Roulette RTP follows the wheel layout. One green zero (European) keeps the house edge at 1/37. A second zero (American) pushes the edge to 2/38. The payout table looks the same for many bets. The extra zero pocket changes the win probability.
Method: even-money expected value
Take a 1-unit even-money bet such as red. European wheels have 18 red, 18 black and 1 zero (37 pockets). Win probability is 18/37. Lose probability is 19/37. Expected value is (18/37)×1 + (19/37)×(−1) = −1/37 ≈ −2.70%. House edge is about 2.70%. Equivalent RTP is about 97.30%.
American wheels add 00 for 38 pockets. Even-money EV becomes −2/38 = −1/19 ≈ −5.26%. House edge is about 5.26% (RTP ≈ 94.74%). Straight-up single number bets use the same pocket counts with a 35:1 price, which yields the same edge on these two layouts.
See RTP vs house edge for the conversion formula used across games.

| American (double zero) | 5.26% | 94.74% | The extra 00 nearly doubles the edge for identical-looking bets. |

Live dealer vs RNG
Live roulette uses a physical wheel. RNG roulette uses software outcomes. Both can follow European or American layouts. Read the help screen for pocket count and any rule changes (for example la partage on even-money losses when zero hits). RTP Ledger does not certify a live wheel's maintenance.
