The player bets on two adjacent numbers on the roulette table. To do this, a chip is placed on the line between the numbers. For instance, in European roulette, you can bet 0 and 1 or 0 and 2. In American roulette, you can bet 00 and 0 or 00 and 2.
The potential payout is 17 to 1 ($17 payout for $1 bet on a split)
Among these zero-betting options, split bets have higher odds of winning since you can bet on multiple numbers together with zero. However, the straight-up bet system, which has lower odds, offers the highest payout for a zero bet.
Zero-betting won’t work in some bet options. For instance, outside bets usually exclude either 0 or 00 since this betting option focuses on “large” groups of numbers, such as even/odd numbers or red/black pockets. It’s also not possible to bet on zero using street wagers, as the zero pockets in both European and American roulette are not part of any row.
