There are 38 numbers contained on the online roulette layout - these include the numbers 1 through 36, plus the zero (0) and double zero (00). You can bet on any of these individual numbers, and if you play roulette, I bet you do. But outside of this scope, there are a number of bets the player can make as well. These are known, naturally, as the "outside" bets.

They're made on much larger groups of numbers; each one of them constitutes a wager on 12 numbers or more at a time.

Online Roulette - Odd or Even
This follows along the same principles as the Red or Black bet, in that when you place the bet, it will cover half the numbers that are not zero or double zero. Half the numbers are obviously odd, the other half are even. You will bet on whether the next number that comes up is an odd number or an even number.

So when you bet on an odd number to win, for example, on the next spin of the virtual "wheel" an odd number must land, in which case you will be paid at even money. If it doesn't come out to an odd number, or if the result is zero or double zero, you will lose the bet. The chances of winning this bet are 47.37% (you can do the math by taking the zero and double zero out of the equation).

The wager on the "Even" is placed in a box on the extreme left-hand side of the layout (that is, if you're looking at it length-wise), next to the "1st 12" box and one box over from the first dozen numbers (1 through 12) in the layout.

Your expectation number is as follows:

Expectation (E) = [(% chance of winning) X (amount won)] + [(%chance of losing) X (-amount lost)]

E = [(18/38) X (1)] + [(20/38) X (-1)] = 18/38 + (-20/38) = -2/38 = -1/19 = -.0526 = -5.26%
