What is Loomoku?

Loomoku is a calm sudoku game for iPhone and iPad with a hand-stitched felt-and-linen look. You solve classic 9×9 sudoku along a journey of 1,000 levels in 50 chapters, play one shared daily puzzle, and keep a woven Tile for every board you finish. It is made by Silvergrove Labs LLC.

Can I play Loomoku in my browser?

Yes. The first chapter, First Stitches, is playable at loomoku.com/play. That is 20 puzzles with notes, undo, hints and the Tile reveal. There is nothing to install and no account to create.

Does my browser progress carry over to the app?

Not yet. Progress in the browser is saved in that browser only. The app keeps its own progress on your device.

What is Gentle mode?

Gentle mode is an easier way to play. Journey puzzles are capped at grade 2 and Daily and Weekly puzzles at grade 3, all as standard sudoku. A wrong digit is marked but costs no life, and every hint is free. Stars still reward a clean solve. Turn it on or off in Settings; it applies from the next puzzle you start.

I ran out of lives. What now?

Choose Keep Going to get one life back and clear the wrong digit. It is free once a day and costs 40 Spools after that. Or choose Try Again to restart the puzzle at no cost. If lives are getting in the way, turn on Gentle mode in Settings.

How do hints work?

Hints come in three steps. A Nudge points at the area to look at and is free. The second step names the technique and explains it, and uses one Hint unless you are meeting that technique for the first time. The third shows the exact move and can place it for you. Hints come from the same solver that grades the puzzles, so each one is a real logical step.

I ran out of Hints. How do I get more?

If you have fewer than three Hints, you are topped up to three at the start of each day. You can also trade 20 Spools for a Hint in the Shop, and chapter rewards at 40 and 60 stars include Hints. In Gentle mode every hint is free.

Why did the game refuse my digit?

The digit you tapped is already visible in the same row, column or 3 by 3 box, so it cannot go there. Loomoku calls this a slip. It shakes the square, tells you where the clash is, and does not take a life.

How do I move my app progress to a new iPhone or iPad?

If you are signed in to iCloud, your progress follows you to your other devices on the same account; Settings shows whether sync is on. You can also open Settings, choose Export progress to save one backup file with your progress, settings and any unfinished puzzle, then choose Import progress on the other device. Importing keeps the best of both.

How do I reset my progress?

In the browser, open Settings from the Journey screen and choose Start over. In the app, deleting Loomoku removes the progress stored on that device. If iCloud is on for Loomoku, your progress may come back from iCloud when you install it again.

The music or sounds are too loud. Can I turn them off?

Yes. Open Settings from the Journey screen. Music and sound effects each have their own switch and volume, and haptics can be turned off too. On iPhone and iPad the Ring/Silent switch also mutes the game, and your own music keeps playing.

How do I turn on reminders, or turn them off?

Reminders are off until you switch them on in the app under Settings, Reminders. You can choose a Daily reminder at a time you pick, an Evening streak nudge, or both. Loomoku sends at most one a day and none once the daily puzzle is solved. Turn them off in the same place or in iOS Settings.

Does Loomoku work with VoiceOver and Reduce Motion?

Yes. Every square on the board is labelled for VoiceOver, helpful notices are announced, and decorative motion stands still when Reduce Motion is on. The browser version also supports screen readers, keyboard play and the reduced motion setting.

Are there ads, purchases or accounts?

No. Loomoku has no ads, nothing to buy with real money, and no account to create. Spools, the in-game currency, are earned only by playing.

Does the app work offline?

Yes. Every puzzle is generated on your device, so the app plays fully offline.

Which devices does Loomoku support?

iPhone and iPad running iOS 18 or iPadOS 18 or later, in portrait and landscape. The first chapter also runs in any modern web browser on a phone, tablet or computer.
