Use a smaller 36-cell grid with digits 1–6.

Portrait game
The menu calls this setting Kids. It is a smaller practice grid, not an age-verification feature or a separate child-directed service. The ManyPlay service remains intended for users aged 13 and older. A 6×6 board uses digits 1–6 and boxes of two rows by three columns; do not apply the 9×9 box size to it.
Starting a different board can replace the current unfinished puzzle. Read the confirmation if you have already made moves. Undo and candidate notes belong to the active puzzle, not every board in the catalogue.
The illustrated rules page contains the checked 9 placement, hint-counter change and reload example. A finished deal, a midnight rollover and physical-phone printing are not certified by these opening checks.
Play classic 9×9 Sudoku with four difficulty settings, Notes, Undo and explanatory hints. Each row, column and 3×3 box must contain the digits 1–9 once. Choose a smaller 6×6 practice board or open the dated daily puzzle, then compare candidate marks with completed entries.
Choose Sudoku for deduction from fixed numerical constraints. Compare it with Feudaly for one-per-region placement or Powderlab for sorting visible layers; they are different rules, not Sudoku variants.
In the checked Easy puzzle, row 4 contained 8,3,7,4 and 5. Its eighth cell was empty. The Hint explanation named 9 as the only digit that fitted. Another puzzle may start with different clues.
Play in your browser. No app download is needed.
Fill the 9×9 grid with 1–9, with each digit appearing once in every row, column and 3×3 box. Starting clues are fixed. The 6×6 practice mode instead uses 1–6 and 2×3 boxes.
In the checked example, Hint explained that only 9 fitted the highlighted cell. The counter changed from 3 to 2 when the explanation opened. Place then entered 9. Undo restored the empty cell, but did not refund the hint.
No. Notes write small candidate digits inside a cell. They express possibilities, not a completed placement. Turn Notes off to enter a full-size digit; Undo can reverse either action.
A normal page reload restored our placed 9, a candidate 2, elapsed time and two remaining hints in the same browser. This is local storage, not a promise of cross-device or permanent account saves.
The browser menu has Easy, Medium, Hard, Expert, Kids 6×6 and Daily. Daily displayed 29 October 2026 in the check. A midnight rollover and a complete manual win were not verified.
