Picture Sudoku for Kids: Printable Sheets

Shapes instead of numbers, for children who are not counting yet. Every row, every column and every 2×2 box needs each of the four shapes once. Draw the shapes, or play on screen.

Every puzzle has exactly one answer, and you can always find the next shape without guessing. Tap an empty square to change its shape.

Sheet 1: Starter

Half the shapes are already drawn in.

How to play

  1. Draw a shape in every empty square.
  2. Each row has every shape once.
  3. Each column has every shape once.
  4. Each box, the squares inside the thick lines, has every shape once.

Tips for parents and teachers

  • Solve the first puzzle together and think out loud: "This row already has 1, 2 and 4, so this square must be 3."
  • Start with a row, column or box that has only one empty square left. That square is the easiest one on the board.
  • Use a pencil, so a mistake is easy to rub out.
  • Every puzzle here has exactly one answer and never needs guessing. If a child gets stuck, look for a number that fits in only one square.
  • Print the answer page on its own and keep it with the grown-up.
