In scattered " each digit appears exactly once in each row, column, outlined region " and grey cells or no?!
If the given rules are followed the grey cells part is forced, unless there are more than N grey cells in an NxN grid ; ) |

1. Last year's IB and PB had different layouts.
2. We are not creating new puzzles for IB. So, this year's IB has same puzzle as previous years. This is true for all episodes.

I expect this to be moved to another thread since it has nothing to do with Irregulars. In the future you can just create a new topic in he General discussion forum to ask such doubts.
For this particular one, there is only one shaded cell I can see where a 6 can be placed. Maybe that helps? Also there are some nice tricks in eliminating digits from R5C5. It can't be 2 because it forces a 2 in R2C4, can't be 5 because it forces a 5 in a shaded cell in box 6 and can't be 4 because it forces a 4 in R8C6 (noted before you place the 6 there ) |

An excellent,testing and a hard set.I had tremendous fun doing this test.With 20 mins to go for the 16 point instructionless,and having figured out the rules,I was confident of finishing it comfortably.But it turned out to be incredibly sticky and I had to put too many pencil marks before getting it right.Towards the end,there was a lot of panic as the timer began to slowly go under the 5min mark.I was almost sure that I would end up broken but thankfully there were no errors.It felt great to complete the set.A hard set but a really good set of sudokus. My favourites were the Classic (10 ),and scattered (12 ).I enjoyed solving the rest too but they gave a bit more trouble than I would have wanted.So that concludes SM with a beautiful set to complete it . Looking forward to the offline finals and hopefully to attend it and meet like minded people : ). Would love to know the individual contributions by the authors !Thanks for the fun test!

Lots of aha moments in this fun collection, even in the classic sudokus. I usually leave the easy 6x6 puzzles until the end for spare minutes but I was working the first instructionless until nearly the last minute...someday I shall finish one of these. |

I think the only problem was the location of the answer keys. In the 2-nd 6x6 classic the answer key column was the first column I solved there. I actually solved taht column + 4 other digits in the grid. |

Some of the classic Sudoku puzzles in this test were far more difficult than the assigned point values, and indeed more difficult than some of the fancy variations. I felt the variants were good though; no complaints in this section. |

I felt the 6x6 ones (and 8x8 one ) were fair, but the 9x9 ones were too tricky for their value. I usually don't have any problems with the classic 9x9s so was surprised here by this. |

I like Instructionless the most. I couldn't solve it in time, but after the test I enjoyed it so much. Good techniques were used in both of them. |

I crashed the toroidal sudoku, loosing 13 minutes between trying to fix my mistake and solving it entirely again after the first strategy wasn't successful.
Thanks for the whole sudoku mahabharat series, it was fun, even if designed first for indian players.

Very nice puzzles, but felt its on the harder side. Really liked some of the solving paths here... top quality puzzles. My favourites were both the Instructionless ones and the Scattered 9x9. |

Country : India | It was a wonderful experience creating sudokus for the test. Thank you so much Deb for giving me this opportunity. We had very less time (approx 10 days) to finalise a lot of things . So this is what we could actually come up with . I am glad so many participants liked it. Deb has made a mistake by crediting me with instructionless 9x11. It was 90% his effort and 10% mine. I would also like to thank Ashish Kumar for actually making me believe that I can create Sudokus when I had just started creating. Thanks Ashish . |

Country : India | It is good to see that many indians are not only improving themselves in the solve but also in the authoring side. Many indians have contibuted their puzzles for the first time in SM and the response was quite impressive. I believe its because of the passion they have for puzzles which takes them to such a level. Same passion I saw in Akash and it was him who took an effort to get into creation side and achieved this level. I did nothing to make him create but just his interest towards creation was more than the motivation from my side. |

Really nice contest. I didn't really do that well, I just missed too many easy deductions on the day, but I still enjoyed it. Its really nice to see a new author emerging during SM and not only that but taking on the responsibility to contribute a significant portion of the round. Well done Akash, and also Gaurav, the other first time author. I thought the two Scattered Sudokus had some lovely patterns and logic and thats my favorite section. Amit's one contribution was really nice too :P All in all, a great way to end the online segment of SM. |

Country : India | Added note - The fact that 35 solvers finished shows me this wasn't too hard. I think Irregular variations take more practice and exposure to get used to and so beginners will feel they are tougher (i.e. the difference between an experienced solver and a beginner is probably more pronounced here). There are also a lot of implied deductions that come with irregular areas and in-out strategies and so on. I encourage beginners to ask about specific Sudokus where they're stuck in this round, there may be unfamiliar insights which help in the future. Also, very well done to Rakesh, that's an impressive result! |

Country : India | Thanks for all the feedback. It will surely keep us going and in future we would be able to do more contributions.
For me the hero of the show is DEB, He has just amazing amount of patience with us and nice suggestions that it improved us (Akash will agree with me surely :) ) to this level where everyone is appreciating us. Deb thanks for all the support and the work you do behind the scene is commendable.
Another one is definitely Akash who has done tremendous job and is major contributor in this episode.
Creating a simple Sudoku was distant dream to me until we had Sudoku meets and there all of you (Prasanna, Rohan, Amit, Deb, Rishi) helped all of new comers like me.
Prasanna thanks for giving the chance to contribute at this stage and believing on me throughout.
Thanks all participants and Congratulations to Rohan, Rakesh and Kishore for impressive performances and taking top 3 positions in India. Congratulations to Tiit, Jaku and Janoslaw for taking top 3 positions overall.
Looking forward for more contribution in future.
