Roulette outcomes depend on the wheel result and the rules of the specific table. This guide explains common payout terms and corrects the idea that a staking system can guarantee success. It does not verify the games currently offered by WABO.
Standard payouts are not double or triple for a single number
A standard straight-up wager on one number pays 35 to 1 in net winnings when it succeeds, with the original stake returned separately. Red/black and odd/even normally pay 1 to 1. A dozen or column normally pays 2 to 1. Special multiplier variants can use different paytables.
Why zero matters
A single-zero wheel has 37 pockets: 1–36 and 0. For a fair wheel, one selected number has probability 1/37 on a spin. With the standard 35-to-1 payout, the mathematical house edge is 1/37, approximately 2.70%. A conventional double-zero wheel has 38 pockets, producing an approximately 5.26% edge for most standard bets. These are long-run expectations, not a prediction of any session.
Read the exact table rules
Zero is not an ordinary red/black or odd/even result. Some tables offer special settlement rules for even-money wagers; these should never be assumed. Check the displayed paytable, zero rules, minimum and maximum stakes, and how interrupted or invalid spins are handled.
Staking systems do not change the wheel
Martingale and similar progressions change the amount exposed, not the probability of the next outcome. Losses can accumulate quickly, while finite funds and table limits prevent indefinite increases. No sequence of stakes guarantees recovery. Stop rather than increasing spending to chase a loss.
