Sudoku with pictures instead of numbers
Every puzzle here can be played with tiles rather than digits. Sprouts and toadstools, pancakes and coffee, moons and comets, or plain numerals if that is what you grew up with. The logic is identical: nine of each, one per row, column and box. Only the symbols change.
That makes it a gentler way in for anyone who finds a grid of numbers hard going, and a calmer one for everybody else. Each of the seventeen tile sets has colours chosen for its subject, from leafy Garden greens to Tidepool blues and bright Gemstones. The silhouettes stay distinct, so colour is never the only way to tell two tiles apart.
A room and song for each collection
Every tile set has its own illustrated room and soft instrumental score. The rooms and music began with generative tools. Each was then edited and matched to the board for this game. For new players, music starts quietly when you choose a puzzle. You can turn it off or change its volume in Sound settings.
Six difficulties that mean something
Difficulty here is measured by the hardest technique a puzzle genuinely requires, not by how many tiles start on the board. A grid with fewer clues is often the easier one, so counting them tells you very little. Cozy needs nothing but spotting the last free square. Gentle asks you to scan. Steady wants locked pairs and pointing lines. Tricky brings hidden pairs and triples, Devious needs wings and fish, and Expert needs the deeper versions of them.
Every puzzle is checked before you ever see it: exactly one solution, and solvable by reasoning alone. You will never have to guess, and there is never a second valid answer.
Free, and quietly so
No ads, no account, no newsletter. Puzzles are generated and solved on your own device. The game works offline once loaded and you can add it to a home screen like an app. There is a fresh daily puzzle every morning, the same one for everybody.
How your progress is kept
Your puzzle, your settings and your times are stored in this browser. There is no account and no sync, so clearing site data clears your progress and it will not follow you to another device.
Page visits and gameplay events are counted with a self-hosted copy of Umami, which doesn't use cookies. Events include puzzle difficulty, hints and mistakes, with solve times grouped into time buckets. This tells us whether people play and where they get stuck. Umami doesn't receive your board, pencil marks or solution.
Recorded games
Games played on this website are recorded and sent to the Crest Arcade server. Crest Arcade is the collection of browser games this one belongs to.
A record holds which puzzle you played and its difficulty, your Tidy notes setting, every move you made (tiles, notes, erasing, hints, undo, redo and reset) and when you made it, timed from the start of the game, the version of the game, the date, and how the game ended: solved, left for another puzzle, or closed part way.
We use records to replay and test games, to improve this one, and to build automated players that test our games.
A record doesn't identify you. It has no name, account, cookie or device ID, and the server doesn't keep your IP address with it. Records don't identify anyone, so we may keep them indefinitely. If your browser sends Global Privacy Control, nothing is recorded.
We may also share, license or sell records to other companies, including companies that research, build, train or test AI systems. A record shows how a person really plays, which is what automated players get compared against. A shared record holds only what this section lists. We don't try to find out who played a record, and anyone we share records with must agree not to try either. This covers games played from October 30, 2026. Games recorded before then are only used to replay, test and improve our games.
