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."

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.

At 2:00 PM, you can click on start ISC and then you will be given password which you will use to open that secured booklet. Then you will have exactly 2 hrs 30 min to solve sudokus and submit.
Good Luck :)
