In the roulette game, the player uses the joystick to place chips on the board. After all bets are placed, the game is launched by pressing the start button. Roulette wheel is stopped automatically after a timeout, or by pressing the stop button. If the player has won anything they are immediately put in the bonus game where the winnings can be gambled.
After a successful round in the roulette game, the winnings can be doubled (or lost) in the bonus game. In order to win, the player has to use the red and black buttons to “catch” the red and black cards that are alternating rapidly on the screen.
