Two pennies are inserted and the first player to orbit their satellite around the earth wins a penny back. As the satellites progress, the planets revolve on their axes. This is one of the smallest two-player race games (most of which are robust, floor-standing machines). Characteristically, Mr Bryan protected it from overenthusiastic competitors, designing it to reward those who wind the handle at optimum, rather than maximum, speed. Wind too fast and the drive disengages.
Appropriately, this game arrived at the start of a much larger race which began with the launch of the Soviet Union's first satellite, Sputnik 1.
