Roulette wheel numbers and layout
The wheel order is different from the numbered betting grid. Use the single-zero diagram to identify pockets, colors and neighboring wheel positions.
Read the single-zero wheel
The supplied diagram follows the standard clockwise single-zero order beginning with 0, 32, 15, 19 and 4. Every label appears once. Eighteen pockets are red, eighteen are black and zero is green.
Wheel neighbors are not grid neighbors
Numbers next to each other around the wheel are not necessarily adjacent on the table layout. Inside split and corner bets follow the table positions. Named neighbor bets use a specified collection of component tickets.
37, 38 or 39 pockets
A European wheel has one zero. American double zero adds 00. Triple-zero games add a third zero or equivalent house symbol. The decorative photography on this site is not a layout reference; use the precise diagram.
Equal pockets in the mathematical model
The calculator assigns the same probability to each pocket and assumes independent spins. It does not analyze a physical wheel for bias and cannot predict the next result.
