Choose between 3 and 10 numbers from the 80 displayed on the main grid. If you wish you can choose how much you want to stake by dropping down the 'Stake' box to the right of the grid. Click on one of the Play buttons for the computer to choose its random selection of 20 numbers. Clicking the Play 1 button plays just one game whereas clicking the Play 5 or Play 10 buttons, plays that number of games automatically using the same numbers. The computer then chooses 20 random numbers and if you match a certain number then you win the points shown in the "Hits and Payout" box on the left. High winnings above 100 can be recorded at the end of a game in the High Score Table.
