Country : India | We will be organizing the Indian Sudoku Championship online on 11th August 2013. (not to be confused with any other offline event that might be conducted in a similar time-frame)
The winner of this event will be regarded as the national champion as it is a fair event which is open to all participants across the country.
Participants who are among the top few in this championships will be invited to participate in the World Sudoku Championship in an individual capacity.
Unfortunately we are not in a position to bear the participation expenses for the winners who are selected through this event. However I hope that we will see a large number of participants, each vying for the pride of being called the national champion.
We will post additional details regarding the event in coming days.

Yes, we can work out the formation of B -teams, if we have enough participants |

Thats neither easy to do, nor fair. I'm sure the organizers will try to make it online-accessible, but for one thing, "no printing and paper solving" is unfair on those who have a printer and haven't got a great net connection, and also those who have mouse/keyboard related issues. The most ideal format will always be to have both paper solving as well as online solving enabled.
For another, the organizers are now managing 2 events (TSC and ISC ) on the back of another event (IPC ), so in general, I'd suggest to value the effort put in rather than nitpicking over the little things. |

Country : India | If it paper solvable results will not be fair. Can take a few copies and two or three can solve each one and combine submit the answers. Regarding net connection today almost 80% areas are covered by reasonable network, so this wont be an issue. As LMI has already developed required grids, I presume no difficulties to enable only online solving mode which will be very fair. |

Online solving is totally different in comparism with paper solving. Online solver will be in disadvantage at WSC and probably, the goal of ISC is to choose the best participants for WSC. |

Hi, With much more bigger things going on and as stated by Prasanna do not nitpick/debate on method of solving. LMI is very much experienced in these things and they exactly know what they are doing. Even if someone cheats LMI can find that, they have their own methods. So prepare well for the competition and give your best  Regards, Ravi |

As LMI has already developed required grids, I presume no difficulties to enable only online solving mode which will be very fair.
And online solving can't have two people simultaneously opening the interface, and sending answers simultaneously? There's always ways to try to cheat the system, if you think like that. But you can be rest assured (as mentioned above ) that any suspicious results will be checked by LMI, just as they are in any other tests (I don't know if you've ever noticed the "D" that appears next to some participants in usual LMI contests ). If something's really suspicious, there are ways to find it out, and you need to trust the organizers to do so, and make sure you are enjoying the competition honestly from your side.
Your arguments are inspired with a slightly different goal to holding a fair contest, I feel, and so your arguments don't really take in everyone's opinion. The fact that you dismissed the net connection factor by saying "80%" and not worrying about the other 20 shows that. Also, think about whether "having a net connection" equates to "having a stable net connection that'll last over 2 hours". You didn't even address the other issues I put forth (mouse/keyboard issues ). There's a panel of organizers here to judge any suspicious results. Lets stop thinking about that, and prioritize having the test accessible to 100% instead of 80%.
Also, what do you mean by "As LMI has already developed required grids"? I don't think they've released the progress of the event planning anywhere. If you mean they've developed required grids in the past for the interface to work, how do you know that all the variants for ISC 2013 will be interface-friendly? As someone who has been an author for other country National Championships, I think you're greatly underestimating the effort and planning put in to organize these Championships in general. |

Hi
There are two ways of solving the sudokus in Indian Sudoku Championship 2013.
1. Online mode - You will have a Flash interface with the grids where you can solve the sudoku online and click submit button, which is present in the bottom of each sudoku. So you can click the submit button immediately after you finish each sudoku.
2. Offline mode - You need to take printout of the Puzzle booklet. Solve it offline and there will be marked rowa/columns in each sudoku. (Either two rows/two columns/one row and one column ). Enter the digits of the marked rows/columns in the Text box provided for each sudoku in the Competition page. Then press Submit button present in top of the Competion page just above the text boxes.
All these details are explained in the link present in Prasanna's previous post. Please go through the link once more and also navigate the site and forum. You will get more details. |

No. You cannot do it. You will be able to open the Password protected booklet once you click "Start the Test" button. The Timer will start once you click the button. You will be wasting time if you go out and take printout. It will be better if you solve in Online mode. |

The ISC will also be extended for 48 hours from the start to accommodate all international participants.

