Location: India | I didn't solve it during the test, but I did it quite quickly later considering the points value. My initial steps included getting the possibilities for the 0s, the 2s, getting the 2 diagonally touching 1s in the two middle rows, and figuring out that there have to be 2 1s in either of the boxes at R2C2,R9C2,R2C9,R9C9. My first digits entered were mostly using the middle regions and not the corner regions though, and mainly I could narrow it down a lot in the middle bottom region. I guess you'll be able to do that since thats the least confusing part and all the extra cells are clustered away from the middle regions. |

except non-consecutive. Can someone solve the first few numbers (around 8-10) logically?
I will post the first part of the walkthrough for this mean puzzle tonight, when I am home.
It is the highest points puzzle, compared to size, which is the reason that it has a bit of a tough start. |

OK
Here it is:
R5C5 = 1
R6C6 = 1
R8+R10C5 = 07
7 in C2 locked in R1 or R3
R5C3 = 7
R8+R10C6 = 29
R7C6 + R6C7 = 35
6 in R6 locked in C135
R6C5 = 6
R5C1 = 5
R7C5 = 3
R7C6 = 5
R6C7 = 3
R6C10 = 2
R6C8 = 5
R6C3 = 0
R3C5 = 2
From here it should run smoothly.  |  |

Talking about favourite sudokus, Low Digits was incredible. It was like 'Wow, this can't get better' after I solved it. It was beautiful. No wonder it's average rating is 9.5 from 10 votes.
I noticed the very high rating. Although I am very happy with the ratings of all puzzles, I wonder why especially this one is by far the highest. Is it the shapes of the irregular areas? Or the straight forward solving path? I am very fond of symmetry, in shapes, grey cells and patterns of given digits. The fun part is that this is the only puzzle where symmetry is not possible in the grey cells. |
