I'm stucked with this one
Drawer gives the following hint:
r1c8 = 5
I dont see why tho it cant be 5 in r2c8
-843--9--
3-9-1---8
1-689--32
--1-8--9-
--25498--
9481-35--
8-3-561--
415278369
--7-31-85
Thx! |

In box 5 (r4c4-r6c6), 7 can ONLY go on row 4. So you can eliminate 7 from the other cells in row 4. After this, in box 4 (r4c1-r6c3), 7 can ONLY go in row 5. So you can eliminate 7 from the other cells in row 5. So, eventhough r5c8 started with the possibility of 1 and 7, 7 can be eliminated, leaving only 1.
To me, that's the next logical step. |
