How to play Sudoku

Sudoku is a classic logic puzzle. Fill the 9x9 grid so that every row, every column and every 3x3 box contains the numbers 1 to 9 with no repeats. No math needed, just logic!

Why play Sudoku?

Daily Sudoku is a relaxing brain game that trains concentration, memory and logical thinking. It's perfect for a quick break, your commute or unwinding before bed.

About

A Hobby Project

Sudoku Expert started in 2019 during my computer science studies as a way to learn native app development with Swift for iOS and Kotlin for Android. Today I work as a software developer and keep improving the app in my free time. Since it is just a hobby, the app is free for everyone to use and may receive occasional updates. It is not built to track you, sell your data or make money.

Both apps are open source, so everyone can have a look at the code. Found a bug or have a suggestion? Open an issue on GitHub or just send me an email.
