About this game

All 7410 puzzles are free. Sudoku, forever.

▽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.

Ratings and reviews

Love it. Although annoying having to un/reinstall the app to clear the prior solutions so I can do them again. Otherwise have to clear them individually and that takes too long.

It's a great collection of Sudoku variants. Minor bug: the program doesn't quit. And please, give me a paid version without the adverts.

This is exactly the app that I want to get!!

What’s new

Thank you for all your review feedback. This update fixes the display issues:
- Pencil-mark numbers are back to their previous size and darkness
- The selected cell's red frame is clearly visible again
- Grid lines are thicker and easier to see
- Fixed: eraser not working on pencil-mark-only cells
- Fixed: tap vibration staying on with sound effects off
- Fixed: music staying silent after ads
- The clock at the top is back
Sorry for the inconvenience - we'll keep improving.
