Online Roulette is normally available in three main table game variants – European, French and American. The small difference in wheels used by European and American Roulette – one featuring a single zero and the other also a double zero slot, has a big impact on the theoretical return to player (RTP). Still, even though American Roulette comes with an RTP of 94.74% vs 97.30% of the European version, casinos catering to the US market also feature the first for the benefit of US fans.
As far as gameplay goes, both are played in the same way. The croupier spins the roulette wheel in one direction and the ball in the other, inviting players to guess the latter’s final resting place. There is a range of different bets grouped into two – Inside and Outside bets.
The first group comprises of Straight Up bet (an individual number), Split (two adjoining numbers), Street (3 numbers in a single line), Corner (4 numbers in a square layout), and Six Line (2 adjoining Street bets). If playing American Roulette, you’ll also be able to place Trio bets (a wager covering numbers 0, 1, 2 or 00, 2, 3) and Five number bets (wagering on 0, 00, 1, 2 and 3).
Red/Black, Even/Odd, High/Low (19-36/1-18), Dozen (1-12/13-24/25-36) and Column bets (12 numbers on any of the three lines) are all Outside bets. One major difference between Inside and Outside wagers is that the first is harder to win but offer higher payouts than the other.
French Roulette plays according to European rules with one important difference caused by La Partage rule, and in some cases also En Prison rule. In European Roulette, the ball landing on green zero slot will result in a loss of all chips placed on Even Money bets (Red/Black, Even/Odd, High/Low). Games featuring La Partage rule will instead give you half of your wager back, and those using En Prison rule will leave your chips on the same spot for the following spin.
