In American roulette, the odds of hitting 0 or 00 are 2 out of 38 or approximately 5.26%. The payout for betting on 0 or 00 is 35 to 1, which means you’ll receive 35 times your original bet amount plus your original bet back. If you place a row bet on both 0 and 00, the odds of hitting either number are 4 out of 38 or approximately 10.53%. The payout for a row bet is 17 to 1, which means you’ll receive 17 times your original bet amount plus your original bet back if your bet hits.
It’s important to note that these odds and payouts apply to American roulette, while in European roulette, which is more common in India, there is only one green 0 on the wheel, so the odds and payouts for 0 would be different. When playing online roulette games for real money, you can find information on the specific odds and payouts by checking the game rules or by consulting the paytable.
