Every craps player has a favorite strategy — but few have seen what that strategy looks like over hundreds of sessions. Our Craps Strategy Simulator generates simplified session paths for common systems, letting you compare their volatility profiles, drawdown depth, and approximate bust risk side by side.
Important: this is a simplified session model, not a full craps state machine. It captures the general shape of each strategy’s risk profile — how smooth or volatile the ride is, how deep the drawdowns tend to go, and roughly how often you go broke — but it does not track individual come points, working odds, or exact roll-by-roll bet resolution. For precise payout math on specific bets, use our Craps Payout Calculator.

Monte CarloHow to Use the Simulator
This tool helps you visualize how different craps strategies behave over repeated sessions. Here is how to configure it:
- Select a Strategy:
- Pass + Odds: The classic low-edge approach. Smooth, low volatility.
- 3-Point Molly: Pass + Come bets with odds — wider coverage, higher variance.
- Iron Cross: Field + Place 5, 6, 8 — wins on every number except 7, but the 7 wipes out everything.
- Place 6 & 8: Simple, focused — only two numbers in action.
- Dark Side: Don’t Pass + Don’t Come — grinds out small wins but feels uncomfortable at a hot table.
- Set Bankroll & Bet Size: Your starting balance and base unit determine how many rounds you can survive variance.
- Run the Simulation: The simulator generates multiple session paths and shows:
- Session curves: Visual paths showing how your bankroll evolves over time.
- Bust Rate: Approximate percentage of sessions that end at $0.
- Average Drawdown: How deep below your peak the balance typically dips.

Understanding the Strategies
Why do different strategies feel so different at the table? Because they trade off between coverage (how many numbers produce a win) and exposure (how much you lose when the 7 rolls). Here is a simplified comparison:
| Strategy | Volatility | Winning Rolls | Biggest Risk |
|---|---|---|---|
| Pass + Odds | Low | Point numbers + 7/11 on come-out | Slow grind if points don’t hit |
| 3-Point Molly | Medium-High | Multiple points working | Seven-out wipes 3 bets at once |
| Iron Cross | High | Every number except 7 | One 7 erases many small wins |
| Place 6 & 8 | Low-Medium | Only 6 and 8 | Fewer winning rolls, slow action |
| Dark Side | Low | 7 after point established | Come-out 7/11 losses, social pressure |
What the Simulator Shows (and What It Doesn’t)
This tool is designed to give you a directional comparison — which strategies produce smoother results, which produce bigger swings, and which burn through bankroll faster. It captures the general shape of each system’s risk profile.
What it does not do is model the full complexity of a craps table: individual come points, working/not-working odds rules, press and regression decisions, or exact roll-by-roll bet resolution. For that level of precision, you would need a full state-machine simulator or physical-table tracking. This tool sits between “napkin math” and “full Monte Carlo engine” — useful for strategy comparison, not for exact bankroll requirements.
Frequently Asked Questions (FAQ)
Which craps strategy has the lowest house edge?
Pass Line with maximum free odds produces the lowest combined house edge — roughly 0.37% with 3-4-5x odds. Don’t Pass with lay odds is even lower at approximately 0.27%. The simulator shows this as smoother, more predictable session curves compared to systems like Iron Cross (which carries a blended edge of roughly 2–4% depending on bet mix).
Is this a true Monte Carlo simulation?
It is a simplified session model that generates random paths based on approximate payout rules for each strategy. It captures relative volatility and bust risk well, but does not track individual come points, working odds, or exact roll-by-roll resolution. Think of it as a directional comparison tool, not a precision engine.
Why does Iron Cross lose so much despite winning on most rolls?
Because the 7 — which appears on average once every 6 rolls — wipes out all active bets simultaneously: the field bet, and all three place bets. The many small wins ($1–$7 per roll) do not compensate for the periodic large losses ($22+ per seven-out). This asymmetry is why high-coverage strategies often have worse long-term results than simple pass-with-odds.
What bankroll do I need for a craps session?
A common guideline for recreational play: bring 30–50× your base unit for low-volatility strategies (Pass + Odds, Dark Side) and 50–80× for high-volatility strategies (Iron Cross, 3-Point Molly). The simulator helps you visualize whether your bankroll is large enough to survive typical drawdowns — but exact requirements depend on the specific odds multiple and table rules at your casino.
Is the Dark Side strategy better than Pass Line?
Mathematically, Don’t Pass (1.36% HE) has a slightly lower house edge than Pass Line (1.41%). With lay odds, the combined edge drops even further. But “better” depends on your tolerance for the social dynamics — betting against the table is unpopular, and the come-out roll is unfavorable for don’t bettors (7 and 11 both lose).
Can any craps strategy guarantee profit?
No. Every strategy on a standard craps table operates under a house edge. Systems like Martingale or Iron Cross may produce frequent small wins, but they do not change the expected mathematical loss. The simulator demonstrates this: even strategies with high win rates show negative drift over long sessions.
