A picross × minesweeper puzzle — solve the grid, uncover the picture.

Play it here

Every tile on the board is secretly either light or dark. Some tiles carry a number, and that number counts the light tiles in the 3×3 block around it — including itself. That single rule is the whole game: mark tiles light or dark, use each number to pin down its neighbours, and a hidden picture emerges from the grid as you go. Every puzzle is generated so it can be solved by pure logic — there is never anything to guess.

Picrossweeper comes in two forms:

• Single puzzle (play it) — one board at a time, 10×10 up to 25×25, hiding a small piece of pixel art. Pick a picture, pick a difficulty, take as long as you like.
• Giant grid (play it) — one continuous painting, up to ~54,000 tiles, cut into hundreds of irregularly-shaped regions and panned and zoomed like a map. Solve one region at a time; the artwork appears behind you as you go.

A visual tutorial walks through the rule, every clue from 0 to 9, and the two deductions that solve any board.

• Two ways to play — a small, self-contained single puzzle, or a giant region-by-region grid built from a full painting
• Load your own art — on the giant grid, drop in any image of your own and it becomes the puzzle
• Background music — a curated playlist of public-domain classical tracks, streamed from Wikimedia Commons, with play/pause, skip, and volume control
• Adjustable size — from a quick 10×10 to a giant ~54,000-tile canvas
• Four difficulty levels — Relaxed through Expert, trading off how many redundant clues survive pruning
• Hint and Check — reveal one logically-deducible tile, or highlight your current mistakes, without giving away the rest of the solution
• Playable on mobile — touch-friendly controls with a switchable tap mode for painting light or dark tiles with a single tap
• Multiple colour themes — shared across every page
• Progress saved automatically on the giant grid, so a painting can be solved region by region over multiple sessions

1. Every tile is either light or dark — nothing else.
2. Some tiles show a number. That number is the count of light tiles in the 3×3 block centered on it (the numbered tile counts itself).
3. A tile with no number is just part of the picture — it still needs to be marked light or dark, but it gives no direct clue of its own.
4. Fill in every tile so all the numbers agree with the tiles around them, and the hidden picture appears.

Controls: left-click (or tap) to mark a tile light, right-click (or switch tap mode) to mark it dark, click again to clear it. Drag to paint multiple tiles at once. Use Check to flag mistakes and Hint to reveal one tile you could have deduced yourself. On the giant grid, pan and zoom to move between regions — each region is solved independently.

There's no guessing required: every generated puzzle can be fully solved by logic alone, working outward from what each number rules in or out for its neighbours.
