This page is under construction.  For the moment, though, please visit Jared Weinberger's Puzzle Page for a variety of sliding block puzzles.

The above set of puzzles is by Reiner Muller, in his book Dominoes.
1.  Move the 0-0 domino (1-1 in second puzzle) to the upper right-hand corner.  To do so, slide dominoes into the free space.
2.  The pip numbers on the last domino moved may not border the same pip number on another square.
3.  At the end, the free space must be in the lower left-hand corner.

A simple peg jumping puzzle is available here.
