Although American double-zero roulette has an extra number, it stills
pays the same as the European single-zero roulette. Of course this means that
the European version of the game is a better game.
Here is how the house edge works out:
| American Roulette |
| wager | winnings (w) | losses (l) | expected value(w - l) | *house edge(ev/aw * 100)
| | All 1:1 | 18/38 * 1 = .4737 | 20/38 = .5263 | -.0526 | 5.26%
| | All 2:1 | 12/38 * 2 = .6316 | 26/38 = .6842 | -.0526 | 5.26%
| | Split Streets 5:1 | 6/38 * 5 = .7895 | 32/38 = .8421 | -.0526 | 5.26%
| | Corner 8:1 | 4/38 * 8 = .8421 | 34/38 = .8947 | -.0526 | 5.26%
| | Street 11:1 | 3/38 * 11 = .8684 | 35/38 = .9210 | -.0526 | 5.26%
| | Split 17:1 | 2/38 * 17 = .8947 | 36/38 = .9473 | -.0526 | 5.26%
