There's very little you can do to influence or predict the outcome of a ball spinning round a Roulette table. The important thing that you need to remember to make sure you've got a good strategy is that you base it on the outcome of each game and vary the amount of betting appropriately; more as you win, less as you lose.

Either you get lucky or you don't. Roulette moves more slowly than other Casino Games and for some reason players seem to try a load of different betting systems, especially on even-money bets. In the long run, none of them helps. No betting system can change the game's percentages, and some systems can be financial disasters for the player. Remember to opt for high-odds bets and don't plan to win every spin of the wheel. There are a few strategies that have been around for years, some players use them and some don't. We've listed the most popular ones below:

Martingale:
The player doubles his bet after each loss. When they win, they're left with a profit equal to their original bet. For example, a player bets £5 and loses, he then bets £10; if that loses, he bets £30, and so on. A win at the £20 level overcomes the £5 and £10 losses and the player has a £5 profit. The player then goes back to the original bet level. While this may sound like a good system, in reality you reach the large numbers very quickly, and run up against maximum bet limits. Runs of 7 or more losses happen on average once in every 121 sequences, and on that eighth bet, the house still has a 5.26% edge, as it does on every spin.

Grand Martingale:
This is a much faster and more strategic way to lose money. Instead of doubling the bet, after a loss the player doubles the bet and adds another original bet. So if the starting bet is £5, the next bet is £15 (£5 doubled, plus another £5), followed by £35 etc. The Grand Martingale player runs up against a £500 limit after only six losses, by which time he will have lost £600. Don't even bother.

Cancellation:
This is not as risky as the Martingales, but not great either. The player starts with a number or series of numbers and bets the total on either end. If he wins, he crosses off -- cancels -- the numbers just played. If he loses, he adds the total just played to the end of the series. When all numbers have been canceled, the result is a profit equal to the sum of the original numbers. A player bets £5 starts with the series 2-3 for the £5 starting point. If they win, they have a £5 profit but if they lose, the series becomes 2-3-5, and the next bet is £7. A win at £7 would cancel the 2 and the 5, leaving £3 as the next bet. A win at £3 completes the £5 profit.

If you adopt this strategy you won't have to bet large amounts of money, but can end up making bets considerably larger than the starting point and running up losses. Roulette looks like an easy game to try because it relies solely on chance. But the real skill comes in knowing how to bet before the wheel stops.
