Observation is a card game of speed and keen observation. Cats, dogs, monsters, robots, and other strange characters have invaded the police station and are running amok. It will take a sharp-eyed detective to sort this mess out! Roll the jumbo dice to determine "what" type of character to look for and "how many" characters you need to count - and when you observe them being played, be the first to slap the ringer to win the cards. Great family fun!
