Now let us see what happens in the case of cross betting in European Roulette. A simple example of cross betting is wagering $10 on Red Numbers and $10 on Odd Numbers. There are 18 Red Numbers and 18 Odd Numbers, but a more detailed grouping is required. The first group contains numbers that are both Red and Odd, of which there are 8. The third group contains numbers that are Odd but not Red, of which there are 8. The fourth group contains numbers that are neither Red not Odd, of which there are 11. The last group includes the numbers “0”.
If a number from the first group is called the player will win both bets and win $20. If a number from the second or the third group is called then the player will win one bet and lose the other and end up quits. If a number from the fourth group is called then the player loses both bets and loses $20. In summary the player win $20 on 10 numbers; loses $20 on 11 numbers and ends up quits on 16 numbers. By suitable choice of cross betting the player can increase the percentage cover in which he is quits and wins and loses on few numbers only.
