One thing is that Scattered 6x6 felt really hard to me (took lots and lots of time, almost comparable to Scattered or Chain 9x9 ), but other than that this contest was great, especially the idea of Surplus. |

Country : Singapore | meowme posted @ 2014-10-18 3:58 PM Ouch. After not doing sudokus for a few months, I broke the surplus 6x6 and 9x9, chain 9x9, two standard 9x9s and the standard 8x8. The solves were all good, but the toroidal was particularly amusing :) At least I quickly could tell that I didn't break it... |

R1C6 and R2C4 are in the same region and you have two 5s. So there's one mistake. I just solved the puzzle fine. |

Thanks Prasanna, mistake was from my side, I could not proceed logically after putting some number for this Sudoku. Making a guess lead me to different solution and I did not realize that same numbers fall on same regions.

Country : India | i agree with rakesh that surplus sudoku was the tougheest . i also found the 6x6 scattered sudoku tougher than the 9x9 scattered sudoku. i goofed up the chain sudoku , else i would definitely be getting bonus points as i still had 5 minutes even after messing up the chain sudoku and submitting the rest of the answers. |

Another SM episode with a brilliant set of sudokus.My favourites of the lot were Scattered (10 ) wherein I admired the way the scattered cells were constricted within the middle 3 columns which in turn forced a lot of quick deductions and the Ir-regular (11 ) My entire solve duration of 67 minutes was split into 3 sessions.The first session was consumed by the chain sudoku (3 pointer )for 7 minutes.The next session ,where to shrug off the poor start, I increased the pace without worrying about accuracy and completed the rest except the chain (17 points )without any errors by 54 mintues and the final session where after submitting the answers of the middle lot during which I took a bit of breather, I focussed intensely on the last chain assuming it to be very difficult.It was indeed difficult and consumed close to 15 minutes but had a very lovely solving path. Just like the others,I too found the smaller pointers a bit more venomous than their worth.For instance the scattered and the surplus lower pointers were hard to solve for me. The test itself was excellent ,taillored well to fit the 90 minute slot.I had great fun solving the puzzles. Thanks a lot Rohan Rao aka R^3!! for a beautiful test. :-p |

2. Which other tests did you have this problem, if you can recall?

The standard 5-pointn sudokus did not seem as well representative of their difficulty when compared to each other. |

The solve it online was a big help. But I wonder why when I submitted on online tool accepted my answers but the solutions were not accepted on the server. Is the solver submittion taken on a seperate track? |

The solve it online was a big help. But I wonder why when I submitted on online tool accepted my answers but the solutions were not accepted on the server. Is the solver submittion taken on a seperate track? I am not exactly sure what you mean. I see that you have submitted six sudokus. Three of them submitted using online tool - 6X6 Standard Sudokus 2,3,4. Three other sudokus are submitted using textboxes meant for paper solvers - 6X6 Standard Sudoku 1, 9X9 Standard Sudoku 1, and Irregular 6X6 ). Both kind of submissions are accepted and shown in the score page.
While LMI does not recommend which mode to use, you can choose between "online solving mode" or "paper mode" or mix of them to solve and submit the sudokus. |

Country : India | vopani posted @ 2014-10-22 1:35 PM Congrats to Jakub Hrazdira (Czech Republic), Kota Morinishi (Japan) and Hideaki Jo (Japan) for the top-3 spots in SM Round 2: Irregular Variants.
Congrats to Kishore Kumar, Rakesh Rai and Prakhar Gupta for taking the top-3 Indian spots. Kishore, having topped both rounds of SM comfortably, is way ahead of the rest. Good show.
Being one of the last ones to pick a round, it seems Indian authors don't enjoy creating Irregular Sudokus ;-)
Irregular is not a very comfortable type for a lot of Indians (and maybe others too?), so my approach was to create really easy Classics so that players can spend more time on the variants.
Thanks to Prasanna, Swaroop and Rishi for testing/pre-solving the set.
A lot of players seemed to struggle with the 9x9 Surplus, well, it had a strightforward solving path. Maybe it was slightly under-valued.
The 6x6 Scattered was my personal favourite of the set, and it has a neat little trick of solving if you spot the fixed positions for the same number.
The original 9x9 Chain was too hard and it was replaced by a pretty cool one (which incidently, is Deb's). I was confident this would be the highest rated sudoku of the set.
Participation was lower than SM Round-1, just about 300 participants and a little over 100 Indians. Why? Don't like Irregulars? :-)
Anyway, hope to see you all in SM Round-3 (Odd-Even Variants by Deb Mohanty), which promises to be fun with high-quality puzzles and hope to see more participation.
If anyone found any variant particularly difficult to solve or is interested to learn how to solve any sudoku of this set, feel free to post here. Some of the active puzzlers in this community will be more than delighted to share solving techniques and logical steps to solve these sudokus :-) |

Sure...
In the surplus sudoku from this competition it works really well. The four "outies" are exactly the four doubled numbers in the four regions that are before the line of cut. |

That was fun to watch! Though, I wonder how you put the 1 and 6 in Row-2 for the 6x6 Surplus right at the start?
Maybe one of the top-10 players should record one of these. And imagine if we could also have some brain-capturing technology that shows visualizations of what goes on in their brains :-)
I hope technology progresses really fast ;-) |

That was fun to watch! Though, I wonder how you put the 1 and 6 in Row-2 for the 6x6 Surplus right at the start?
I don't remember what was my thinking ,I now see that the 6 in the first area can only be in r1c1 or r2c1, then 6 is in r6c3 and in r4c6, then 6 can not stay in r2c6 then is in r2c1.
But I saw that I was quick to put it but do not put the other easy 6 in r6c3 and r4c6 then i think it was a lucky mistake because it was my absolute first sudoku surplus... |

Country : India | I loved solving the Chain Sudoku. It was exquisitely designed. Kudos to Deb, looking forward to an exciting Odd-Even round authored by Deb.
I liked the design of all big pointers, kudos to Rohan ! Nice round !! I like Jigsaws, it sounds synonymous with Jurassic somehow. |
