Do you love solving puzzles and want to keep your brain active? Sudoku is one of the best games for that. It is simple to understand but can get tricky as you play. You can now play Sudoku anytime on your phone — no need for a newspaper or pen.
In 2025, many Sudoku apps are available on Android and iPhone. But not every app is easy to use or fun to play. Some have too many ads, and others don’t work offline. So, this article lists the best Sudoku apps for 2025 that are easy, free, and worth downloading.
What Is Sudoku?
Sudoku is a logic-based number puzzle. It has a 9×9 grid, divided into smaller boxes of 3×3. The goal is to fill the empty boxes with numbers from 1 to 9, but each number must appear only once in every row, column, and 3×3 box.
Playing Sudoku helps your brain think faster, improves focus, and gives relaxation. Whether you are a beginner or an expert, Sudoku is a fun and smart way to spend time.
