Each turn is divided in three different phases: Trade, Display and Draw cards. Each player at his turn can make a trade offer and each player in turn responds in kind. Using the cards through trading and drawing players work to acquire five identical race cards in order to build a Space Station (which increases the number of cards you can draw each turn) or five identical technology cards in order to build a City (which gives Victory Points).
A variant play has been created in this game where each player, owns a planet divided in four different missions. If a mission is accomplished, more Victory Points are added to the sum and if a player completes all missions game ends.
