Number 9 — the complete card

9 pays 35:1 straight-up ($10 wins $350 profit) on every wheel. It’s red, odd, low (1–18), dozen 1, column 3, and hits 1 in 37 European spins / 1 in 38 American. ⚙ computed

On the wheel

European rim, reading 14 · 31 → 9 → 22 · 18. American rim: 0 · 28 → 9 → 26 · 30. Racetrack membership: Orphelins — the announced bets that physically cover this pocket (math here). “Neighbour” talk means the rim, never the felt — two different maps.

On the felt

Street trio: 7-8-9 (11:1). Split partners on the grid: 8, 6, 12 (17:1 each) — an edge-of-grid number, fewer corners than the interior. Every combination prices identically: the 36-pocket fiction doesn’t care which squares you pick.

Betting 9 — the honest numbers

At $10 per spin, 100 spins of straight 9 wagers cost an expected $27 on European wheels and $53 on American — identical to any bet, wrapped in maximum volatility (SD 5.8). Back-to-back 9: 1 in 1,369. In our 3.7-million-spin reference run, 9 landed 100,031 times against 100,000 expected (+0.03%) — textbook uniformity, the same verdict every number gets.
