BoxUp puzzles

BoxUp is a variation on traditional Sokoban. In this warehouse however all the boxes are hollow and open on one side, in addition they can only be moved by pushing from the inside (rather than the outside). There are two sizes of boxes, small and large, the aim is always to push the small red box inside the large blue box. Black boxes may help or hinder your progress. Hint... a small box inside a large box can be pushed together.

June 2012: BoxUp is now available on iPhone, iPod Touch and iPad. Developed entirely in-house by clickmazes' very own Bill Mitchell, and with a brand-new puzzle set provided by Bob Henderson. From trainee and speedy, through quirky and sneaky, right up to nasty and beastly, there are plenty of puzzles to suit every skill level. And to celebrate the launch, a shiny new set of Bob's puzzles have been added below. Enjoy!
