The Monsters are loose. Catch them again, but be aware of who you take on. And wich monster will join you in your fight at the end? Players have 2 piles with cards face up. On your turn you play one of these 2 top cards. You add your card to the row with the same color as your card. Jokers can be played as any color. When there are 4 cards in a row you have to take that row. Red and Blue rows score negative point, Yellow and Green rows score positive points. The trick is to not only look at your own cards but also what the other players will be able to play their next turn. Content: 104 playing cards, Rules.
