The World-famous Fifteen Puzzle has stumped curious gamers since the 18th century. Invented by Noyes Chapman, the Fifteen Puzzle is comprised of 15 numbered puzzle pieces contained in a small 4x4 box that allows each of the numbers to slide around freely based on the fact that there is always an empty space somewhere on the puzzle board.
The goal of the Fifteen puzzle is to arrange the pieces so that the top row reads 1-2-3-4 (from left to right), the second row 5-6-7-8, the third row 9-10-11-12 and the bottom row 13-14-15 with the space in the lower right-hand corner. While the premise seems quite simple, actually solving the fifteen puzzle turns out to be quite confusing for most.
I have designed an AI robot in this game to help you whenever you feel difficult to solve an puzzle.
The AI robot simulates human way of thinking, so it is easy to learn, once learned, the strategy will allow you to not only solve the classic Fifteen puzzle, but also similar puzzles that have pictures instead of numbers on the faces of their puzzle pieces.
Enjoy it.
