Number sudoku: explained simply

Fill the number grid so that each allowed number appears exactly once in every row, column and outlined box.

How to work it out

  • A 4 × 4 sudoku uses 1 to 4 and 2 × 2 boxes. A 6 × 6 sudoku uses 1 to 6 and 2 × 3 boxes.
  • For each empty cell, check its row, column and box together. Enter a number only when it is certain.

An example, step by step

A row in a 4 × 4 sudoku contains 1, □, 3, 4.

  1. The allowed numbers are 1, 2, 3 and 4.
  2. Only 2 is missing from this row.
  3. Check that 2 is not already in the column or box, then enter it.

Understand other variations

Several gaps

Consider the possible numbers. A number can also be certain because only one cell in a row, column or box can still contain it.

Your turn

A four-cell row contains □, 4, 2, 1. What is missing?

3. In the full sudoku, check the column and box before entering it.
