Description
The 15 puzzle (or tiles) is one of the most famous puzzles in the world. In the original version, it is a set of 15 square sliding tiles located in a square box. Using an empty cell for movement, you need to rearrange the tiles so that they stand in the order from 1 to 15 from top to bottom. The number fifteen gave the name to this puzzle.
