How to play
Left-click a square to fill it; right-click (or shift-click) to mark it empty. Numeric clues at the top of each column and the left of each row indicate the lengths of filled-square runs in order. Solve by logical deduction; no guessing should ever be required.

- Pixel-art image reveal on completion
- Auto-cross-out for verified empty squares

Editor review
Nonograms occupy the upper end of logic-puzzle complexity. Each puzzle has exactly one solution reachable through pure deduction, but the deduction chains required for the larger grids span dozens of steps and require careful note-keeping. Nonogram delivers a competent, well-designed implementation of the format.
The sixty hand-designed puzzles progress thoughtfully. The 5x5 grids are tutorial-scale; the 10x10 grids are accessible to anyone who has solved nonograms before; the 15x15 grids demand systematic technique; the 20x20 grids are genuinely difficult and reward multi-session attempts. The pixel-art image reveal on completion is the right reward — a small but satisfying capstone.
The mistake-detection toggle is the right concession for newcomers. Pure puzzlers can solve unaided; assisted solvers can use the flag without losing track of where they are. Recommended for logic-puzzle enthusiasts.
