Historical Origins

The 15 Puzzle was invented by Noyes Palmer Chapman, a postman who introduced a similar game to his friends in 1874. The puzzle became popular in Hartford, Connecticut, where it was produced as Christmas gifts by students in 1879. Initially, the stones had to be placed by hand in any irregular order, adding to the challenge and fun of the game.

The Mathematics Behind the Puzzle

Our 15 Puzzle game is generated randomly, ensuring that no number is in its correct position at the start. To ensure solvability, a special parity algorithm is used. If a generated setup is unsolvable, the last two numbers are swapped to create a valid parity. This means you’ll always have a solvable puzzle to enjoy!
