4×4 Sliding Puzzle – The Classic 15 Puzzle

The 4×4 sliding puzzle, also known as the 15 puzzle, is the most famous and widely played version of the game. It offers the perfect balance between simplicity and strategic depth.

Why 4×4 Is the Classic

• Enough tiles to require real planning
• Simple rules that hide deeper strategy
• Well-known patterns and solving methods

What Makes It Challenging

Unlike smaller grids, the 4×4 puzzle requires you to think several moves ahead. Solving one section incorrectly can undo progress elsewhere.

• Row-by-row solving becomes important
• The last row and column need special handling
• Efficiency matters if you track moves or time

Beginner Strategy

• Solve rows from top to bottom.
• Lock completed tiles in place.
• Learn the final two-tile cycle to finish cleanly.
