Deterministic browser simulator

Test roulette systems against repeatable spins.

0xRoulette is a free, no-real-money simulator. Use a European single-zero wheel, inspect each bet’s probability and expected value, automate common systems, or run Lua strategies against a fixed seed so another person can reproduce the same sequence.

Three views of the same engine

Game mode provides the wheel and betting layout. Advanced mode adds automated systems and live risk metrics. Engineer mode adds a Monaco editor, sandboxed Lua runtime, backtests, and forward tests.

What a simulation can prove

A repeatable run can expose drawdowns, table-limit failures, and probability of ruin. It cannot turn a negative-expectation betting progression into an edge. See the fixed-seed evidence in the research studies.
