By clicking on one of the crystals above, you add points to your score. Your goal is to win the game by matching your score to the target number. But wait! Don't get too click-happy just yet. You lose the game if your total score goes above the random number.
The value of each crystal is hidden from you, but if you pay attention to how your score increments when you click on it, you’ll be able to discern its value. Each time you win or lose, the game will reset, and you will have a new target score to achieve. But don't get too excited—the value of the crystals will change as well.
