Latest1.3.0October 18, 2026

A place for every finished game

Fixes & polish: 1.3.1–1.3.1

Every finished Sudoku keeps its time, mistakes, and hints in My records. See your best and average times for each difficulty, or look back through recent games.
Earlier finished games on this device appear too. Your records stay here, ready to revisit without an account, even offline.

1.2.0October 17, 2026

A quieter new look, from the home page to your next Sudoku square.
Choose Paper & ink, Mist & pine, or Stone & amber. Light, dark, or your device’s setting — make yourself at home.
On your phone, the board takes centre stage. Find display settings, language, and rules in More.
Clearer notes, gentle highlights, and a little star on revealed squares. A digit takes a rest once all nine are on the board.
Install Calmtile for a window of its own and a quick way back. Supported browsers offer an install entry; Safari on iPhone and iPad has a short home-screen guide.
A new little C and a tile mark your spot — in your browser tab, on your home screen, and when you share Calmtile.

1.1.0October 17, 2026

You can keep Calmtile on your phone’s home screen and open it in its own window.
After your first visit, the board is there even without a connection. Start another puzzle whenever you like.
New versions wait for your next page visit or refresh. Your current puzzle can take its time.

1.0.0October 17, 2026

You can play a sudoku here. On a phone, the board, the tools, and the digits stay within reach.
Jot notes in a cell while you are still deciding. If a digit was only a hunch, undo walks it back out.
Pick a cell and you can reveal it. That counts as a hint. The other cells stay yours.
Pause the timer when you step away. You can hide it, too. Hiding only covers the digits; pause is what stops the clock.
When a pattern has a name, a short article is there, from a naked single through an X-Wing. Read one when you feel like it.
You can choose easy, medium, hard, or expert. Each one has twenty puzzles.
