Install on a computer

  2. Choose the install icon in the address bar, or open the browser menu and choose Install Sudoku Pilot.
  3. Confirm the installation. Sudoku Pilot will open in its own window.

You can keep using the site in a normal browser tab if installation is unavailable. Offline access comes from the saved app files, while installation adds a convenient launcher and standalone window.

What works offline

The app saves its board, coach, and puzzle generator for offline use. Generated puzzles, manual entry, pencil notes, hints, and technique controls can run from those saved files.

Sudoku Pilot also stores the current grid, notes, undo history, difficulty, and enabled techniques in the browser. Each browser and device keeps its own copy.

Screenshot recognition is an optional online action that sends the selected image to Sudoku OCR through RapidAPI. It requires a connection and available provider quota. Manual puzzle entry remains available offline.

Test it before a trip

Open Sudoku Pilot with a reliable connection and wait for the page to finish loading. Start a puzzle, then switch the device to airplane mode. Close and reopen the installed app.

The board should return with your progress. Clear local data, clearing browser storage, or uninstalling the app can remove saved state and may require another connected visit.
