▽What is Sudoku?

It's a pencil puzzle where you fill in the empty squares with numbers from 1 to 9, ensuring no numbers overlap vertically, horizontally, or in blocks.

There's only one rule. The rest is logic alone to reach the last square.

▽About Sudoku for Life

This app has been dedicated to Sudoku for 11 years since its release in 2015.

We've kept the screen simple, focusing solely on the board and numbers, without unnecessary visual effects. Yet, it includes all the necessary functions for playing.

No internet connection is required. You can play as usual, even in areas without reception.
