How to play Mini Sudoku

  1. Fill each empty cell with a digit from 1 through 4.
  2. Every row and column must contain all four digits without repeats.
  3. The same rule applies to each 2 × 2 box.
  4. Choose “Check puzzle.” Any valid completed solution is accepted.

A useful way to practice

Write down what is known and what is only assumed. Look for constraints that eliminate possibilities, then test a small next step. A wrong answer is useful information about the strategy you chose.

What your result means

This is a recreational logic activity. Results describe performance on this particular task, with this device and these rules. They are not a clinical assessment, IQ score or promise of improvements in daily life. Your best result and recent sessions stay in this browser; no account is required.

Is Mini Sudoku free?

Yes. You can play the full activity without a payment, download or account.

Can I use a keyboard?

Use Tab to focus buttons and Enter or Space to activate them. Answer fields accept normal typing. The maze also supports arrow keys. Timed tests will differ between touch, mouse and keyboard input.

Why did my result change?

Practice, a different generated puzzle, distractions and input timing all affect results. Compare several sessions rather than drawing a conclusion from one attempt.
