15 Puzzle

The 15 Puzzle

The 15 Puzzle

Do you remember playing with this when you were a kid?

Do you still have one?

You can play this game online here. Unlike the physical puzzle, sometimes the online version is solvable, and sometimes it is not.  This is because the numbers have been randomly positioned and not mixed up by sliding them around.  To see whether the puzzle is solvable or not, click on the Parity button.  If the parity is odd, the puzzle is not solvable.  If the parity is even, the puzzle is solvable – go for it!
