Number 2 — the complete card

2 pays 35:1 straight-up ($10 wins $350 profit) on every wheel. It’s black, even, low (1–18), dozen 1, column 2, and hits 1 in 37 European spins / 1 in 38 American. ⚙ computed

On the wheel

European rim, reading 4 · 21 → 2 → 25 · 17. American rim: 35 · 14 → 2 → 0 · 28. Racetrack membership: Voisins du Zéro — 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: 1-2-3 (11:1). Split partners on the grid: 0, 1, 3, 5 (17:1 each). Every combination prices identically: the 36-pocket fiction doesn’t care which squares you pick.

Betting 2 — the honest numbers

At $10 per spin, 100 spins of straight 2 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 2: 1 in 1,369. In our 3.7-million-spin reference run, 2 landed 99,874 times against 100,000 expected (-0.13%) — textbook uniformity, the same verdict every number gets.
