Casinos have different playing mechanisms depending on their players and their needs. Most casinos offer its roulette players either individual or group options. Players get a chance to bet either single numbers or group number varieties.
Ideally, a croupier or the roulette software helps in spinning the roulette wheel and ball in opposite directions over the wheel track. The ball then proceeds over the wheel in a descending momentum through the deflector area until it loses speed eventually. Naturally, the ball comes to a halt into one of the colored and numbered game pockets situated within the roulette wheel.
Now, players can decide to place a bet and risk their money to determine if the ball will land into their chosen pocket. The object of the game is to make sure the ball falls into the roulette wheel pocket players decided upon. This translates to a win.
However, in French style roulette, pocket number 0 means that the player has lost the game to the casino. Therefore, depending on the type of bet placed, winning is either on red or black, denoting odd or even numbers, respectively. Winners collect their winnings instantly, and if they lose, the house collects all the money.
