Is it possible to win at roulette?
Of course, it is possible to win at roulette, as it is at any other casino game, in the short-term. However, even if you play the European, single-zero version of roulette – which offers a significantly lower house edge than the double-zero, or triple-zero, American versions – the game is designed to give the casino an inherent advantage, so you will always lose in the long-term. Furthermore, the longer you play roulette, the more likely it is that the percentage return for the casino, and hence the percentage loss for you, the player, will approach the house edge. Casinos lack clocks and windows and often ply players with free alcoholic drinks, so that they play, badly, for as long as possible.
Mathematically, it is impossible to win at roulette in the long-term, so the best a player can do is reduce the house edge to a minimum, focus on outside bets, which pay only even money, or 1/1, but offer a near 50% chance of winning and manage their bankroll. A European roulette wheel, with a single green zero pocket, offers a house edge of 2.6%, but an additional green double-zero pocket increases the house edge to 5.2% and an additional green triple-zero increases the house edge to 7.69%, or one of the highest that you are likely to find in the casino, outside of some ‘sucker’ bets on craps or keno. Granted that the payouts for all bets, inside or outside, are identical in single, double and triple-zero roulette, it becomes clear that players of either American version immediately place themselves at a disadvantage when compared with players of the European version.
