Some time along the solve noting that 7 in box 1 can only be at R3C3 was the key for me.
The Roman on the other hand was much harder - at least it seems so from the score page so far.

Thank you! I think making this sudoku was a rarely coincidence.

Thanks to all participants and congrats to top beginners, as well to the fastest experienced solvers!

Can someone please explain how to solve Roman Sudoku.
I didn't get this part.... "Some
cells are either
partially or fully
filled, and it is part
of solving to
determine the cells
that need to be
added to."
How can you determine which of them are fully filled ??

That's part of the solve. Say you have a cell with "III". Now III can either stay III which is 3 or the only element that can be added is a V to make it VIII which is 8. So III will be either 3/8. Similarly a cell with "V" has to be 4/5/6/7/8. An "X" has to become a "IX" which is 9, a "I" can never become a 5. These things and other such limitations are used to determine where an element can be added to make the correct digit.

have some question, because when i started i claimed as a begginer, because i was. now i have trained for some time and dont now if i should still start as a beginner or maybe seasoner. It's depend of our position in LMI ratings? Or i can change it due to my own feelings who i am?

The Arrow sudoku was indeed quite tricky -- not exactly beginner stuff in my opinion.
Apart from that, on the classics I must have set a new record for the number of incorrect solves and broken puzzles. For some reason it took me 3 attempts to get each of the first two puzzles right... :( when I submitted all my answers after 12 minutes, little did I know that my final solve time would be more than twice that.
Professional musicians often claim that a catastrophic general rehearsal is the best guarantee that the concert itself will go well, so perhaps I should take comfort in playing so badly just a few weeks before the WPC...

The arrow was indeed quite nasty, especially near the end. I ended up having to use some kind of cycle strategy to eliminate a digit.

This contest probably serve as my "most typo per question" as well, having entered 25% of the puzzles incorrectly.

As far as I know, It's entirely up to you whether you want to compete as Beginner or Seasoner, depending on how you feel -- unless you have a high LMI rating, in which case you will be forced to compete as a Seasoner.

Once you have chosen to be a beginner, you can become a Seasoner in two main ways,
1. Using LMI ratings/performance on these tests/performance on Monthly tests, there are 4 criteria to get bumped up automatically.
2. If you want to make the change, you may request one of the admins to bump you up manually.

The arrow sudoku was the best. First time I am participating in such online sudokus. I could do all the other 7 online and had submitted and finished off yesterday. But today I took the Arrow sudoku on a printout and with a beautiful logic could complete successfully. Wonderful feeling... even if the timing looks awry.... Thanks once again.

The arrow Sudoku was a real test to the logic. I submitted the classics well within time and also the 3 variants again in time but the arrow sudoku was a killer. The first time i submitted i got it wrong and then it took almost 100 mins extra to solve the puzzle correctly. I really enjoyed solving it finally though I lost on the time factor. Awaiting eagerly for the next beginners contest already.

@winash26
i guess you are talking about ~~java~~ flash plugin.
I don't think anything else is required.

You can try in other browsers like chrome, mozilla or opera. Also you can try installing the browser ~~java~~ flash plugin again.

Edited by Administrator : LMI does not use java.

playee Posts: 12 Country : India	playee posted @ 2014-07-27 4:42 PM The arrow Sudoku was a real test to the logic. I submitted the classics well within time and also the 3 variants again in time but the arrow sudoku was a killer. The first time i submitted i got it wrong and then it took almost 100 mins extra to solve the puzzle correctly. I really enjoyed solving it finally though I lost on the time factor. Awaiting eagerly for the next beginners contest already.

You can try in other browsers like chrome, mozilla or opera. Also you can try installing the browser ~~java~~ flash plugin again. Edited by Administrator : LMI does not use java.
