From the manufacturer's web site: Players reach under the bed to find the matches on their score card. The monster gets nervous if a player is looking too long and will growl a warning sign. If a player has their hand under the bed for too long the monster pops out of the head board and that player has to clear off their score card. The first player to find and match three items in a row, wins! Includes 9Wx8Hx12L electronic monster bed, 12 gross objects, 4 score cards, 40 chips, and instructions. No reading required. Ages 4 and up
