You will be given a Random Number at the start of the game, shown in the green box below.
Every time you click on one of the four crystals (below) a specific amount of points will be added to your total Crystal Points score.
To win the game match your Crystal Points score to Random Number. You lose the game if your Crystal Points score goes above Random Number.
Each time the game restarts a new Random Number will appear and the crystals will get new values!
