Pick a grid size and difficulty above, then hit Start new puzzle. You'll land on a fresh 6 × 6, 8 × 8, or 10 × 10 Patches Game board with its own shareable URL — send the link and the person on the other end gets the exact same board.
How Patches Game Unlimited Mode works
Every board is produced by a deterministic slicing-tree algorithm. We start with the full grid as one rectangle, then repeatedly pick a random region and split it along an axis until the board holds the right number of patches. The longer axis is usually split first so sub-regions stay interesting — but a random 30% of splits go the other way to keep Wide and Tall shapes in the mix.
Each split is seeded from your chosen size and difficulty plus a short random tail. That tail becomes the URL of your puzzle, so anyone you share the link with gets the exact same board — same clue placements, same solution.
Difficulty knobs
Grid size controls how many cells you're working with. 6 × 6 boards are the quickest, with 4 to 9 patches (Hard has the fewest and biggest). 8 × 8 nearly doubles the cell count, with 8 to 16 patches and longer deduction chains. 10 × 10 is the expert format, with 12 to 25 patches and the longest solve paths.
Difficulty controls what each clue reveals. Easy shows shape and size on every clue. Medium hides the number on about half of the clues, so you work out their size from the geometry. Hard turns most clues Freeform and drops many numbers — the grid becomes a logic puzzle more than a matching exercise.
Want to lock in a level? Jump straight to Easy Patches Game Unlimited Mode, Medium Patches Game Unlimited Mode, or Hard Patches Game Unlimited Mode — each one starts every board at that difficulty.
Every board is verified
A built-in solver checks each Unlimited Mode puzzle for a single solution reachable by pure deduction before it loads; a board that fails is discarded and the generator tries again. In the rare case no board with hidden clues passes after several tries, you get a fully numbered board instead, where every clue shows its shape and size.
