The Future Of Casinos
Roulette by the Numbers
Roulette is a game of pure fortune, but its outcomes are governed by the laws of probability. Understanding the math behind the wheel can't change the odds, but it can help you make more informed decisions and appreciate the game on a deeper level. The key element is the "house edge," which is the casino's built-in advantage.