Typically it is expected 5 days before the event. The IPC IB was released in that time-frame, so I assume this will be too. I assume as soon as the Instruction booklet is ready, the organizers will post it. |

Country : India | 2 things -
In overlapping Sudoku - Do we assume that the overlap will be "clean" like the IB example, or is it possible that it will cut into boxes? (e.g. I think the one at the WSC in 2012 had just 2 rows/columns that weren't overlapping, instead of 3 as in the example)
Answer keys - Again, in Overlapping Sudoku, I assume that the non-overlap parts will also need to be entered, making the key possibly longer than 9 digits? Also, in Smashed Sums Sudoku, how should the black/blank cells be denoted in the key?

Country : India | Hie there are grey/dotted lines, grid lines and areas in following sudokus : Killer, Renban ,Thermo, Arrow, Vudoku, even killer. So can I expect them little darker in actual puzzle booklet, as they are not visible on printing on paper. Especially vudoku and arrow hard to see. So if it possible to make it darker then it would be helpful :) |

You have to find the black cells. On the left you will find a sum of 28, which means the black cells for that row are in C1 and C9. You can go on from there.

Four participants were selected from the Times Sudoku Championship. We expect them to do well in the ISC too.
We will be looking for the top 4 apart from those who have qualified from TSC.
We will also be considering exceptional performances by some newcomers, who could benefit from the exposure of a World Championship.

Well, you may have to search for the exact variants related to the ISC, but there is a lot of practice material on this site. LMI conducts regular Beginners' Contests and Monthly Tests. Look through the test links/ PDFs in both those links and that should be more than enough to practice. If any doubts/queries regarding a particular Sudoku, you can always post that here and one of us will surely help. |

I think this is there for a reason. You can mark black cells with X and mark a . for where you think a number should be (as in, not black ) and that marking will certainly help in solving this one. |

what is sudo-kurve?not getting it.
There are 9 distinct digits in each 3 groups of 3 cells that are connected by gray lines. Example of this - The first row of the top left box, the 3rd column of the middle box and the first row of the bottom right box are connected by a bending gray line, and so there need to be all digits from 1-9 in those 9 cells. |

I suppose it is more of a free-form type but the range will always be 1-9 as in the example. The example has just 3 boxes, but it has in all 6 different sets of 1-9 as Ravi pointed out. If you google Sudo-kurve you'll see many other possible layouts, the base theory in all being that there are such sets of 1-9 formed by the connecting gray lines. |

If there is no clue, it just means there is no restriction on the shaded cells in that row / column. They could be adjacent or not be adjacent, in that row / column.

Deepika, not all sudokus need to be 9x9. There are so many variants which do not conform to this design. For example, Isosudoku, Snowflake sudoku. The only constraint we need to remember is that the digits do not repeat along the path denoted by the grey lines.

One question related to 6x6 Sudoku point distribution. Will the 100 points given only when all the 6x6 Sudoku solved correctly or each given mini Sudoku will have some points assigned to it?
They are all independent of each other. Points are assigned to each of them. You get points for what you solve.
If you have logged in at the submission site, you would have noticed that there are 6 of them, and the points are as shown below.
(Top ) 5 + 10
(Middle ) 15 + 25
(Bottom ) 25 + 20 |

Country : India | I had a question on the Bonus points. It says that all answers with a maximum of 4 wrong cells will get the bonus of 7 points per minute saved. Now I assume the 4 cells are related to the answer keys that we key in. So do we get full points for a puzzle if we key in a wrong answer with a digit mistyped or do we get partial points or 0 points for the puzzle yet eligible for time bonus?

Note that, partial points will only be given in exceptional cases (e.g. the typo is on a given clue ) |

One more note about Smashed Sums online interface - Please use the Space key to erase entries. 'Delete' key does not work nicely. |

Please let me know the format of pwd for the pdf shown above for reference
How to get the password?
In previous year's championship, many players were not sure how to get the password. Exactly following steps are needed to get the password for the puzzle pdf.
Note that the "Start ISC 2013" button will be enabled only after 2:00PM.
If the button is still disabled, you need to refresh your browser.

Country : India | In Sudo-Kurve I can see that the answer key is 9 digits long.
I presume that this corresponds to the nine digits along the curve in the direction of the arrow? |

Country : India | i just loved the test, today i was finally confident of solving sudokus though at some case to rush up i used guessings but luckily worked out. Finally i am happy with the number of sudokus i was able to solve. The variants were just awesome and i was able to get logic quickly. At few variants unfortunately got stuck and had to leave it.
Thnks to organizers and the puzzle authors for awesome test.

