The time limit is the least of your worries, however, compared to this little complication: all the other boxes on the board move with your box. If you move your box one tile north, for example, then all the other boxes will shift one tile north as well. So you must plan your moves carefully so that you don't get your box or other boxes "trapped". You can also design your own levels using a built-in editor.

Collex Plus! is unique, fun, and very challenging at higher difficulty levels. Formerly released as shareware, the game has now been released into the public domain by its designer.
