About sudoku puzzles

Students fill a small grid so that every row, column and box holds each symbol exactly once. The 3×3 and 4×4 grids can use simple shapes (circle, square, triangle and plus sign) that children can draw, which makes them a first logic puzzle for kindergarten and first grade. Numbers on 4×4 and 6×6 grids suit older students.

Every puzzle has exactly one solution. Choose most squares given for a gentle start, or the fewest squares for a real challenge.
