15 Puzzle – Collect numbers

Introducing the classic 15 Puzzle game – Collect Numbers – as it was originally created in 1878 by Noah Chapman. We’ve preserved its traditional gameplay while adding new features such as difficulty levels and an automatic puzzle generator. The assembly function is primarily designed to verify the solvability of a given number arrangement, ensuring that any combination you encounter is always achievable. Rest assured, there are no unsolvable configurations in our version of the game.
