Sudoku is a classic logic puzzle played on a grid, and it only takes a minute to learn. Players use pure reasoning — no math required — to figure out exactly where each number belongs. That makes sudoku a fantastic brain workout for kids: it builds logical thinking, sharpens concentration, and strengthens number skills, one puzzle at a time.
How to play
Fill each row, column, and box with the numbers 1–6 without repeating any number. Look for rows, columns, or boxes that are almost complete, then use the process of elimination to work out which number fits each empty cell. Our book starts with easy 6×6 grids — the perfect size for beginners and young puzzlers.
