BoxWorld is a puzzle game where the player has to place boxes over special places in order to gain energy to teleport to the next level. The boxes can only be pushed, not pulled, thus requiring ordering of the boxes with caution. If the boxes are put into positions that prevent further movement, the player can start the level over, but loses a life by doing so. There are no time limits, so the player can relax and think before acting. The game features nice graphics, enjoyable music, and 525 increasingly difficult levels. The player must come up with more complex strategies on the later levels, with many more pushes and special tricks in order to place the boxes in corners or long corridors. Sometimes most of the boxes are already placed in the appropriate area, but the player has to replace all the boxes just to be able to move another box and arrange it where it belongs.
