A virtual treasury of Sliding Block Puzzles

It's The Sliding Block Puzzle Page. You know: that puzzle with tiles numbering 1-15. The kind with the one empty square and the tiles that you slide around. Did you know that there are maybe hundreds of different puzzles that use a similar principle? And that many of them are actually online and waiting for your very own personal mouse?

The Sliding Block Puzzle Page is your personal portal to plethora of interactive sliding block puzzles - a plethora that is as inspiring in its artistic range as it is confounding in its elegant complexity.

Because the puzzles are untimed, there is nothing standing in the way of their becoming exercises in pure logic. Except perhaps your patience (some of the puzzles require more than 100 moves). Since you can take as long as you need, you can also get your friends and kids to help, which makes these puzzles valuable opportunities for collaboration and learning.
