Daily Sudoku QR Mug - a New Puzzle Every Morning

A fresh Sudoku grid every morning, playable on the phone, opened by scanning the mug. Three difficulty levels, no app, no ads and no subscription.

How it works

1. Scan the QR code with the phone camera.
2. Pick a difficulty: easy (51 given numbers), medium (36) or hard (26).
3. Solve it on screen. Tomorrow the grid is a different one.

Why it is a mug and not an app

The daily puzzle already belongs to the morning routine, and so does the coffee. Putting the puzzle on the cup removes the step where you unlock the phone, find the app and get caught by three notifications on the way. The interface is deliberately plain: the grid, a keypad, nothing else.

Who it is for

The person who keeps a puzzle book on their desk, the parent whose five quiet minutes are the only five they get, and the newly retired, who suddenly have the mornings to spend on it. It is also a safe gift for a colleague you do not know well.

The mug itself

• 11 oz ceramic mug, dishwasher and microwave safe
• The QR code is fired into the glaze, so it survives the dishwasher and will not wear off
• Printed to order and shipped worldwide
• No app, no account, no subscription - any phone camera opens it

Common questions

Do I need an account to keep my progress? No account exists. The puzzle lives in the browser tab while you solve it.

Is the puzzle different each day? Yes, a new grid per day at each difficulty level.
