Instruction:
Drag a treasure to exchange it with one of the nearby gems to make a line of 3 or even more treasures of the same color. Make the suits of the same color with the monster to attack. Suit 3 or even more treasures of the very same color with the beast to assault it. Match sufficient treasures to pass and get rid of the beast through. If you do not do it fast sufficient, the monster will assault you! Yet concern not, there is a means to recover yourself.
