Mini Sudoku

Fill every empty cell so that each row, each column, and each bold box contains every number exactly once — no repeats.

Tap a cell to select it, then tap a number to fill it in. Toggle Notes to pencil in candidate numbers instead of committing a value.

Cells that conflict with another cell in the same row, column, or box are highlighted so you can spot mistakes immediately.

Hint fills in one correct cell but counts against your score. Undo/Redo step through your move history.

Practice mode lets you pick 4×4, 6×6, or 9×9 and any difficulty. The daily puzzle is a 6×6 board everyone plays together.
