Sudoku 4×4 — easy

LabugenLabugen to color in

Sudoku builds logical thinking without any arithmetic: children just check what is missing from each row, column and box. The 4×4 picture grid suits 5-year-olds, 6×6 works from age 7, and classic 9×9 from age 9.

Choose the size, numbers or pictures, the level and how many puzzles per sheet, then download the PDF. The set number works like a key: the same number always gives the same sheet, and “New set” picks another one.

Every puzzle is checked by the program: it has exactly one solution, so a child cannot reach a different answer from the key. The answer key prints on a separate page, with the given numbers in black and the missing ones in red.
