Rules of the Game

You will be given a random number at the start of each game. By clicking on one of the four crystals below, you will add a specific amount of points to your total score. You will win the game by matching your total score to the random number. You lose the game if your total score goes above the random number. The value of each crystal is hidden from you until you click on it. Each time the game starts, the values of the crystals change.
