Sliding Piece Puzzle

The Sliding Piece Puzzle is quite popular, the rules are simple but it requires deep thought.

The object is to move the largest square out through the indicated slot (thick line outside the board).

There are about 50 problems, so you can kill 50 days.

Some problems have an answer page. Look at the bottom of each problem.
