Midnight is monster time, and the fun begins at 12 o'clock sharp when the cheeky guys come out of their hiding places. Time to catch them as quickly as you can! On your turn in Monster 12, you roll dice to try to match monsters on the face up monster cards. You can only roll the three dice that match the colour of the monsters you are trying to catch. If you reach the value of the respective monster, then you place the die on it, and whoever first catches twelve monsters of different colours wins.
