สรุป

Prisoner is a computerized version of the block-sliding puzzle game where the object is to move the blocks around so that the special piece (here, the "prisoner") can reach the opposite side (the exit). There is only one layout (the same layout typical for these puzzles) so this game won't have a lot of longevity. It's mainly interesting because it was created by the sysop of a BBS, The POWER Tower in England, as an advertisement.
