Great puzzle! I submitted the test and got a response with the time submitted... But when I click for the results, I get:
"Results will be displayed after 02/14/2011 05:29:59 AM IST or after you complete the test (whichever is earlier)."
As Rishi mentioned, you haven't started the test. From the database, I found that you've solved and submitted the 'Example' puzzle.

You need to login and start the test to see the actual puzzles
After you complete the test, you should be able to see your score and others' too.


That's embarasing - but solving the example was also fun. I have started it. Thanks, Admin!

I dont see your name in the starters list Septen..


Thanks, Rishi. I was thrilled on having solved the example and submitting it, as the Admin pointed out.

Very nice grids, Rishi !

I completely failed the tournament . I got stuck for a very long time on a single grid, finishing it by finding a mistake, and after that I knew I would not do a good result and was a bit demotivated, so I made a few more grids but very slowly.

I returned several hours later to the grids that I had not solved, so now I can say there are top-quality grids

Hope to do better next time...

I'm not sure if I've understood the text boxes correctly. I couldn't find the information anywhere if I should enter two columns, two rows or one of each. So I decided to always enter two rows and now hope that was correct...

Edit: Not to speak of the time it took me to search for this information as I expected some arrows or other marks beside the diagram to tell me which rows/columns to enter.

Edit2: Looking at my score it was definitely meant in some other way...

Calavera, in the grid that is shown online, you will find a button "show cells to fill". Once you click that, the grid will highlight which row, column needs to be filled.

Oh well... I somehow thought this might be used to warn me about unfilled cells. At least I'll know next time :-/. Apart from that I liked the contest.

Congratulations to WaterlooMathie, Thomas Snyder(motris) and Jaku111 for taking the 1st, 2nd and 3rd positions respectively. After a long time we have seen someone Overtake Thomas for the First position. Great Show WaterlooMathie. :)

Thanks to all of you for taking time out to participate.

To add to the score sheet. Thomas had actually completed the entire sheet in 103 minutes with 17 minutes to spare!!!! But a rare typo error happened when he was transferring the digits to the text boxes. However the error got corrected with 4 minutes to spare and I think that is what cost Thomas his First position. This is just trivia.

Yes, just trivia :(. We all make mistakes from time to time. Regardless, congrats to WaterlooMathie on the victory.

I had one other comment which comes back to the entry system. It was not the reason for my mistake this time, but has gotten me on two previous sudoku tests and still does not seem to be ideal for paper solvers. In particular, I did not find the new text boxes to be any real change/improvement to the system. If anything it added more confusion to the visual applet without any new advantages. The challenge for paper solvers is still that one has to click "show cells to fill", then enter said cells, then click submit, and must do this on all puzzles. It takes longer than the entry on the puzzle tests and is more error-prone as well. I'm sure I'm not the only one to forget to hit "submit" on a puzzle they had finished (as happened on the Qixi Festival Test), or who got confused about what to enter by not realizing there is a "show cells to fill" button, as Calavera reports here, and as happened to me my first time too.

The puzzle test entry is much more friendly, and should be mirrored here. I'd recommend putting a separate tab at the top of the page labeled "paper solvers". That tab goes to an answer system exactly as on the puzzle tests, with just two boxes for each puzzle entry. There is a single submit button at the top/bottom that enters all entries when clicked and reports how many solutions have been entered and the time remaining. Having a more compressed set of answer boxes lets one constantly view the clock, and also makes it much friendlier to enter a single answer to a single puzzle. Currently, one must scroll a fair bit, and the puzzle labels don't pop out to me for some reason so much as the red text "can't see sudoku" which I always think is the variant name and not a help button. My favorite part of the puzzle system is that it tells how many solutions have been entered and the time remaining. There is no global report on the current sudoku test, and that makes me waste a minute each time before checking anything else to just see that all the submits were hit.

The one sacrifice that is necessary is to be willing to label rows and columns on the test itself. I still don't exactly understand why these need to be kept such a dear secret until halfway through the test when they tend to be very well chosen, and not having the marking on the paper makes it easier to copy the wrong row/number which seems bad too. Making a clearly demarked entry system for paper solvers and cleaning up the existing one for online solvers without the extra boxes should be to the benefit of every solver. Just my opinion, but I felt it was worth sharing since you have so often taken the time to improve things and have been getting much better.

Thanks for your inputs.

First some quick stats : We received total 800 answers in this test, out of which 300 are submitted using text box. That is a whopping 37%, considering that text boxes are introduced for the first time. This goes on to say that paper players definitely don't like the existing flash submission system, and we must do something better.

The alternate submission system, the replica of puzzle submission system, is rather easy to develop. But as you mentioned (I also noted here), we need mark the rows / columns in the pdf itself. Without marks in pdf, it is never going to be easy for paper solvers.

As more new players take part in LMI tests, it looks like they are confused with 'Show Cells to Fill' button or they simply don't know to use this feature. Several members have reported this in the forum.

Even if we don't provide the alternate submission system, we must have a single Submit button. This has been reported in forum earlier, but it is not done yet because of our technical inefficiencies.

I'm leaving it open right now for further discussion / inputs, but we'll definitely have to improve it for the next Sudoku test (26/27 March).

Indian Results Summary -
Rohan continued his good performance, standing 1st among Indians, overall 6th.
Gaurav is deservedly 2nd, while I believe he is still little rusty.
Jaipal is in good form, and looks all set for this weekend's Hyderbad's regional round.
Well done guys.

Sumit needs to do bit of catchup, but I'm sure he will.
Harmeet looks like in good form too, he mentioned that he was 'focussed' this time.
Rakesh probably decided that he will only do the high pointers ( and he achieved that, but with an overall low score)
Akash continued his trademark not doing anything in last 30 minutes :-)
Ritesh and Amit are mysteriously missing.

Is there a neat and elegant approach for solving the 150 pointer? Can someone share on the forum? I got stuck after a while...and had to resort to trial and error to complete it.
