Are there any hints to solve Quadro Sudoku. Stuck at practice booklet 6*6 variation.
Hi
I think the trick is to find the cells which can be only odd/ or only even but we don't know the digits yet.
Here are steps which I followed:
1) getting 1's - Trivial steps - you get 1 at r1c3,r3c4 and r4c1
2) Now lets see which cells have to be odd - r4c2 and r3c5 has to be odd as 2,4,6 can't come there.
3) Now notice r2c4 r2c5 r3c4 r3c5 forms quadro and out of which we know three of them are odd and hence r2c4 will be even.
4) This implies r2c4 is 2 and r2c6 is 3.
so you can keep putting which cells are known odd or even, which will help to avoid 2*2.
Not giving complete solution as these are few starting steps which will get you started. You can post again in case you are stuck at some point.
Enjoy :) |

Location: India | Somehow I missed step 3. I started at 9*9 and was able to solve it. After that my eyes could see step 3 in 6*6 and I am able to solve.
Thanks a lot for your efforts and such a nice explaination |

Thanks, Deb !
I knew my black cartridges were empty and that I would have some problems soon.... It was today :( . Fortunately the online solving was enabled. So, tanks for the online solving too :)
I have no idea if I could have made a better time with my plan of solving the 9*9 variants on paper.

Yes, it's planned. My problem is that when my printer tells me that the cartridges are empty, it's far to be true, I can still print a lot of sheets until it doesn't print correctly. So I prefer to wait until it's really empty, hoping there is no sudoku tournament that day ... |
