Tips to play better
- Look for a box, row or column that is almost full: the missing digit often has only one place left.
- Pick a digit and check all nine boxes for it; highlighting shows where it already sits.
- Pencil marks are cleared for you when a digit lands, so jotting down candidates costs nothing.
- A hint reveals the selected cell, or the easiest next step when nothing is selected.
