Diamond Roulette is a roulette variant, which made its debut in Atlantic City in November, 2008. The game plays like conventional roulette, except the numbers 1 to 36 are colored red, blue, green, yellow, purple, and black, six numbers per color. A bet on an individual color pays 5 to 1, for a house edge of 5.26% in double-zero roulette, and 2.78% in single-zero.
In double-zero roulette, six bets are available on a combination of any one color and the two zeros. These bets pay 3 to 1, for a house edge of 15.79%. In double-zero roulette these bets pay on a combination of one color and the single zero. Under single-zero rules, these bets pay 4 to 1, for a house edge of 5.41%.
All the other bets normally found in roulette are also available, except the traditional even money red and black bets.
The version in Atlantic City is on a double-zero wheel. As with convention double-zero roulette in Atlantic City, even money bets only lose half if the balls lands in either zero.
