This game should generate 3 random colours, in the 3 coloured boxes to simulate the rolling of 3 dice. The player choose in the 3 drop down menu below the dice as guesses for what will be thrown.
When the button is is pressed, the 3 die are "rolled" and their scores are matched with the guesses in the boxes. The player is told if there are 0, 1, 2 or 3 matches.
