The players equip their planet, explore and use technologies, and produce goods. With their spaceships, they fly to the other players' planets in order to satisfy their demands by delivering required goods. While they are doing all these things, time is running as all players play simultaneously, and each player has only two sand timers to coordinate all actions. As soon as a sand timer, standing on a specific spot, has run out, the appropriate action takes effect.

Space Dealer is designed for 3-4 players. It is expandable up to 8 players with a second copy.
