How to play Sudoku
Place the digits 1 to 9 once in every row, every column and every 3×3 box outlined in bold. The daily puzzle is a quick 6×6 with 2×3 boxes and the digits 1 to 6.
Tips
- Pick a digit and look for the one cell in a row, column or box where it can still go.
- Turn on notes for tricky cells. When two cells in a row, column or box share the same two candidates, those digits can’t go anywhere else in it.
