Peter Box is a stylish, lightweight Soko-Ban clone with colourful Amiga-esque graphics and catchy music. The game plays by the classic rules, meaning that the objective of each level is to get all the boxes to specially marked tiles by means of pushing them. Since it is not possible to pull a box (e.g. out of a corner), the player must carefully plan each move. Puzzles in Peter Box are not timed, but the game will record detailed statistics of the player's performance, including time spent on a puzzle, the total number of moves and the number of pushes. These are summarised upon completing a puzzle. Levels are grouped into phases of increasing difficulty and different tilesets. Each level has an access password which is revealed upon successful completion of that puzzle. Peter Box was marketed as shareware, with the registered version containing 60 levels, and only a sample of levels from different phases available in the demo version.
