Crypto Roulette

Roulette is pure chance with a clear, fixed house edge — and the single most important choice you make is which wheel you sit at.

European vs American — always single-zero

European roulette has one green zero and a house edge of 2.7%. American roulette adds a double-zero (00), which nearly doubles the edge to 5.26%. There is no upside to the American wheel — always choose single-zero where it’s offered. Some casinos also offer French roulette with “La Partage,” which halves the edge on even-money bets to ~1.35%.

The bets and their odds

Inside bets pay more but hit less: a straight-up single number pays 35:1 (true odds 36:1 on a single-zero wheel — that gap is the house edge). Outside bets are lower-risk: red/black, odd/even and high/low each pay 1:1 and hit just under half the time (the zero is why it’s not exactly 50%). Columns and dozens pay 2:1. Crucially, every bet on the same wheel carries the same 2.7% edge — “safer” outside bets don’t improve your expected return, they just lower your variance.

Why betting systems fail

Systems like the Martingale (double your bet after every loss) feel logical but don’t beat the edge — they just trade many small wins for occasional catastrophic losses when a long losing streak meets the table limit or your bankroll. No progression, pattern or “hot number” changes a game where every spin is independent. Roulette is entertainment with a 2.7% cost, not a solvable puzzle.

Live and provably-fair roulette

Live-dealer roulette streams a real wheel in real time; the odds are identical to the digital game (single-zero live roulette is still 2.7%). Some crypto sites offer provably-fair digital roulette you can verify.
