Due to the house edge, the built-in statistical advantage of every game in the casino, the house does always win in the long run by taking in more money than it pays out. But individual players always stand a chance to win and quit while they are ahead. Some games like video poker and blackjack require skill to reduce the house edge to its lowest possible point. Other games, such as roulette and slots only require proper bankroll management and luck. Roulette offers players a chance to change or spread out their risk on every bet, but the green zero or zeros are always there. While the risk and reward ratio changes when you move from even money bets like odd/even, red/black to columns or even individual numbers, the odds stay the same except for one or two crazy bets like the five-number bet (0, 00, 1, 2 and 3) which increases the house edge from 5.26% to 7.89%. Playing on a single zero table will automatically reduce the house edge to 2.7% and a French roulette game with la partage or en prison lowers the house edge to 1.35% on even money bets.
