First step - add in all possible valid pencilmarks.




Number 1 is the only value possible in cell (3,4).









Number 2 is the only value possible in cell (1,4).









Number 5 is the only value possible in cell (1,5).









Number 3 is the only value possible in cell (3,6).









Number 7 is the only value possible in cell (2,6).









Number 8 is the only value possible in cell (2,5).









Number 2 is the only value possible in cell (6,6).









Number 1 is the only value possible in cell (9,6).









Number 5 is the only value possible in cell (7,6).









For column 2, Number 2 is only possible in cell (2,1)









For column 9, Number 2 is only possible in cell (9,3)









For column 4, Number 3 is only possible in cell (4,8)









For box 7, candidates for 5 are all in column 2, so you can remove candidates from other blocks.









Naked Pair for 4 and 5, can remove these as candidates from other cells.









Naked Pair for 1 and 6, can remove these as candidates from other cells.









Naked Pair for 1 and 6, can remove these as candidates from other cells.









For blocks 7 and 8, candidates for 1 are all in the same two rows (7 and 9)









Either candidate for cell (4,4) forces 1 into cell (7,8).









Either candidate for cell (4,4) forces 3 into cell (2,2).

Number 8 is the only value possible in cell (6,3).









Number 5 is the only value possible in cell (3,3).









Number 8 is the only value possible in cell (3,1).









Number 4 is the only value possible in cell (3,2).









Number 7 is the only value possible in cell (8,3).









Number 6 is the only value possible in cell (9,1).









Number 8 is the only value possible in cell (7,2).









Number 3 is the only value possible in cell (5,3).

Number 6 is the only value possible in cell (3,8).









Number 2 is the only value possible in cell (5,8).









Number 9 is the only value possible in cell (8,8).









Number 4 is the only value possible in cell (2,8).









Number 3 is the only value possible in cell (1,9).









Number 9 is the only value possible in cell (2,9).









Number 5 is the only value possible in cell (5,9).
