Beta: free for 30 days

The app works fully and for free for the first 30 days after you first open it. After that you can buy a one-time unlock code below. No subscription.

Every puzzle here has exactly one solution, checked with a solver before it reached the watch, not just pulled from a random generator. Move a cursor around the grid, pick a difficulty, and the app remembers your progress if you close it.

  • 300 puzzles, easy, medium and hard, all verified unique
  • Cursor over the grid, quick number picker for entry
  • Conflicts highlighted the moment a digit repeats
  • Optional pencil marks for candidates
  • Timer, auto-save and resume, completion check

How to use it

Open Sudoku Watch from the watch's app menu.

Controls: UP and DOWN move the cursor, START opens the number picker (1 to 9 or clear, MENU inside it adds a pencil mark), BACK opens the menu. Touch screens: tap a cell then pick a number.

Manual

Sudoku Watch: user manual

What it does

Sudoku Watch has 300 ready 9x9 puzzles in three levels: Easy, Medium and Hard, 100 each. The watch generates nothing; the puzzles come from a bank made on a computer. You get a timer, repeats highlighted at once, pencil notes, and your game is saved.

Installation

In the Connect IQ app on your phone (or Garmin Connect, then the Connect IQ Store) find "Sudoku Watch" by Dialforge, tap Install and sync the watch. Open it from the apps list: press START on the watch face, then pick Sudoku Watch.

First launch

With no saved game you first see the New puzzle menu: Easy, Medium, Hard. The puzzle is picked at random from that level. Given digits sit on grey squares, yours show in the accent colour. The 30-day free beta starts the first time you open it.

Controls

Watches with buttons (START, UP, DOWN, BACK)

  • UP and DOWN move the cursor square by square, row after row, wrapping at the ends.
  • START on an empty or your own square opens the digit picker. Given squares cannot be changed.
  • In the picker: UP and DOWN go through 1 to 9 and Clear, START confirms, BACK closes without a change.
  • MENU (hold UP) in the picker toggles a pencil note for the chosen digit. BACK on the board opens the menu.

Touch watches (tap, hold, swipe)

  • Tap a square to open the picker, tap a digit or Clear to enter it.
  • Hold a digit in the picker to toggle a pencil note.
  • Hold the board to open the menu. Swipes do nothing.

Settings

Phone: Connect IQ app, Sudoku Watch, Settings (the unlock code fields are there too).

On the watch, inside the app:

  • Resume: back to the puzzle.
  • Easy, Medium, Hard: a new random puzzle of that level replaces the current one.
  • Quit: saves and closes the app.

License

  • Free beta: 30 days from the first launch, everything works.
  • Price: 3.99 EUR once at dialforge.dev, no subscription. The 8-character code is tied to your watch's UID.
  • Where to enter it: phone, Connect IQ app, Sudoku Watch, Settings. Read the UID in "Watch UID (needed to buy a code)", buy the code, then type it into "Unlock code from dialforge.dev". The end-of-beta screen on the watch shows the UID too.
  • After the beta without a code: an end-of-beta screen with the UID replaces the app. Enter the code, then open it again. New watch? Write to us and the code moves for free.

Privacy and permissions

No special permissions.

No internet use. Data stays on the watch.

Troubleshooting

The code does not work. Check that the UID you bought for matches "Watch UID (needed to buy a code)" and type all 8 characters (case is ignored, no 0, O, 1 or I). A code for another app does not fit. Sync, then reopen.

How do I see my mistakes? A digit repeated in its row, column or 3x3 box turns its square red. The puzzle counts as solved only when the grid is full with no repeats.

How do pencil notes work? A noted digit is marked in the picker and shown small in the square. Entering a real digit there clears the notes.

Is my progress saved? Yes. The puzzle, your digits, notes and time are saved when you leave and restored on reopening.