Country : India | I simply loved the Smashed sums.. which incidentally made me start thrice. Finally when the logic dawned, I could only gape in sheer amazement at the simplicity of the puzzle. Beautiful.

Thankfully that didn't deter things. Amazing quality of Sudokus. The Outside Sudoku was particularly brilliant. Thanks to Deb and the rest of the authors/organizers. |

There should be alarm kind of thing to warn 2 minutes before time gets over. Actually, I m still not sure whether I had to hit that submit button near the clock, I kept on hitting submit button after solving every puzzle but didn't hit the 'submit answers' button near the clock. Also I m not sure whether I had to key in the numbers in that grid of answer keys shown above the puzzle. I had thought that solving puzzle only and clicking on submit button below the puzzle would do. So I guess because I didn't click on 'submit answers' button near the clock, I m not being able to see my score. : ( Otherwise, quality of puzzles were amazing. Really enjoyable. Thanks for the great test : ) |

Hmm, I think your worry is that your answers may not have been recorded. If your query is whether just solving on interface and clicking submit for each Sudoku will do, then yes, that'll do. You don't need to enter in the answer keys as well. You don't need to hit submit again near the clock, unless you have something new to submit. |

Country : India | Right, so my thoughts about individual Sudokus (in order of solving) -
Classic 1, 2 - Sprint. I didn't have any pause moments in either of these. Contrary to points, I finished 2nd one quicker, but I'm weird with classics.
Outside - Yeah, I jumped directly to the Outside Sudoku. This was absolutely beautiful and quite tough. Took me close to 15 minutes, had marked a lot of 7-8 doubles around the left half of the grid. The major break was the 1-2, 3-4 part at the top leftGr after all the obvious stuff I think. There were a few implied doubles and triples forming that were hard to spot.
Greater Than Consecutive - Sprint. The non-consecutive logic makes things very limiting.
Even Killer (try 1) - Disaster! Staring, staring, staring for 10 minutes and getting absolutely nothing. I don't know why, I think I just went blank here. Thankfully, I decided to jump away.
Smashed Sums - 10 minutes perhaps. There's a bit here around the middle 3 columns thats very limiting, once you figure out that either the top box or the bottom box needs to have X-6-X one below the other in the 6th column, its easy to limit where things go exactly. Again, this one would only be solved quickly if one marks circles for cells that can't be black as well.
Vudoku, then Thermo, then Arrow - Sprint. Just used the general sums/difference logic or increasing/decreasing logic, nothing fancy. The Arrow middle part with the 3-5 double for the 8 sum meaning 3-3 can't be there for the 6 is probably the only place where I took a minute to pause and think among all 3 of these.
Killer - Mega sprint. But I can understand it not being so for people not familiar with the in-out rule, as this got pretty obvious with all the 7-9 doubles forming. Nicely constructed and themed on that, I do like solving themes.
Renban Groups - A bit of a symmetric touch to this one, with most of the same logic being used for 1-3-5 and 2-4 to open it all up.
Pinocchio - Nice use of the rules. After getting the 3 in the middle box, you can immediately figure out that if the other 2 fours are true the middle 4 can't be false, so one of those 2 has to be false, and the middle 4 true. After that, pretty easy.
Diagonal - Sprint.
Shifted (try 1) - Mini disaster! spent 3 minutes, got stuck, thought I'd made a mistake, so jumped to Deficit.
Deficit - This was nice. These types are usually easy but this one certainly wasn't. There was a lot of, "ok, this number cannot be in this box so all the other numbers have to be there" and then using the in-outs of Irregular logic.
Shifted (try 2) - Turns out I hadn't made a mistake, but just entered a 5 as a 2 somehow! Thankfully spotted that quickly, and after that easy enough. Major suggestion here would be to focus on the shifted part (rows here) just a bit more than columns/boxes.
Classic 3 - Sprint.
Sudo-Kurve - Although just a slight tweak on the IB design, I've still never seen that exact design before. Was nice to work through, though easy.
Overlapping Sudoku - The part that really speeds the solve here is, from 4th to 9th row onwards and 4th to 9th column onwards, the 1st 3 numbers and last 3 numbers have to be same. Simple implied logic, but really speeds up the process.
Even Killer (try 2) - Not blank anymore! Spotted the 5 odds forming in the 1st column meaning that the rest all had to be evens, and went on quickly from there.
6x6s - Sprint sprint sprint, although I think I paused a little (too much) on the 5th and 6th ones. |

