In roulette, mathematically it is true that if you double up your stakes after a loss, you will eventually win all your money back. The trouble with applying that idea to anything in reality is that a losing streak can force some pretty large bets. You may not have the money to back it up but most certainly you will reach the house limit at some point in time. It is doomed to failure. Don't get caught by this because if you try it, it is likely to succeed for a time before the big crash hits you!
For the record, the simple doubling when you lose system is called the Martingale. You start with 1 unit on Red (or any Even Chance bet), then bet 2,4,8,16 and so on, as long as you lose. Whenever you win, you only make a profit of 1 unit. Conversely, the anti-Martingale system attempts to take advantage of those long runs by doubling up stakes as you win. This is done by placing your unit bet on an Even Chance choice and letting the winnings ride until you reach a number of consecutive wins that you thought of before you started. (1+1+2+4+8+16=32 or a return of 32 for 1 after five consecutive wins) This is as equally doomed as its older brother but it doesn't have the potential for catastrophic ruin in one outing.
The Labouch�re is an appealing try for betting on Even Chance bets. Take, for instance, six numbers 1,2,3,4,5,6 (you could have 4 or 8 numbers) and bet the total of the first and the last, 1+6=7. If you win you add that number to the end of the sequence, i.e. 1,2,3,4,5,6,7. Now play 1+7=8. If you lose you cross out the first and the last to leave you with 2,3,4,5 and then bet 2+5=7.
Three straight wins from the off and you'll win 24 units whilst losing 3 straight will lose 21 and cross out all the numbers. Of course you are likely to lose more often than you win but its a close thing.
This is a system that limits losses and plays up a 'good run'. Have a solid figure in mind at which you'll stop when ahead and when behind! This is fun and treated with care it will provide some chance to win and have good fun at the same time.
The d'Alembert is simply another adding and subtracting system for Even Chances. For example, bet 10 units on red and if you win, bet 9 on the next spin. If you lose bet 11. Whenever you get to a zero bet you are in profit. The big problem is that you could go on losing all night. It is not much liked.
There are three serious ways to win at the game of rulete. The third way is to cheat and we will not be condoning any method that involves cheating! We recommend cheats to head for the door.
The two serious attempts to win involve understanding the game and what it is all about. As a customer you may never have thought what is going on but will almost certainly have thought of betting systems that could win for you. Ask yourself why did you do that. Then sit down and begin thinking what the game is. It is a mechanical system for producing random numbers. Get it? No? Well the hint is, mechanical and random can never be in the same sentence.
Trust me good gamblers when I say that any way of beating a rulete game is so hard that the same effort spent in a normal business would make you a classic! Right then, what are they?
In the late nineteenth century, English engineer William Jaggers took 1.5 million francs from the Grand Casino in Monte Carlo. He had hired six clerks to record numbers from the roulette wheels for one month to find that they weren't true random number generators. He played the biased numbers for a long stretch and cashed big-time! If he could do it, so can others. This is very very tough, needing a lot of casino experience. Casinos nowadays take measures against this.
A wheel turning in one direction with a gentle slowdown and a ball travelling in the other with a fast but predictable decay. People have used computers to track both and predict where they'll meet. Lots of time and money to develop and if you get spotted they will bar you from entering the casino. This is as tough as it gets. In Nevada its illegal. Over here there is no law. However if they suspect you or can trump up a rumour about you, they will not pay you your money!
