OkuDoku Number Brain Challenge is a unique combination of two classic games, Sudoku and Tetris. This game offers a challenging experience for puzzle lovers, incorporating the best elements from both games. Whether you prefer to compete against yourself by beating your own high score or take on the daily challenges, OkuDoku provides endless hours of entertainment.

The gameplay is simple yet strategic. Players must drag and drop blocks with numbers onto the board, aiming to build lines or squares that contain numbers from 1 to 4. Each time a line or square is completed with all the numbers, points are scored. As lines and squares are cleared, players can plan their moves to combine multiple lines and squares for even higher scores.

The game becomes increasingly challenging as players progress, requiring them to think a few steps ahead in order to complete the daily challenges and achieve high scores. With a new challenge released every day, players can test their skills and strive to reach the target score without running out of moves too quickly.
