Number 10 — the complete card

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

On the wheel

European rim, reading 8 · 23 → 10 → 5 · 24. American rim: 00 · 27 → 10 → 25 · 29. Racetrack membership: Tiers du Cylindre — 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: 10-11-12 (11:1). Split partners on the grid: 11, 7, 13 (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 10 — the honest numbers

At $10 per spin, 100 spins of straight 10 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 10: 1 in 1,369. In our 3.7-million-spin reference run, 10 landed 100,024 times against 100,000 expected (+0.02%) — textbook uniformity, the same verdict every number gets.
