Mini Sudoku Online — 6×6 Grid

Mini sudoku uses a 6×6 grid divided into six 2×3 boxes. The rules are identical to classic 9×9 sudoku but with numbers 1 through 6. Each row, column, and box must contain every number exactly once. The smaller grid means faster solves — typically 3 to 8 minutes — making mini sudoku perfect for a quick brain workout or for players who are new to sudoku and want to learn the logic before tackling the full 9×9 grid.
