Medium sudoku

Medium puzzles start with 34 of the 81 numbers already in place.

Fewer cells give themselves up at a glance, so you'll spend more time comparing what a row, a column and a box each rule out.

This is where Notes start to help. Pencil in the two or three candidates for a cell and let them narrow down as you fill in the numbers around it.
