1. 4x4 Dot Sudoku: Count the Dots
Sudoku for children who can count but do not write numbers yet: four 4x4 puzzles where the squares show dice dots (one to four) instead of digits. The child draws the missing dot patterns so every row, column and 2x2 box has one, two, three and four dots. It practices subitizing, seeing a small amount at a glance, along with the sudoku rule. Ages 4 to 6, answer key in red dots on page 2. It is made for ages 4 to 6: pictures or dots instead of written numbers, and big squares for small hands. Start with the row, column or box that has the most numbers filled in.

Frequently asked questions
How many clues does a 4x4 sudoku need?
At least four. Our easiest puzzles give twelve or fourteen of the sixteen squares, and the hardest 4x4 puzzles on the warm-up page give six; every one still has a single solution.
How long does a 4x4 sudoku take?
A beginner usually needs two to five minutes for one puzzle; with practice it drops under a minute. A page of four picture puzzles is a good ten to fifteen minute activity for a preschooler.
What comes after 4x4 sudoku?
6x6 sudoku, with the numbers 1 to 6 and boxes of 2 rows by 3 columns. Start with the 6x6 picture sudoku or the easy 6x6 page, where many numbers are already filled in.
