You must settle on the casino table with an amount (your income) you can not change during a game. the casino contains numbers, in our case they go from 0 to 99. Each time, you have to bet an amount of your income on a number (between 0 and 99). the numbers of the same parity are said to be of the same color, so there are two colors. you can win two ways and lose one way. If the number drawn is identical to the one you bet on, you win three times your bet that will be added to your income, if the number drawn is the same parity (same color) as the one you bet on, you will get the half of your bet which will also add to your income but otherwise you lose your bet, the amount will be deducted from your income. Even if you have not understood, try to play, you will see that it is easy to understand."); }
