Roulette doesnít have a strategy, since it is one of the easiest games to play and understand in the casino. Once you place your bet, you donít have to make any decisions. The easier a game is to understand the greater the house edge, and roulette is no exception. On all bets except the 5 number bet, the house edge is 5.26%. (The 5 number bet is worse.) The house take is much larger than it is at craps or blackjack.
