You don't have to outrun the monsters... if you can outrun your friends.
In this fast-moving game, you play your cards by matching numbers and suits. The first player to empty his hand wins... and the spooks get everybody else! Each suit (Spiders, Ghosts, Goblins, Skeletons, and Bats) has a special rule, and the top card in each suit has a special power... so you don't know who will be first to escape the haunted house until the final card is played. Spooks is a great quick party game... kids will enjoy it, too!
This is a light party game that despite its simplicity is still rather fun. Players are dealt cards and are trying to be the first go get rid of all their cards. Players must follow the rules of the suit last played: play another card of the same color, play another card of the same value, secretly bid in the same suit hoping to be the highest, etc. Each suit has a consequence if you cannot play, usually involved with gaining more cards.
