Keep the lights on in the pit.
0xRoulette is free and has no accounts. The simulator and this support page run no display ads. If it taught you something, or just killed an interesting afternoon, the cheapest way to help is to buy a book you were going to read anyway.
The shelf
Not filler: 13 books that actually map to the problem this tool poses: is the house edge a wall, or a lock? Probability for the math, advantage play for the people who went looking, Kelly for the bankroll, and the simulation texts underneath every spin you backtest here. Some you'll finish in a weekend; some will outlast the project.
Every link is an Amazon affiliate link (tag 0xroulette-20) that goes straight to the book, no search pages. Buy through one and Amazon pays us a small commission at no extra cost to you. Full terms on the Disclosure page.

|---|---|---|
Fooled by Randomness The hidden role of chance in markets and life. Read it before you mistake a hot streak for an edge. | Amazon →no extra cost | |
The Drunkard's Walk How randomness rules more of the outcome than anyone wants to admit. The intuition pump for everything this tool measures. | Amazon →no extra cost | |
An Introduction to Probability Theory, Vol. 1 The canonical text. Rigorous, unforgiving, and the source of the math your simulator only approximates. | Amazon →no extra cost | |
Probability Theory: The Logic of Science Probability as extended logic, for reasoning about uncertainty, not just sampling from it. Deep end of the pool. | Amazon →no extra cost | |
| Beating the HousePeople who went looking for the edge. One of them found it.4 titles | ||
Beat the Dealer The book that proved a casino game could be beaten with math. The original pit-vs-house energy, from the man who did it first. | Amazon →no extra cost | |
A Man for All Markets Thorp's own story, including the wearable computer he and Claude Shannon built to beat roulette. Yes, that's a real chapter. | Amazon →no extra cost | |
The Eudaemonic Pie A band of physics grad students builds a shoe-computer to predict the wheel. The closest thing this audience has to a founding myth. | Amazon →no extra cost | |
Bringing Down the House MIT students, card counting, Vegas for millions. Pop, not proof, but it's the dream the math quietly serves. | Amazon →no extra cost | |

Other ways to help
- Tell a developer. The people who get this tool tend to know others who would.
- Send a strategy. Interesting Lua strategies and benchmark results may end up in the research log.
- Report what breaks. Error states are first-class here. Tell us when one isn't.
What's next on monetization (optional hosted backtests and an API tier for heavy users) is tracked openly on the research page. We'll never paywall the core simulator.
