Touch: Tap a cell to cycle it through fill, cross, and clear · Keyboard: None — mouse/tap only (right-click to cross on desktop)
About:
An open-source Nonogram (Picross) game by bgonp, built with React and wouter. A single tap cycles a cell through filled, crossed-out, and empty — confirmed working correctly on touch, with clue numbers dimming once a row or column is solved. Desktop mirrors this with left-click to fill and right-click to cross. Four difficulty levels, a create-your-own-puzzle mode, and puzzle sharing. No analytics shipped. Note: the header grows a CREATE button and share icon once a puzzle is loaded that can overflow very narrow phone screens; the puzzle grid itself is unaffected.

Pixel PuzzleA clean nonogram/picross with three board sizes and a genuinely touch-friendly tap-to-fill, long-press-to-mark-empty control scheme.
