Play the European version of Roulette
Most online casinos will offer both the American and European versions of roulette. The only excuse for not playing the standard European version is ignorance, because the American version produces a higher House Edge. European roulette does not offer the 00 on the wheel, thereby taking one more bet out of the equation, and lowering the House Edge to approximately 2.6% – the lowest edge at the table.
Place more even money bets than other wagers
The even money wagers will give the player the lowest House Edge at online roulette. These are the Red/Black, High/Low and Even/Odd bets, which have a 50/50 chance of winning. With these bets, a 1.3% House Edge is obtainable, and will help a bankroll hold out longer with more positive return. Additionally, it is only the even money bets that qualify for the "en prison" rule (see tip #3), which will bring the House Edge down even more.
Play a roulette table that offers the en prison or la partage rule
With this rule in place, which not all casinos offer, (and so therefore is a subject worth looking into when picking an online casino to play roulette at) the House Edge can be brought down to 1.35%. It states that when a 0 (and 00 for the American version) is landed by the roulette ball, all even money bets are not lost, but are rather afforded the opportunity to stay on the board for the next bet, or be taken back by the player. In the long run, this rule can be the deciding factor on whether a player ends in the red or not. It may not even come into play during a round of roulette. However, the fact that it can be exercised is quite reassuring, made evident by a House Edge reduced by half. Las partage, also called the Surrender rule, governs even money wagers in the same fashion, except that it returns half of the wager, thereby returning a 2.6% House Edge.
Do not place the five-number bet
The five-number bet, simply put, gives a House Edge of 7.3%. This is the highest casino advantage of any other roulette wager, and should always be avoided. With 5 to 1 payout odds, a player is better off taking the 8 to 1 payout on a corner bet.
As one can see, an approach to playing roulette can still be based on the numbers, as few as they might be. The Casino advantage and odds still change from bet to bet, but do so in such a way that making a wise wager choice is easy to not second-guess oneself over.
