BoxUp puzzles

This is a puzzle similar to 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.

These puzzles are all quite small and experimental, and no doubt much more could be done with larger grids. Some puzzles are rather maze-like, where-as others are more like sliding block puzzles. Watch this page for new puzzles in the future, I welcome contributions and feedback.
