Betting Only On Red

One conceivable strategy would be to bet on the ball landing in a red space for a certain number of spins, for example, 38.

There are 18 red spaces on a roulette table with 38 total spaces. Dividing 18 by 38 yields a probability of landing on red of 47.37%. This probability can be used in a binomial distribution and made into an approximate standard normal distribution.

Doing so indicates that, if one were to spin the wheel 38 times, there is a 99% probability that the ball would land on red at least 10 times. There is an 83% probability that in 38 spins, the ball will land on red at least 15 times. Out of 38 spins, there's a 50% chance that 18 will be red.

However, the break-even point is 19 spins, since the bet on red is 1:1, and the probability of 19 red spins in 38 is only 37%. This indicates the difficulty of winning by only betting on red.

The results occur because, as indicated by the 18 divided by 38 equals 47.37% figure, the ball will land on red less than half the time. This percentage applied in the binomial and standard normal distributions creates the vast divide in probability from 18 red spins to 19 red spins out of 38 spins. It is very unlikely for anyone to spin much more than 18 red spins out of 38 spins.

Betting Multiple Times

This type of bet is a combination of the red bet and the martingale system. The difference is that this bet also includes the odd. This strategy starts off with a bet of 1 on each the red and the odd (or you can do the black and even). Each bet is treated separately. When one bet loses, it is doubled. When one bet wins, it gets set back to 1. The reason that this technique keeps the player in the game so long is that there is almost a 25% chance of winning both the red and the odd and there is almost a 50% chance of breaking even (win one bet and lose the other). Of course, in order for this method to last, the player would need an unlimited source of money, and a casino with another one to boot. In reality, this method backfires when the player can't bet any longer and loses. The loss that this causes is possibly hundreds of times bigger than a loss made when starting. Also, in the long run, because the house still has an edge, the player will lose money just like with all other "unbeatable" casino games.

Labouchere System

The Labouchere System is 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 the outside 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.

Using The Dozen Bet

There are two versions to this system, single dozen bets and double dozen bets. In the single dozen bet version, the player uses a progressively incrementing stake list starting from the casino table minimum, to the table maximum. The aim here is to use a single dozen bet to win before the stake list ends. Many techniques are employed such as: betting on the same dozen to appear after two consecutive appearances, betting on the dozen that has appeared most in the last 15, 9, or 5 spins, betting on the dozen that, after a long absence of 7 or more spins, appears for the first time. The double dozen bet version uses two dozen bets and half the stake list size of the single dozen bet version.

1st And 3rd Column Strategy

One bet of 2 pieces on the 1st column and one bet of 2 pieces on the 3rd column covers most of the red numbers on the table. One bet of 2 pieces on the black will provide insurance for occurrence of black. This betting system covers nearly all numbers except for the 4 red numbers in the middle column and the zero (and double zero in American Roulette). If the result is a red number in either the 1st or 3rd column, the player only breaks even. If the result is red in the middle column the player loses 6 pieces. If the result is black and in the middle column, the player loses 2 pieces. If the result is a black in the 1st or 3rd column, the player only wins 4 pieces.

Mechanical Strategies

There are a number of roulette strategies which take a more mechanical approach to breaking the casino. The most famous is the biased wheel attack. In the biased wheel attack, the player clocks the wheel to find statistical deviations indicating some flaw to the wheel. Given that the wheel is man made it is quite impossible for the roulette wheel to be perfect. The biased wheel attack, seeks to find imperfect wheels and exploit the fact that some wheels will return numbers more often than 1 in 35, which means there is potential to have an edge over the casino. Clocking the wheel involves taking spin results in great numbers to identify any opportunities.
