How it works

Only one straight-up bet can win on each spin. Its returned stake and payout must cover every other stake. More numbers increase hit frequency but also increase the total amount at risk.

Covering 12 numbers at 1 each costs 12. A 35:1 hit returns 36, for a net profit of 24.

Distinct numbers, equal stakes and uniform wheel pockets. Any wheel with 2–1,000 pockets is supported, including standard European and American wheels. La partage does not apply to straight-up bets.

net on hit = stake per number × (payout + 1 − covered); P(hit) = covered / pockets
