Sudoku with friends online

Enjoy a free number puzzle game of Japanese origin that combines offline challenges with online matches. Play with friends when you want to share the fun, or practise on your own without mobile data or Wi-Fi. Choose from difficulty levels ranging from easy to extreme and progress at your own pace. If you prefer a shared challenge, try the Sudoku two player mode and put your skills to the test against a friend. Choose a two player battle for a competitive session. The rules follow the classic Sudoku format: a 9×9 grid divided into 3×3 blocks. Fill the empty cells with numbers from 1 to 9, making sure that no number appears twice in the same row, column or block. Each puzzle invites you to use logic, examine the possibilities and find the correct solution one step at a time. Whether you enjoy a relaxing solo session or a Sudoku battle with friends, there is a challenge for different experience levels. Beginners can start with simple puzzles, while experienced players can choose more demanding options. Children aged 6 or 8 may also enjoy the easier levels, depending on their ability. As the puzzles become more complex, you can practise new strategies and build confidence. Start another battle in two player mode whenever you want a different challenge. For those who want to keep playing, infinite mode offers endless puzzles while preserving the traditional experience. Explore different difficulty levels, take your time with a tricky grid or enjoy a quick challenge during a break. This Sudoku game is free to play in 2026 and available in English. Its lightweight design takes up little space on your device, and the intuitive interface makes it easy to navigate and choose your next challenge. Solo play works without an internet connection, making it convenient at home, while travelling or wherever you want to spend a few minutes solving puzzles. Online matches require an internet connection. Enjoy a variety of Sudoku number puzzles, practise concentration and logical thinking, and switch between independent play and friendly competition. Choose your level, start a new grid and enjoy the challenge at your own pace. Invite a friend to a two player battle and enjoy another match.
