An even money bet in roulette, or in betting in general, is when you have a 50 – 50 chance of winning and pays 1:1. In roulette this includes color bets even though the odds are just below 50 because of the green Zero. A 1:1 payout means that if you bet $10, and you will get $10 on top of your original $10 wager, giving you a total of $20.
