Crystal Collectors

You will be given a goal 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 goal. You lose the game if your total score goes above the goal.

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

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