Now testing on TestFlight

Sudoku Large brings a larger reading experience to classic Sudoku on iPhone. The app is in TestFlight testing as we refine the numbers, grid, and controls.

A closer look at the iPhone app

The beta centers on a familiar 9 × 9 puzzle with large, distinct digits. Clear box boundaries help you follow the board, and readable number controls keep the next move in view.

Explore the app to see how those details work together. You can also compare number sizes in the website preview.

For people already testing

Use TestFlight to find the available build and its release notes. Try Sudoku Large while holding your iPhone as you normally would, at your usual reading distance.

Feedback about the shape and size of digits, the visibility of grid lines, and the space around controls is especially useful. Send it through TestFlight or contact the team.

Looking ahead to the App Store

The App Store release date and final pricing have not been announced. This is a beta, so features and details can change as testing continues.

In the meantime, get to know the large-number experience, find your way to play, or learn a new technique in our Sudoku guides.
