64 Roulette Strategy

A hit in either dozen resets both stakes to one; a miss in the unselected dozen or zerowheelZeroThe single green pocket that no even-money, dozen or column bet covers; the source of the house edge.

Progression table

Each row is a level before its outcome. The two same-sized dozen bets make the total stake twice the shown individual bet.

Worked example

Bet 1 on the first and second dozens. A 30 misses both bets, losing 2, and makes the next bets 3 and 3. If 18 then lands, the second dozen returns 9 including stake against 6 units placed: net +3 for that spin. Across the two-spin sequence, −2 + 3 = +1, then reset. The same recovery property is bought with rapid stake growth.

Cost and risk

Four consecutive misses cost 2 + 6 + 18 + 54 = 80 units. Six misses cost 728 units, and the seventh wager would require 729 on each dozen, 1,458 total.
