The Slide 15 Puzzle is also known as the Magic Square Game or the Puzzle of Fifteen. Regardless of the name, the fun remains the same! The puzzle is made of sixteen sliding, square pieces in a 4 x 4 square. Each square piece is numbered from 1 to 16. The first objective is to arrange the 16 squares in such a way that the sum of all horizontal, vertical, and diagonal lines will add up to the number 34. The second challenge is to place only 15 squares on the board, leaving square number 16 out of the mix.
