N-Puzzle

New Game ... 8-Puzzle (3x3) 15-Puzzle (4x4)

N-Puzzle instructions

Try to order the stones - from left to right and from top to bottom. The empty space must be bottom right.
E.g. the 8-Puzzle (3x3) is solved, when it looks like this:

1	2	3
4	5	6
7	8

• Reorder the puzzle by clicking on a stone next to the empty space. The clicked stone will shift to the
  empty space and leave an empty space, where it was.
• Try to use as few moves as possible to solve the puzzle.
• The puzzle exists in different (quadratic) sizes - e.g. 3x3 or 4x4. The number of stones names the puzzle.
  (The 3x3-Puzzle has 8 stones and one empty field and thus, is called 8-Puzzle.)
