About This Game

Pixel Decode is a nonogram logic puzzle where the numbers along each row and column tell you exactly which squares to fill in. Work out the hidden runs cell by cell and a crisp piece of pixel art snaps into view: a heart, a house, a sailboat, a rocket and more. Every board is hand-authored from a real picture, so each puzzle has one clean, logical solution you can reason your way to without guessing. Play compact 5x5 grids for a quick mental warm-up or sink into meaty 15x15 challenges. Two marking tools keep your deductions tidy: Fill for cells you know are painted and Mark X for the ones you have ruled out. Clues cross themselves off the moment a line is satisfied, and the game confirms a win only when your grid matches the true picture. Free in your browser, no download, and built for both phone and desktop.

How to play

Read the clue numbers on the top and left edges: each number is a run of consecutive filled cells in that column or row, in order, with at least one gap between runs. On desktop, left-click a cell to fill it and right-click to mark an X on a cell you have ruled out; hold and drag to paint a straight line, and press F or X to switch the default click tool (handy on trackpads). On mobile, tap the Fill or Mark X toggle, then tap a cell; drag your finger to paint a line. Tips: start with the biggest clues, since a run of 4 in a width-5 row can only sit one or two ways and locks in overlapping cells. Use Mark X aggressively on cells that cannot be filled so you never lose track. Cross-reference a filled row against its columns to force the next deductions, and let the auto-crossed clues (they turn green when a line is complete) guide where to look next.
