Crystal Collector!

You will be given a random number at the start of the game.

There are four crystals below. By clicking on a crystal you will add a specific amount of points to your total score.

You win the game by matching your total score to the random number and you lose if your score goes above it.

The value of each crystal is hidden from you until you click on it.

Each time when the game starts, the game will change the value of each crystal.
