First step - add in all possible valid pencilmarks.




Number 6 is the only value possible in cell (5,3).









For row 5, number 1 is only possible in cell (5,5)









For column 4, Number 9 is only possible in cell (4,3)









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









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









For row 4, number 7 is only possible in cell (4,4)









For column 7, Number 7 is only possible in cell (7,8)









For row 5, number 2 is only possible in cell (3,5)









For row 4, number 2 is only possible in cell (6,4)









For row 8, number 2 is only possible in cell (5,8)









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









Number 4 is the only value possible in cell (5,2).









For row 7, number 2 is only possible in cell (9,7)









For row 1, number 2 is only possible in cell (1,1)









For row 3, number 2 is only possible in cell (8,3)









For row 8, number 5 is only possible in cell (2,8)









For row 5, number 4 is only possible in cell (7,5)









For column 7, Number 9 is only possible in cell (7,2)









For row 1, number 4 is only possible in cell (9,1)









For box 9, candidates for 9 are all in row 9, so you can remove candidates from other blocks.









For box 5, candidates for 5 are all in row 6, so you can remove candidates from other blocks.









Naked Pair for 3 and 5, can remove these as candidates from other cells.









For blocks 1 and 4, candidates for 3 are all in the same two columns (2 and 1)









Either candidate for cell (3,2) forces 3 into cell (8,5).









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









Number 6 is the only value possible in cell (7,1).









Number 3 is the only value possible in cell (2,1).
