Rules

The computer picks a random number at the start of the game between 19-120.

There are four crystals displayed, and each one is randomly assigned a value between 1 and 12, which varies for each game.

The player can click on any of the four crystals an unlimited number of times, to add points to the player's total score.

The player wins if their total score exactly matches the random number from the beginning of the game.

The player loses if their score goes above the random number.