Excellent Grids .Goes without saying given the quality of the authors involved.My personal favourites are Outside sudoku and Killer .Outside sudoku was fun to solve and had some really hard deductions.Finding the hidden single 9 in that in R5C2 was super good.Killer was sweet and simple revolving around the 79 pair. The curious thing about this test from my perspective is that i stumbled and had to take a guess in as many as 3 6 X 6 grids whereas i had no problems in solving logically the 9 X 9 grids.I intend to erase the 6X6 grids that i had guessed and find the missing logic sometime later.I wisely avoided the smashed sums sudoku which looks extremely hard and saved considerable time . Thanks to the authors and the Organisers for a nice test and 94 mins to complete a 150 min test which means roughly 5mins spent for each Grid???Phenomenal !!!!. Also Congrats to the trio Rishi ,PS and Rohan who have interchanged top Positions amongst themselves! |

I enjoyed the session very much. Lost a couple of minutes at the start because firstly, I forgot to click the online button, and also the puzzles took a while to load on the screen. I seem to have made some mistakes, there is a claim message, how does this work ? I don't attempt the other puzzles that appear on this forum, so I do hope the monthly sudoku contests continue in a regular fashion. I would like to give more stars but three seems to be the max.

First query - claim message. If you think your mistake is just a typo, like say you've probably just entered 1 number wrong while entering the key, or swapped rows somehow, then it is a means to bring that to the notice of the organizers. In the end, it is up to the organizers themselves to decide if your claim is valid or not of course.
Second query - Sudoku Contests do continue in a regular fashion. Visit the forum regularly, and you'll know when the next one is. Also, you can always give the past tests a try as a leisure time solve/practice |

The only complaint in an otherwise perfect test was that the 6X6 puzzles which were expected to be most accessible were a bit tricky. The points suggested that they would be difficult, and I used trial to get past them quickly, but that is something which newcomers are not accustomed/keen to do. |

Congratulations to Prasanna for excellent performance and good luck to Indians in Beijing. Ignoring the Screen Test, I think we have to go back 3 years (Mastermind Twins ) which I organized and you participated.
You had spent so much time on Times Sudoku that I really didn't want to ask you to pre-test this one. Thank you so much for being there all the time.
I take this opportunity to thank the authors for providing some wonderful Sudokus.
Classic Sudokus, Sudo-Kurve, Thermo Sudoku, Arrow Sudoku - Thomas Snyder
Pinocchio Sudoku, Diagonal Sudoku, Killer Sudoku, Renban Sudoku - Bastien Vial-Jaime
Smashed Sums Sudoku, Vudoku - Serkan Yurekli
I am indebted to the test solvers - Bram, Gotroch, Matus, Nikola - who gave very significant input and feedback in a really short amount of time.
Thank you everyone for your kind help.

Country : India | Indian Sudoku Championship - Results
The Indian Sudoku Championship is officially over. Both the official Indian Score page as well as the International score page are now public. 15 participants submitted all 24 Sudokus correctly, including 3 Indians.
Congratulations once again to the trio of Prasanna Seshadri, Rohan Rao and Rishi Puri for a strong showing at the top again. Prasanna's score of 1232.7 points was good enough to defeat the defending champion Rohan who scored 1181.2 points. Times Champion, Rishi, had a close 3rd place finish with 1158.1 points. Some good performances from the experienced contenders, Gaurav Korde and Amit Sowani, and Kishore Kumar showing a lot of potential with a solid 6th place, building on his good performances in recent LMI tests as well as the Times Championship. The International top 3 places were taken by janoslaw, Kota and daisuke_t. Prasanna finished at an impressive 6th place in the international rankings.
Thank you all for participating, and please keep visiting the forum for more puzzle contests and discussions.

