15 Puzzle – Collect numbers

We are pleased to introduce the classic version of the 15 Puzzle game—"Collect Numbers"—faithfully recreated as it was originally designed in 1878 by Noah Chapman. To enhance your experience, we've added multiple difficulty levels and an automatic puzzle generator feature. The assembly function primarily serves to verify the solvability of a given number arrangement, ensuring you never encounter an unsolvable configuration. Rest assured, all possible combinations in our game are truly collectible and achievable.
