There are three main types of roulette: European, French, and American,
The biggest difference between them lies in the number of zeroes and the house edge
European and French roulette both feature a single green zero (0), which gives the house a relatively low advantage of 2.7%.
However, French roulette is the most player-friendly version because special rules like La Partage can cut the house edge down to a low 1.35% on even-money bets.
On the other hand, American roulette adds a double zero (00) to the wheel, bringing the total number of pockets to 38. making it mathematically the hardest version to win.
