Keltis

Keltis is a board game designed by Reiner Knizia that won the Spiel des Jahres award for best game of the year in 2008. In the United States it has been marketed under the alternative title Lost Cities: The Board Game, with some rule variations, and it draws thematic inspiration from Knizia's earlier two player card game Lost Cities. Players advance tokens along stone paths by playing cards in ascending or descending sequence; playing too few cards of a color produces negative points, while four or more cards in a color yield positive scores, and one token doubles the points it collects.
