Roulette strategy & guides

At a first sight, playing roulette is extremely simple: you just have to guess what number the ball will end up after the wheel stops spinning. You bet against the house, so it should come as no surprise that the house has the edge (2.7% in European or single zero roulette, and 5.6 in American or double zero roulette).

Bets can be placed on numbered spots, lines, junctions or boxes. You can make a prediction regarding the exact number, the colour (red or black), whether the number is even or odd or if it’s high or low. You may also find games that use combinations of these types of bets.

If you place a bet on a line or an intersection of lines on the betting table, you increase the chances of winning but decrease the total win. You are free to move your bet even after the ball entered the wheel but you can’t do it anymore when the ball moves from the outer rim toward the numbered pockets.

In order to make the best possible bet, it helps to know the probability of winning for each bet. They vary slightly depending on whether you play European or American roulette. We will now give you the probabilities for the European variant.