Country : Switzerland | Fred76 posted @ 2013-08-15 4:39 AM Thanks for having organized a beautiful test.
Having sudokus from different authors permitted to vary the difficulty and styles. I think I recognized some authors' style while solving a few puzzles (especially kurve, renban, vudoku ) but it should have been difficult to "authenticate" authors for all puzzles (I was surprised that the killer was written by Bastien, for example ).
This test was a bit particular for me, because my grandmother died sunday, so I was not looking to make a good result, only tried to think of anything else.
Puzzles created by Thomas were really easy for confirmed players. Kurve, thermo and arrow were very nice for beginners or less experienced players, (as there are many for a national championship ), and a good sprint for others. (I created a lot of classic sudokus last month, so I could not help noticing the lack of symmetry of the second classic, with 2 digits added on the bottom left. I think it was possible to make a symmetric one with that pattern, without adding the 2 digits, but it's really a tiny detail ).
I even didn't notice the theme of the 6*6 irregulars while solving. Nice construction ! Overlapping, shifted and deficit were nice.
Diagonal was a nice construction, with only 18 symetric givens without clue on diagonals and a nice pattern . I liked the logic of killer and renban. I was not fast on smashed sums, but it had a nice logical path, too. GT consecutive had lot of non-consecutive logic in it.
I was stuck for a while in outside sudoku, but that's quite normal as it is worth 115 points.
Like Prasanna, I was stuck in the even killer, but after having spotted the 5 odds in the 1rst column I wasn't able to find the 9 in R3C7, which was quite easy. So I lost at least 10 minutes on that one (I left it and finished to solve it at the end ).
Congrats to Prasanna, Rohan and Rishi, Jan and the "pack of hungry Japanese players" and thanks again to the organizers !

Fred
The second classic has diagonal reflective symmetry which is one I certainly count (others may only like spinning their puzzles in place ). I was indeed going for a clover leaf with an all even middle and an all odd outside but there are no possible puzzles of this form without another even digit somewhere. Making a stem for the clover was my compromise, along one diagonal axis, as that then kept the very naked single start I had set-up fully preserved. Edited by motris 2013-08-16 12:24 AM

You are right, it has a diagonal symmetry. Also, I didn't notice the even-odd "game" on this puzzle. Thanks for the explanation

I even didn't notice the theme of the 6*6 irregulars while solving. Nice construction !
That (the theme ) is also the reason why the 6X6 irregular ones turned out to be tougher than usual, as noted by some participants. Thankfully, they were not in the first page of the pdf. |

Country : India | Sorry to harp back to ISC challenge, but I need some help in solving smashed sums, deficit and shifted sudokus. I am unable to go beyond a point in deficit whereas in the other two, I don't even know where to start. I also need help with the 6x6 of which I could solve only two. The last one in the left side column and all three in the right side column have proved difficult for me. |

Here are the steps for Top Right 6X6 Sudoku.
In the last image here, I use something called "Placeholder". It can be explained like this : Lets say R1C5=X. So X can be 2 or 3 or 5. Then R2C3 = X, and then R5C1=X. Now where does X go in box6, and what will be its value?
Placeholder can be used to solve some of the other 6X6 that you have found difficult. I will be posting steps for them, but it will take a while (to create the images. ) |

Shifted Sudoku is as good as a classic, you just need to modify your region-wise reasoning, and concentrate on rows and columns too. At the start it is advisable to focus a lot more on rows and columns till you are able to adapt to the different ways the shifted regions come into consideration.
Smashed Sums becomes a lot easier if you mark (say by circle ), the cells that must contain a number. Use the logic like "this sum is so big, it'll require at least 6 cells in between 2 shaded cells, so whatever way I look, some cells will always be between the sum, and so can't be shaded" and mark circles for wherever shaded cells can't be. That and sums will help you progress.
I won't tell you anymore for now, since you couldn't find where to start. Sometimes its just about grasping the rules and then you might be able to solve it yourself which is obviously the best way forward, but feel free to ask if still stuck. |

Country : India | Thank you very much, this is amazing ! I will certainly try the other 6x6 too using similar logic. The hints for the shifted and smashed sums are slightly greek to me but will chew on it for a while. Thanks a lot for the prompt response. |

debmohanty
Country : India | Steps for bottom left 6X6. After usual solving, you can mark R1C5 as X, and then mark three other Xs in the grid. Then you can find two 4s in the grid. It should be easy after that. Click on "Show" below if you want to check the image.
