A Sci-Fi equivalent of a car chase is that of a flight between asteroids, which is the premise that Asteroid Escape was designed. While there are only 8 sliding puzzle pieces in Asteroid Escape, the spaceship's progress is seriously limited because of its size and the size of some of the asteroids. One of the more complicated challenges requires more than 100 moves, so Asteroid Escape is not for the faint of heart.
The object of Asteroid Escape is to slide the puzzle pieces around until you can slide the spaceship off the game board. If you get stumped, the shortest solution is shown at the end of the challenge booklet.
