Originally, roulette went by many different names like “little wheel”. The same is still true today. Yet, the basic premise hasn’t changed: That little ball needs to land on a number and color favorable to your bet, otherwise, the house takes it all.

There are three main forms of roulette: American, European, and French. They all require the use of a numbered wheel and a table where the bets are placed. The exact process used for betting depends on the casino and the croupier, but generally, you place your bets until the croupier waves their hand over the table, after which no further changes can be made and the fate of your chips is determined by where the ball lands.

The American and European versions use the same table for bets, but the wheels are slightly different. In the American version, there is a double zero slot in addition to zero, decreasing your odds of winning and doubling the house. So instead of 1 to 37 odds as in the European version, the odds are 1 to 38 while payouts generally remain the same. The French version of the game (and dare we say, the most authentic) uses a European style wheel but has a different table layout for betting. Whichever version you play, you need to remember that the house has an edge that could cost you dearly.

These same formats have carried over to online versions quite well. Fears of games being rigged appear to have been unfounded as online games prove to be as random as a non biased, real-life wheel thanks to the use of random number generators. Roulette really is a game of skill and winning or losing on one spin does not affect what will happen in the next. That said, there are some strategies to follow, especially when playing in an online casino.

You generally get a lot more bonuses in an online casino. At most, you get one simply for signing up and some others give you bonus money on every spin you make. This reduces the house advantage and with some careful placing of chips, you could walk away with a nice chunk of change.

Other strategies get more mathematical. The Martingale is often quoted in roulette strategy and requires the player to double their bet after every loss in the hope of an eventual win, which in theory would recover all the money from previous losses while winning a profit equal to the original stake. This works fine if you’re a millionaire who doesn’t have to worry about going bankrupt or are playing in a high-stakes environment without a betting limit.

The D’Alembert, on the other hand, is slightly safer but requires you to walk away when you’ve had as many wins as you’ve had losses, otherwise, the system doesn’t work. It requires you to increase your bet by one after a loss and decrease by one after a win. It’s a small profit, but a profit nonetheless.

If you’ve got a calculator handy, the Fibonacci strategy could make a losing streak work to your advantage. Start small and use the Fibonacci sequence to determine how much to bet. You move down the sequence with a win and up with a loss. It can get quite complicated, so you might want to have a visual aid somewhere to refer to.

The thing to remember, though, is that past outcomes have no effect on future ones, so even if red has come up the last six spins, that doesn’t mean that black is due a turn. Or that you’ve lost the last 10 rounds so you’re “due” a win. If systems like that worked, casinos worldwide would be bankrupt. The takeaway: You need to know when to walk away, especially from the online versions.
