Sudoku is a free Android game that allows you to play the well-known logic puzzle in English. The game features four levels of difficulty: easy, normal, difficult, and expert, so you can choose the level that suits your skills.

One of the great features of Sudoku is the ability to take notes, which helps you to keep track of possible numbers for each cell. Additionally, you can enable automatic verification to check for any mistakes and gray out numeric keys that have already been used nine times.

The game highlights the selected row, column, and block, making it easier to keep track of where you are in the game. It also highlights all fields that have the same value, which helps you to identify patterns and solve the puzzle more efficiently.

Sudoku offers automatic backup and loading of games, allowing you to continue where you left off at any time. The game is fully playable offline and optimized for both smartphones and tablets. The simple and intuitive design makes it easy to navigate and enjoy the game.
