For a game like roulette, the online casinos will have a live dealer (or sometimes just a live wheel where the ball gets inserted automatically). All your bets are placed on your phone screen but the wheel spins in real life, and then the result is seamlessly digitized, so you're paid out immediately.

Live Roulette brings all the excitement and drama of a casino roulette table directly to your screen. Follow the action in real-time and chat with your croupier, or take part in our Slingshot Auto Roulette games for fast-paced, live-wheel action.

If you bet on 0 or 00 on an American wheel, and your bet hits, you'll get a payout of 35 to 1. If you place a "row" bet (betting on both 0 and 00), and your bet hits, you'll get a payout of 17 to 1.

The 0  (single zero) and the 00  (double zero) are the green slots on the roulette wheel. These pockets could receive a 35:1 payout if hit straight up. If there's a split, the payout could be 17:1. This type of bet is somewhat risky, but the payouts could be worth it.
