Evolution's American Roulette uses a double-zero wheel containing numbers one to thirty-six, zero and double zero. The extra pocket is its central rule difference from single-zero European roulette. The betting layout also includes the American Five Bet alongside standard inside and outside positions. This entry concerns the live-wheel edition, rather than Evolution's First Person simulation. A familiar colour or number wager still needs to be checked against the selected wheel: the additional double zero changes the outcome set even when the interface otherwise looks similar.

The library also explains roulette wheel formats and multiplier rules to help put these mechanics in context.
