In the game of roulette, a player can place aR$5 bet on the number 25 and have a 1/38 probability of winning. If the metal ball lands on 25, the player gets to keep theR$5 paid to play the game and the player is awarded in additionalR$175. Otherwise, the player is awarded nothing and the casino takes the playerR$5.
Say a single-number bet has a 35:1 payout, and you betR$1. If you win, you'll get your money back plusR$35. Another example: If you win aR$100 bet (for a 35:1 payout), you get a total of $3,600 ($3,500 profit plus theR$100 you initially bet).
The green zero pockets in roulette are the secret to how online casinos make money from the game. Once the ball lands in one, the house takes the winnings of that round. The green zero pockets are what most players fear the most as it nullifies all other wagers on the board. It is the element of risk on the wheel.
A player also may play colors, odd or even numbers, among others. A bet on a single number pays 35 to 1, including the 0 and 00. Bets on red or black, odd or even pay 1 for 1, or even money.
