Monsters on offer – you collect, exchange or score monster cards. If you reach 15 points with your monster groups you win. In each round the active player can auction cards and score points from 6 different monsters with values 2 to 7. The more valuable a monster is the more cards of this monster are there. Each player is dealt 8 cards. The active player can lay down monster groups = a number of cards equal to the value of the monster. One card of this group he takes for a scoring card, the other are discarded. Then he offers one card from pile plus one of his cards in hand. The other players bid for this with face-down cards. The active player accepts the highest bid and takes up the cards; the highest bidder gets the auctioned cards and is the next active player. The other bids remain on the table for the next round. To reach or top a score of 15 the active player can only lay out one group.
