Update - Section 2 clarification


The older version of the Instruction Booklet had Section 2 as 8~20. Please note that that has now been changed to 11~20. This is significant only in case of tied scores.

Last year the bonus points allowed upto a max of 4 wrong cells ( I guess allowing for typos) but in this year's IB I do not see anything. So is my assumption correct that if there is even 1 wrong cell, a player does not get the bonus points?

Secondly a minor technicality in the IB. In the Bonus section it is mentioned "Players submitting all Sudokus will get seven points per minute saved as bonus". I thnk it would be better if we added "Players submitting all correct answers" or something to this effect. Technically I can submit all wrong answers too. Nothing major but just an observation.

Instant Grading is enabled this year, so unless you keep submitting things wrong, you don't have to worry about that. :)

Prizes

Apart from determining the National Sudoku Champion, we have some prizes to offer the top 10, in the form of LMI Merchandise.

The top 3 participants receive a Logic Masters India mug, with their position displayed on it. Participants ranked 4th ~ 10th place will receive a Logic Masters India photo magnet.

After the ISC, the top 10 here and in IPC will be e-mailed with a request for their address in order to send the prizes. Some of the IPC winners have already sent us the details, which have been noted.

Also, participation certificates will be e-mailed to everyone, but if you want a signed hard copy of the certificate with your rank, it will be couriered to you for a fee of Rs. 99. Please mail at prasannaseshadri@logicmastersindia.com if you want to order a hard copy.

Just to clarify, this will only be for the rankings in the official results.

Clarifications about Bonus eligibility

Since Instant Grading is enabled, "Submitting all Sudokus" means submitting them correctly. Also, with the diminishing points system of IG, participants are still eligible for bonus if they score 0 points on individual Sudokus but they have to submit all Sudokus correctly even knowing it'll get them 0 points if they want to be eligible for time bonus.

Hi Prasanna,
In Inside Skyscraper Sudoku, I wonder why below line is mentioned. Just want to make sure i am not missing anything since every cell can have 4 arrows under the given rules.

"Not all possible arrows are marked."

Hi Prasanna,

"Not all possible arrows are marked."


It just means that converse rule does not apply. For example in XV sudoku all possible Xs and Vs are marked. Similarly in Consecutive sudokus all possible dots are marked.
But in Inside Skyscraper all possible arrows are NOT marked.

See R2C9 : It is valid put a left arrow, but the author didn't mark it.
See R5C1 there is no down arrow (only right arrow is marked)

A bit about the authors for the Indian Sudoku Championship -

Frédéric Stalder, from Switzerland, began to create some sudokus in 2009. Most of his sudokus can be found on his blog http://sudokuvariante.blogspot.com/. He created sudokus for various magazines, for regional, national or online tournaments, including some here on LMI. As a competitive solver, he took part in World Sudoku championships since 2011, and is since this year the best representative of his country.

Nikola Zivanovic is from Serbia. He started a blog called LOGIKA 5 years ago but is currently inactive there. Recently, he has turned his efforts towards authoring Online competitions at the International level. In addition to some contests here on LMI, including the most recent Beginners' Sudoku Contest, his puzzles can be seen on various International tournaments like the 4th Sudokucup, the WPF Sudoku GP, etc. As a competitive solver, he is a regular fixture on the Serbian team since the first World Sudoku Championship in 2006 and has secured some impressive top 10 positions in the World Sudoku Championships over the years.

Bastien Vial-Jaime is a french puzzlemaker who runs the blog EnigmAttic - http://enigm-attic.blogspot.in/, where he publishes a weekly puzzle or sudoku variant. As a player, he is a regular member of the french team at both the WSC and WPC, and has secured some impressive top 10 positions in recent years.

Zuzana Hromcová is from Slovakia, and is one of the authors at slovaksudoku.com. There is a detailed description on their authors page, but to summarize - she regularly works with talented youth of Slovakia through the Youth League on the slovaksudoku website, has co-written some contests here on LMI, and Sudokucup 5.

In addition to these International authors, there are some contributions from the LMI team as well, namely myself and Deb Mohanty. Since you're already on LMI if you're reading this, Deb's basically the person who runs the site, and has also authored many contests here, including multiple National Championships. I have my own blog, but I'm not nearly as active as I used to be. My recent efforts, apart from writing puzzles for GM Puzzles and the recent Monthly Tests on LMI, have gone into starting a Patronage system for LMI. While the Championship is free, if you enjoy our contests, and want to give something back, please check it out.

I also thank the test solvers for the contest -
Tiit Vunk from Estonia.
Vladimir Portugalov from Belarus
Frédéric Stalder and Bastien Vial-Jaime helped with testing and feedback as well in addition to contributing puzzles.

Notes about Points claims


Since this competition follows Instant Grading, we will be rejecting all points claims about typos. The IG system exists exactly for the purpose of enabling participants to fix typos. But, we will consider claims for the following cases, to remove the penalty -
1. Correct answer for Sudoku X is typed into box for Sudoku Y.
2. Answer is correct in all cells which are empty, but a cell with a given clue is typed wrong.
3. Correct answer for some row/column in a Sudoku bot not the marked Row/Column.
4. Entering 6 digits of the row/column correctly and 3 digits correctly from the row/column just next to the one marked (3/3 split for 6x6).

Please note that these are all only valid claims for removing penalty and not for awarding points. If you receive a message that your answer is wrong, you are expected to fix it and re-submit correctly to be awarded points.

Welcome to LMI!

And yes, of course. I advise you to go check the ISC page and download the Instruction booklet for all relevant instructions. Feel free to ask any queries here.

while solving online, do we need to fill in all the grids or just the marking rows for answer purpose would work.

It falls under solving techniques, not organization queries :)

But for discussion sake, you should be able to solve the IB examples as well as the competition puzzles without using meta-techniques.
