Puzzle Catalog
Browse the full library of puzzles and pick one to solve.
Every puzzle in this catalog is a hand-checked nonogram with a single, logically solvable answer — no guessing required. Browse by grid size to match the challenge to the time you have, or by theme to find a picture you'll enjoy revealing cell by cell.
Smaller grids like 5×5 and 10×10 make quick warm-ups that take only a few minutes, while 15×15 and 20×20 puzzles are proper sit-down challenges. Every puzzle is free, plays right in your browser with nothing to download, and needs no account.
What is in the catalog
Named puzzles, sorted into themes and spread across a dozen different grid shapes, from a five-cell-square sketch to a full 30×30. Every one has been checked for a single logical solution, and every one carries a difficulty rating that was measured rather than guessed — a solver runs each board and records how much chained deduction it actually takes.
Most of the catalog is rated normal, with a substantial minority at hard. Worth knowing before you browse: all thirty-five easy puzzles are the 5×5 letters and numbers, and nothing at 10×10 or larger is rated easy — so the jump from the easy shelf to the rest of the catalog is a real one rather than a gentle slope.
Two ways to browse, and why both exist
The same puzzle appears under a theme and under a size, because those answer different questions. Browsing by theme is for when you want to solve a particular kind of picture — the alchemy symbols, the zodiac, food and drink. Browsing by size is for when the constraint is time or skill rather than subject.
The size shelves are lopsided, and that is useful to know in advance. There are five of them — 5×5, 10×10, 15×15, 20×20 and 30×30 — and the catalog's centre of gravity is squarely at 15×15, which holds close to half of everything here. 10×10 is the thinnest shelf on the site and works better as a rung than a destination.
Where to start
If you have not solved a nonogram before, take the 5×5 letters. They are the only easy-rated puzzles here and they teach the notation without asking for technique. From there, 10×10 is where the overlap rule starts paying off properly, and 15×15 is where it stops being enough on its own.
If you already solve comfortably and want a theme rather than a size, everyday objects covers the widest range of grid dimensions in the catalog — eight distinct shapes — while animals is the gentlest of the larger sets, with only a handful of its boards rated hard. Zodiac signs and food & drink are the steepest — both have close to half or more of their boards at hard — so they reward being saved for later.
Frequently asked questions
How many puzzles are in the catalog?
Several hundred named puzzles sorted into themes, plus a separate pool of three hundred and twelve anonymous practice boards. The catalog grows in batches, so the exact figure moves; the folder list on the catalog page always shows the current count per theme.
What do the difficulty ratings mean?
They come from a solver that works each board the way a person would and records which techniques are needed. Easy means line-by-line logic is enough; hard means the board needs sustained cross-referencing between rows and columns.
Are the puzzles free?
Yes, all of them, with no account required. An account only keeps your progress and streak.
