Sudoku Kids
Tap a square, then tap a digit (or press 1–6; Backspace clears). Every row, every column and every 2×3 box must contain 1 to 6 exactly once. Digits that clash turn red. Solve it for points that shrink with time; each new puzzle has fewer clues, down to 12.
Sudoku Kids — a free online arcade game on TotType
Sudoku Kids is real sudoku at a child's size: a 6×6 grid split into 2×3 boxes, so every row, column and box needs the digits 1 to 6 exactly once. Tap a square and a digit, or type. Any digit that clashes with another in its row, column or box turns red immediately — the rule is taught by the board rather than by a lecture — and given clues are white while your own entries are blue. Puzzles are generated with a single solution; the first has 22 clues and each one you solve removes two more, down to 12. Solving pays points that shrink with the seconds, so the total rewards both logic and pace. It's free in any browser with no download — anyone can try a demo run with no account, and a free parent account with a verified email unlocks unlimited play.

How to play Sudoku Kids
Tap a square, then tap a digit (or press 1–6; Backspace clears). Every row, every column and every 2×3 box must contain 1 to 6 exactly once. Digits that clash turn red. Solve it for points that shrink with time; each new puzzle has fewer clues, down to 12.
Tips & tricks
- Start with the row, column or box that already has the most digits — the missing ones are nearly forced.
- Tap a filled square to highlight every copy of that digit; the row and box it is missing from show up at a glance.
- Red means a clash right now, not a wrong guess forever — change one of the two and it clears.
Frequently asked questions
How do you play Sudoku Kids?
Fill the 6×6 grid so every row, column and 2×3 box contains 1 to 6 once each. Tap a square, then a digit from the pad — or use the keyboard: 1–6 to enter, Backspace to clear, arrows to move.
Is 6×6 sudoku easier than 9×9?
Much. With six digits the logic is the same but every step is shorter, which makes it a good first sudoku for children. The puzzles here get harder as clues are removed, so an older child still gets a challenge.
How is it scored?
Each solved puzzle is worth up to 600 points minus 2 per second (never less than 60), plus 50 per level, and the total keeps climbing across puzzles. With a verified account every solve posts your total to the arcade leaderboard.
