The Roulette Odds
The game of roulette is a casino game that involves betting on the number that will come up when a special wheel is spun. Depending on whether you are playing American or European roulette, there may be either 37 or 38 different numbered slots on the wheel. In American roulette, the wheel is numbered 1-36, plus there are two zero spaces (0 and 00). In European roulette, the wheel is also numbered from 1-36, but there is only one zero space. That means there are 37 total spaces on the European roulette wheel and 38 total spaces on the American roulette wheel. So the odds of any one number coming up are 1:37 in European roulette and 1:38 in American roulette.
Bets are placed by laying chips on the game layout. This is an area of the roulette table that is marked with boxes for each number on the roulette wheel. Players can bet on any individual number, all of the numbers of one color (red or black), odds, evens, or combinations of numbers. Bets can be placed on the lowest half, highest half, first dozen, second dozen or third dozen. The types of bets available can vary from one casino to another.
How to Play
First, you’ll have a short period of time to place your bets. You do this by placing chips on the game table as described above. If you are playing online, you will place your chips by clicking your mouse in the area for the bet you want to place. Right click on the pile of chips if you want to remove or reduce your bet.
Once the time for placing bets has expired, the wheel will be spun and the ball is released. As the wheel slows, so does the ball. It will eventually drop into one of the numbered pockets on the wheel. If it lands in a pocket corresponding to the bet you have placed, then you win. You will receive a payout based on the odds for the bet that you placed. For example, on an even money bet (1:1 odds), if you bet $5 you will win $5. For a bet with 2:1 odds, you would win double the money you bet. Here are the odds for various roulette bets.
