press the green flag, and the dice will begin to roll, when they stop, the number it the top left will change, you then click the buttons at the bottom, each of them will then change from purple to red (or visa versa), and subtract its number from the total roll amount(top left) after each round, you will be given a score, which is the total of red tiles flipped down number above the green button= rolls remaining
