Blonde Girl Strips A Red Dress At The Roulette Table

While not a strategy to win money, former Los Angeles Times editor Andrés Martinez described a betting method in his book on Las Vegas titled "24/7". He called it the "dopey experiment". The idea is to divide one's roulette session bankroll into 35 units. This unit is bet on a particular number for 35 consecutive spins. Thus, if the number hits in that time, the gambler wins back the original bankroll and can play subsequent spins with house money. However, there is only a = 60.68% probability of winning within 35 spins (assuming a double-zero wheel with 38 pockets).
• Labouchère System
The Labouchère System is a progression betting strategy like the Martingale but does not require the gambler to risk his stake as quickly with dramatic double-ups. The Labouchere System involves using a series of numbers in a line to determine the bet amount, following a win or a loss. Typically, the player adds the numbers at the front and end of the line to determine the size of the next bet. When he wins, he crosses out numbers and continues working on the smaller line. If he loses, then he adds his previous bet to the end of the line and continues to work on the longer line. This is a much more flexible progression betting system and there is much room for the player to design his initial line to his own playing preference.
This system is one that is designed so that when the player has won over a third of his bets (less than the expected 18/38), he will win. Whereas the Martingale will cause ruin in the event of a long sequence of successive losses, the Labouchère system will cause bet size to grow quickly even where a losing sequence is broken by wins. This occurs because as the player loses, the average bet size in the line increases.
