Sudoku 6×6 — easy
How to use this worksheet
- In the left puzzle the first column is already complete. Start with the third row, 6, gap, 1, 3, 5, 4: the missing number is 2.
- The second column of the left puzzle shows only one number, so it is best solved last.
- In the right puzzle every 3 is already printed, but only one 6. Look for the 6s once the other numbers are in place.
- Check both puzzles with the solution page; added numbers appear in red.
What this worksheet teaches
Each puzzle is a 6×6 grid with six boxes of 2 rows by 3 squares, and every row, column and box must hold 1 to 6 exactly once. Twenty-four of the thirty-six numbers are given, so each puzzle has twelve empty squares and one correct solution. Every empty square can be solved by checking its row, column and box.
Start where the grid is fullest
A row, column or box with five numbers filled gives the sixth immediately. After placing it, look again: the new number may complete another line nearby. Solvers call these easy wins "singles", and on this easy level the whole puzzle can be finished with them.

Questions from parents
Is this easy 6×6 number sudoku a good first 6×6 puzzle?
Yes. Twenty-four numbers are given, and every square can be solved by checking its row, column and box.
Why does one number appear six times but another only once?
Numbers are removed at random while the puzzle keeps one solution; in the right puzzle all the 3s stayed.
How long do these two puzzles take?
It varies a lot. Let your child work at their own pace, one puzzle per sitting if needed; speed comes with practice.
