Unfortunately, there is no foolproof way to beat the casino at the roulette table.
It is important to keep in mind that each roulette spin is completely random. The odds that the colour red will appear on the next roulette spin are 50% if it has appeared ten times consecutively (the actual odds on a European wheel is 48.6% due to the possibility of the ball landing in a 0, but they drop to 47.3% if you use an American wheel with a 00).
So, unlike card games where the previous cards dealt can affect the next card, every spin of the wheel is completely independent and has no relation to the past. Any mathematical system that relies upon historical data is unreliable, as the past has no relation to the next roulette spin.
You can increase your odds of winning at least some times. Remember to play roulette only for the fun of it and make sure you have the money to lose. I've never met a Casino owner who couldn't afford to lose.
If possible, you should always play on a European wheel of roulette, as the odds will be slightly in your favor. The house advantage for European roulette is 2.7% and for American, it's 5.26%.
Martingale is a popular way to beat the wheel. It dates back to centuries ago when gamblers bet on flipping a coin.
This system works by betting on something with an equal chance of winning - such as red or black or odd or even or high or low. You choose the same bet each time, and if it doesn't come up, you double your stake. If you choose to bet red, you will start with a PS5 stake. If the ball lands in black, you double your next stake, so that you again bet red but this time, you bet PS10. The next time you lose, your bet will be PS20. If your color comes up you get back all of your losses, and the equivalent amount of your original stake, in this case PS5.
You start over with your original stake after a winning.
It may seem foolproof, but there are two major flaws. You could lose your bankroll even before you make your choice. For example, if your losing streak is continuing, your 9th wager, if started at PS1, will need to be PS256. This would require a bankroll total of PS510. You would need to have a bankroll total of PS2,550 if you started with PS5. If you're losing, it is important to know when to stop. I recommend you only place a maximum of seven or eight bets casino siteleri.
Second, you will find that most online casinos have a maximum table bet. You can reach this limit before the game is over. If you start with a PS5 wager and the table limits is PS500, by the time the 8th bet was due, you'd be well over the limit (PS5, PS10 PS20 PS40 PS80 PS160 PS320 PS640).
There are still ways to increase your chances of making a profit.
Find a casino which offers a generous deposit to new players. This will help you build your bankroll.
The Martingale System is best used in the short-term. As you continue to play, you will be more likely to suffer a losing streak that can become costly. After a few wins you can change tables and your bets. Instead of betting on black or red, you should now bet on odd or even.
Play for no more than 2 hours. When you return, switch casinos to take advantage of the first deposit bonus. Check that you're playing at a European table and the table limits. Also, check the terms and conditions of the casino. Don't play more than you can afford! - enjoy!
