The players try to get 100 points by playing Straights. A Straight can be open (vulnerable to special cards but more valuable) or closed (immune to specials cards but only worth the half of an open Straight). Cards can be used to building Straight or for special actions (there is reminder text on the cards). There is a lot of interaction between the players because you have a lot of possibilities to mess with the other players and their Straights. Components 2-4 Players need 2 Sets of Cards (110 cards) and every player needs a die as action buffer. If you want to play with more than 4 players you need additional sets of cards.
