Crystal Collector!

You will be given a random number of points to match at the start of the game. Each time you click on one of the four crystals below, a specific number of points is added to your total score. The value of each crystal is hidden from you until you click on it and the value of each crystal changes with each new game.

To win the game, you must match your total score to the random number. If your total score goes above the random number, you lose the game.
