In roulette, numbers pay differently according to how the player wishes to bet. Even money bets are those on red/black, even/odd and 1-18/19-36. If you bet on these and win you’ll get the same amount back that you originally bet.
If you place bets that you’re less likely to win, you’ll get a higher payout if you do get lucky. You can win a big sum of money from just one bet in roulette, but it’s not easy to do so.
When you’re betting in roulette, there’s a quick and easy mathematical equation which can help you to remember what the payouts are. Divide 36 by how many numbers you’re betting on, then take away 1. This will give you your potential payout. You’ll also get your original bet back.
