When it comes to this type of roulette, you bet the amount of your choice (known as your starting bet) and then choose random numbers from three, five, seven and nine on the spin of the roulette online paypal wheel. When the numbers come out, you place your bet, then continue in the same manner. You can choose odd numbers, even numbers or any of the four numbers on the wheel, which correspond to the colors of the bet. When the ball lands on an odd number, you lose your bet and have to wait until it spins again.
