Hints that teach
A nudge first, then the technique by name, then the exact move. You decide how much help you want.

Classic sudoku along a hand-stitched journey. Every board you finish becomes a woven Tile to keep.
The first squares you fill come out pale and the last ones deep, so each Tile is a small picture of how you solved it. No two weave the same way.
1,000 levels wind from First Stitches to Loomoku Heights, and every chapter has its own felt cloth.

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.
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.
Not yet. Progress in the browser is saved in that browser only. The app keeps its own progress on your device.
Yes. Every level is a classic 9×9 sudoku with exactly one solution that can be reached by logic alone, with no guessing. From chapter 6 the Boss level of each chapter is an X-Sudoku, which adds the two long diagonals.
There are twelve grades in four tiers: Gentle, Steady, Tricky and Fiendish. Chapter one stays at grades 1 and 2, which need only the two simplest techniques. The last chapters reach grade 12, which calls for Swordfish, XYZ-Wing and simple coloring.
If the digit you tap is already visible in the same row, column or box, the move is refused and nothing is lost. If the digit is wrong in a way you could not see at a glance, it is marked and costs one life. Puzzles give you three to five lives depending on the grade, and in Gentle mode a wrong digit costs no life.
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.
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.
Yes. Every puzzle is generated on your device, so the app plays fully offline.
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.
