Paroli | $5–$40 | 1.41% | $200 | ~$8 |
| Fibonacci | $5–$55 | 1.41% | $300 | ~$8 |
| Iron Cross ($22 unit) | $22 | 3.90% | $500 | ~$37 |
| Hop the Sevens | $5 | 11.11% | $400 | ~$30 |
| Field Martingale | $5–$320+ | 2.78–5.56% | $800+ | ~$50+ |
| Pass Martingale | $5–$320+ | 1.41% | $600+ | ~$8 |
Martingale warning: Bankroll requirements scale with table maximums and losing streaks. A 6-loss streak (1-in-64 probability) requires a $320 bet on a $5 Martingale. The figures above assume a $500 table max cap. Bring significantly more or set a lower progression limit.
3 Rules That Actually Hold Up
1. Calculate on Total Exposure, Not Denomination
The number that matters is how much is on the felt when the dice roll. A $5 Pass Line player has $5 at risk. A $5 Iron Cross player has $22 at risk. Every bankroll calculation should start with total bets working, not the chip size. The most common mistake is treating the minimum denomination as the unit of risk.
2. Session Bankroll vs. Trip Bankroll
If you're in Vegas for three days and playing two sessions per day, don't split your total budget six ways. Each session should be independently funded — money you're willing to lose in full without affecting your next session's decision-making. Borrowing from tomorrow's session mid-session degrades every decision you make.
3. A Win Target Matters as Much as a Stop-Loss
Most bankroll advice focuses on stop-loss limits. Equally important is a win target. When you're up 50–100% of your buy-in, locking that profit and playing only the original amount limits downside without cutting the session short. The house edge doesn't care you're winning — it grinds every single roll.
