Lost Cities

Lost Cities is a card game in the Kosmos two-player series. The game consists of a single deck of cards of rank 2–10 in five different colors with three special "handshakes" ("HS" in scoring examples below) in each suit. A game board is included to organize discarded cards and help players organize their card collections.
The object of the game is to gain points by mounting profitable archaeological expeditions to the different sites represented by the colored suits of cards.
