Number 00 — the complete card

00 pays 35:1 straight-up ($10 wins $350 profit) on every wheel that carries it — American and triple-zero tables only. It’s green, sits outside every outside bet — defeating red/black, odd/even and high/low is its entire job, and hits 1 in 37 European spins. ⚙ computed

On the wheel

American rim: 13 · 1 → 00 → 27 · 10. Sector bets are a single-zero tradition — 00 belongs to none; its lone specialty is the 7.89% basket, best admired from afar. “Neighbour” talk means the rim, never the felt — two different maps.

On the felt

00 sits beside 0 atop the American grid: the 0-00 split pays 17:1, the 00-2 split exists on most layouts, and the five-number basket below is the only bet it anchors.

Betting 00 — the honest numbers

At $10 per spin, 100 spins of straight 00 wagers cost an expected $27 on European wheels — identical to any bet, wrapped in maximum volatility (SD 5.8). Back-to-back 00: 1 in 1,444. Its frequency claim needs no simulation: 1/38 on the only wheels that carry it, forever.
