Loved by players of every age and skill level, the goal of Sudoku - a fun, addictive logic game - is to fill all 81 spaces on the 9x9 playing area with numbers, such that all digits 1-9 are used once per row, per column and per 3x3 region. Designed with balance in mind, our innovative approach to Sudoku equally engages both halves of the brain - the right side works on numerical challenges and reasoning while the left side focuses on colour patterns and creativity. Although the large game board and colourful numbered pieces are designed to be enjoyed collaboratively with a partner, it's just as fun to play individually.
