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

There will be four crystals located 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 assigned random number. However, you lose the game if your total score goes over the random number.

The value of each crystal is hidden to you, and you'll only be shown the value by clicking on it.

Please note that, each time the game starts, the value of the crystals will change.
