This is a Swedish Monopoly-clone from the 1950's, judging by the look of it. Players take turns making "launch attempts" using the spinner, which determines their destination in the Sol planetary system. Unless a player has already bought the destination, it may then be purchased using "space fuel". When all planets/moons in a set are owned by a player, he or she may construct space stations which increases the amount of space fuel paid by other players landing at said station. There are also the equivalent of "chance" cards, which are written in sort of a pulpy SF style as befits the theme. Players are eliminated when they run out of fuel, thus eventually determining the winner.
