What it helps kids practice

Sudoku is really a game of noticing what is missing and figuring out what can go where.

  • Logical thinking.Using the numbers already in the grid to work out which one belongs in an empty square.
  • Visual scanning.Checking rows, columns and boxes carefully before choosing an answer.
  • Pattern recognition.Spotting what is already there and what is still missing.
  • Patience and checking.Sometimes the answer appears straight away. Sometimes one more look makes everything click.

Ready, set… think!

A printed page, a pencil and four little numbers are all you need.

  • Choose your paper size.Download the US Letter (8.5 × 11 in) or A4 version that fits your home printer.
  • Print at 100% or Actual Size.Choose Actual Size or 100% so the grids stay clear and the writing spaces keep their intended size.
  • Pencil works best.Sudoku is about testing possibilities, so a pencil makes changing one little number much easier.
  • Color is optional.The puzzles themselves work perfectly in black and white. Color is only used for the Kiddalou illustrations and to highlight missing numbers in the answer key.
  • Keep the answer key for later.All ten completed puzzles are collected at the back, with the filled-in answers shown in blue.

Small grid, big thinking

No sums. No counting tricks. Just four numbers and a little detective work.

A child does not need to be “good at math” to enjoy these puzzles.

The fun comes from looking at what is already there, ruling out what cannot fit and discovering the one number that can.
