Puzzle It is a sliding puzzle (also called 15-puzzle, Gem Puzzle, Boss Puzzle, Game of Fifteen or Mystic Square) that contains 4x4 tiles, that are mixed and make an image if they are placed in the right order. One tile (the "hole") - wich is located in a random corner - is empty. A (vertical or horizontal) nearby tile can slide (by tapping or swiping) into the empty space. The object of the puzzle is to place the tiles in the right order by making sliding moves that use the empty space.
