15 Puzzle – Collect numbers

Introducing the classic 15 Puzzle game—"Collect Numbers"—faithfully recreated as it was originally designed in 1878 by Noah Chapman. We’ve enhanced this timeless game with adjustable difficulty levels and an auto-assemble feature. The assembly function primarily serves to verify whether a specific number arrangement is solvable, providing reassurance if you’re uncertain. Rest assured, all configurations in our version are guaranteed to be solvable; there are no uncollectible combinations.
