The 15 puzzle is a classic sliding puzzle game that has been around for over a century. It is a simple yet challenging game that requires players to move tiles around a board to form a specific pattern. The game is commonly played on a 4x4 board, with 15 tiles numbered from 1 to 15, and one empty space. The objective of the game is to arrange the tiles in numerical order, starting from the top left corner, with the empty space in the bottom right corner.


The gameplay of the 15 puzzle is straightforward. Players can move tiles around the board by sliding them into the empty space. The puzzle is considered solved when all the tiles are arranged in numerical order, with the empty space in the bottom right corner. However, the puzzle is not as simple as it may seem, and many players find it challenging to solve.

There are different strategies that players can use to solve the 15 puzzle. One common strategy is to move the tiles around the board in a specific order. For example, some players may start with the tile numbered 1 and move it to the top left corner of the board. They may then move the tile numbered 2 to the right of the tile numbered 1, and so on until all the tiles are arranged in numerical order.

Another strategy is to focus on moving the tiles around the board in groups. For example, players may focus on moving the tiles in the top row first, followed by the tiles in the second row, and so on until all the tiles are arranged in numerical order.

Difficulty Levels

The 15 puzzle comes in different difficulty levels, depending on the number of moves required to solve the puzzle. The easiest version of the puzzle requires only a few moves to solve, while the most challenging version requires over 80 moves to solve.

The difficulty level of the puzzle can be increased by shuffling the tiles around the board. Some players prefer to shuffle the tiles randomly, while others may use a specific shuffling algorithm to increase the challenge.


The 15 puzzle was invented in the late 19th century by Noyes Palmer Chapman, a postmaster from Canastota, New York. Chapman created the puzzle as a simple mathematical game to teach his students about permutations.

The puzzle gained popularity in the United States in the 1870s and 1880s and was eventually mass-produced by several toy companies. The puzzle was also popular in Europe, where it was known as the "Gem Puzzle" or the "Boss Puzzle."

In the early 20th century, the 15 puzzle became the subject of a controversy known as the "15 Puzzle Craze." The controversy centered around a claim by Sam Loyd, a famous puzzle designer, that he had created a version of the puzzle that was unsolvable. The claim was later proven to be false, but it helped to increase the popularity of the puzzle.

Today, the 15 puzzle remains a popular game, with many online versions available for players to enjoy. The game is also used in research studies to test cognitive abilities and problem-solving skills.
