Our sliding puzzle solver just got a lot more capable. Stuck on something bigger than a classic 15-puzzle? It now solves boards all the way up to 8x8, not just the usual 3x3-4x4 sizes.
Setting up the board is easier too: instead of typing numbers into each cell, you now drag tiles into place, which is way faster to get right. Picture puzzles got the same treatment — the photo-matching tool that reads your puzzle from a screenshot now works across all sizes from 3x3 to 8x8, with a smoother drag-and-drop editor for building the picture by hand.
If a puzzle genuinely can't be solved, the solver now tells you honestly instead of guessing, with a clearer hint on how to double-check your setup.
