Roulette is primarily a game of luck, as the outcome of each spin is determined by random chance. The layout of the wheel and the distribution of numbers are designed to ensure randomness and make it difficult to predict where the ball will land.
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).
When you arrive to the table, locate the placard that shows minimum and maximum bets. You'll need to hand your chips to the dealer so they can give you a specific color this way, everyone can keep track of their own chips on the roulette table.
Atmospheric conditions continually change and the wheel itself has features that encourage randomness such as the size of the frets between the numbers and the diamond-shaped obstacles that intercept the ball as it falls down to the wheel. This means that you cannot predict the exact number where the ball will land.
