This blog deals with grid-based puzzles and the various types of logic and ideas used to solve them. It also contains notices, information and results about various puzzle and sudoku championships across the globe.
If you could not figure out the logic, then it is not a nice Sudoku.
I created this long time back, and obviously don't remember the logic. Found that I could open easily with following. C6=1 C4=8 F5=1 G2=1 A7=1 Then it takes a while to find F7=9 H3=9 D5=9 A4=9 C2=9 F1=8 Then E4=6 can be found. After that it is mostly like a classic.

How long did you take to solve it?
Post your timings here.
I solved it in 6m 51s.
Couldn't solve it logically though :|

C6=1
C4=8
F5=1
G2=1
A7=1
Then it takes a while to find F7=9
H3=9
D5=9
A4=9
C2=9
F1=8
Then E4=6 can be found.

I guess I missed out on the '9's.
No, it is still a good puzzle!
