Your turn first
Where can the 7 go?
Look only at the highlighted box. Follow the 7 along its visible rows and columns. Which square is left? Enter the 7 when you are sure, or compare your idea with the hint.
Remember
Scanning is simple: follow one digit into a box. Rows and columns that already contain it cross out the other squares.
