6×6 Sudoku for Kids
Ready for a bigger board? Fill every row, column and box with 1 to 6.
Once 4×4 feels easy, the 6×6 grid is the natural next step. The boxes are two rows tall and three columns wide, and you place the numbers 1 to 6. It rewards a little more planning while staying friendly and fun — a great bridge toward full-size sudoku.
