The aim of the game is to correctly predict which of a continuous moving chain of carts a gold ball will land in when the play button is hit. The carts are randomly numbered 1-14 and randomly coloured either red or blue.

To start the game, you must first enter a stake using the '+' and '-' buttons at the bottom-left of the screen. When a unit stake has been selected, bets can be made by clicking on the bet options below the moving carts. Your 'Total' stake will be your original stake times the number of bets you have chosen (for example, putting 50 on odd, red and high will be a total stake of 150). This total stake will be deducted from your account balance.

When a stake has been entered and bets selected, the 'Play' button will turn green, indicating that you are ready to launch the gold ball. Clicking on the button will launch the ball around the screen and then drop it into one of the carts.

NOTE: To launch the ball, you MUST first have selected a stake and one or more bets.

When the ball has landed in a cart, your account will be credited if you have made any correct predictions and any losing stakes will not be returned. Your chosen bet(s) will remain selected in the betting region of the screen should you wish to bet again.
