What Is Sudoku?
Sudoku is a number logic puzzle played on a grid split into smaller boxes. Fill every row, column, and box with the same set of numbers so nothing repeats. There is no math or reading involved, just careful looking and logical thinking, which makes it a great puzzle for kids once the grid size matches their level.
Solving Sudoku builds number recognition, working memory, and patience. Kids learn to scan a row or column, spot what is missing, and check an answer against every group it belongs to, skills that carry straight over into math class and everyday problem solving.
Start with the 4x4 Easy grid for a first introduction, move up to the 6x6 Medium grid once that feels comfortable, then finish with the full 9x9 Hard grid for a genuine challenge.
