How do you play Mini Sudoku?

Fill the 6×6 grid so every row, every column and every outlined 2×3 box contains the numbers 1 to 6 exactly once. Tap a cell to cycle numbers, use the number pad, or type with your keyboard.

Is there a new Mini Sudoku puzzle every day?

Yes — a new daily board goes live at 00:00 UTC, the same board for every player worldwide, with streak tracking. Unlimited free play in three difficulties and a full archive of past dailies are also free, with no account and no ads.

Can Mini Sudoku be solved without guessing?
