About this game
A nonogram (picross) puzzle: the numbers beside each row and column tell you the runs of filled cells, and the only way through is logic. Fifty original pictures — lanterns, leaves, tools and small animals — in five themed packs from ten-second 5×5 warm-ups to full 15×15 pictures, each machine-verified to have a single solution.
How it works
Tap or click to fill, drag to paint a whole run, mark the cells you have ruled out, and undo any slip. Check highlights wrong fills up to three times; clean checks are free. An unlimited Reveal Cell hint helps when stuck. Assistance reduces the star rating. Each pack begins with line-logic puzzles; advanced puzzles are labelled.
Clue numbers dim as their runs are placed, the active row and column are enlarged for reading on a phone, and a 15×15 board keeps 20-pixel cells at 390 pixels wide without pinching. Progress, best times and half-finished boards are kept in local browser storage. Hand-written HTML5 with no dependencies and no network requests.
