Number Swap Puzzle

Introduction to the tool and how to use it

The number puzzle asks you to put scrambled tiles back in order from 1 to N. Unlike sliding puzzles, you tap one tile to select it and tap another to swap them - they need not be adjacent and there is no empty space. Pick a size and shuffle intensity and press Start; moves and time measure your run, best records are kept per size, and the hint button shows where a tile belongs.
