Nice puzzles, Swaroop!
Thanks. I am glad you enjoyed. But to let you know its 80% Hemant contribution and just 20% mine. So I believe he deserves all the credit. : ) |

A big thanks to Hemant and Swaroop for an enjoyable test.Broke the diagonal 9*9 very badly and took way too much time on it.. The quadruple 6*6 and the diagonal 9*9 were my favourites.Nice,challenging test. |

Interesting to note that both untouch puzzles were effectively also only half a puzzle each, given grid symmetries. |

I was pleasantly surprised seeing my rank.I thought I started really bad when I struggled so much on the quadruple (9 ) which I initially assumed to be a 3 pointer for some reason . I was wondering what was going on with me.After guessing in it,I found the logic that I missed, somewhere in between and noticed the points too through the corner of my eye.Somewhat reassured with that,I did fast on the rest and things started going really well in the middle of the test.Finished the high pointers with relatively less effort. My favourites in order are Diagonal (12 ) (there was one particularly deduction involving 37 pencil mark in boxes 3 and 9.Don't know if it can be solved without that but the logic was super cool ),Untouch (14 ) , Quadruple (7 ) and palindrome (12 ) I really enjoyed taking the test!Well done Swaroop and Hemant!!Set was really awesome. |

Really a good set of puzzles. I really loved the mini quadruple. One thing I must mention is that the answer key could have been better identified. Not sure about others but for atleast 5 of the puzzles, I got the answer key while only half the puzzle had been solved. |

A really good round. Even though untouch had 50 % higher weightage, i solved it at a better pace compared to quadruple 6x6. Overall my favourite is the palindrome 9x9 and diagonal 9x9. |

Country : India | For a change I started with high pointer variants (9x9 grids) this time. Successfully completed 9x9 Diagonal and then took 9x9 Untouch, which probably was a wrong choice, I guess, as I wasted lot of time looking for a break. Got the 9x9 Extra Region easily and was on the way to finish the 9x9 Palindrome, but unfortunately made an error and lost it completely. With last few minutes remaining then I decided to pickup some points with 9x9 Classics. Barring my poor performance, I found the set really good. After the contest, I solved 6x6 Quadruple which to my surprise was created with superb logic and was substantiated by high point attributed to it... Thumbs Up to the Authors .. Hemant and Swaroop. |

The one thing I disliked was that there were two antisymmetric puzzles in this set: Untouch 2 and Extra Region 2. They are never enjoyable to me, because any deduction for one digit is also automatically true for another digit on the other side of the grid. |

Really nice set of sudokus. My favourites are: Extra Region 9x9 Diagonal 9x9 Quadruple 6x6 Thanks Hemant and Swaroop. Excellent stuff!
One small feedback on formatting: The extra region shaded cells are too dark in my printouts. |

Thanks to LMI for giving me this opportunity. It was a lot of fun creating the Sudokus. From the set my personal favourites were 6x6 Quadruple and 9x9 Untouch. And the Quadruple actually got most attention out of the entire set :P
Also thanks to Swaroop. It was a very nice experience of authoring with you. Apart from the sudokus you created, you also helped me a lot in making my creations better by your suggestions :) |

Country : India | Congrats to top 3 overall as well as Indians. It was great experience supporting Hemant. Its so good to see youngsters rising in solving and creating.
Sorry to Hemant if I was too strict mentoring(rejected lots of his creations) just wanted him to learn as much possible and create a good round.
I was very much aware of the half solve of Untouch 9x9 due to symmetry, but I let it through because I like his design and idea. Thanks to LMI for the opportunity and all testers.
Thanks to all participants and their feedback, will surely keep that in mind during next contest. I hope you all enjoyed.
Any participant if they feel they could not solve any particular sudoku, please feel free to post here we will be happy to help you.
Good luck with upcoming contests. :) |

Country : India | Generally, the 9*9 version carries more points than the 6*6 version of each variant. Is it because of the difficulty level of 6*6 is greater than 9*9? |

The points are an indicator of the level of difficulty of the sudoku. So, yes; the 6×6 carries more points because of difficulty. |
