So given the numbers, what games should you consider playing to potentially get the biggest bang for your buck? The lowest casino win percentage among slot machine denominations and thus the highest win percentage for players is for nickel slots.
In roulette, the best odds are generally associated with the even money bets, such as red or black, odd or even, and high or low. These bets have the highest probability of winning, at nearly 50%, and offer a 1:1 payout.
