just as suggestion
is it possible that after the test a pdf containing solution would be uploaded so that after the test is over for those who didnt got all the puzzles can check it out.
solution can by only solved grids or with few steps whichever is convenience..
plz reply...

It is not always possible.
After creating the puzzles (and examples), authors spend lot of time writing the IB and PB. We can't ask them to write the solution booklet. It takes time.

It is much easier if you ask for solution of specific grids. Even if you ask 1 month after the test is over, I'm sure you'll get the solution posted in forum.

Attention top players : Change in Bonus points structure

We are making a change in the bonus points structure for this test.
Players solving all 12 puzzles correctly will get "1 point per minute saved" as bonus point.
Players solving 11 puzzles correctly (and 1 incorrectly) will get "1 point per 2 minutes saved" as bonus point.

We'll introduce "Claim Bonus" feature in this test.

You can click on "Claim Bonus" after ALL sudokus are submitted (either using online or paper mode).
Submissions will not be allowed after you "Claim Bonus"

Time bonus as discussed above will be computed from the time this button is clicked.

any links where we can find variations of skyscrappers ?

Roland Voigt's site - http://www.hochhausigel.de/e-varianten.html - lists lots of Skyscraper variations, many of them being original to that site.

Here is a "First 3" Skyscraper (though it solves like a different type of Sudoku)

Enjoy!

Nice grid, despite the fact you didn't achieve to have 2 visible skyscrapers from bottom of column 3

ODD/EVEN ( just placed DIgit "6" in all the rows)
plz reply..

PRODUCT:
Opening: 720 in Row 1 = 1x2x3x4x5x6 or 2x3x4x5x6; 120 in Column 1 is 1x4x5x6 or 4x5x6. So R1C1 is 1. With that it shouldn't be too hard.

ODD/EVEN: After the 6's. The 5 in C2 can't be in R3 or R5 as that would force the clue in that row to 3 and it has to be even. So it has to go into R2C2, which also gives you the 5 in R1. Then check out R4 for where the 5 goes. It shouldn't be too hard from here on. Look at the 4s first when you've placed all 5s.

possible typo. The test page says "Consider my score for the LMI puzzle rating". Sholdn't say "for the LMI SUDOKU rating"? is this a sudoku contest or a puzzle contest?

A better version would be
"Consider my score for the LMI ratings"
This would not require frequent changes. Can be implemented after this test is over.

Thanks for a very fun test Nikola. I wish I didn't have to travel this weekend (forcing me to wake up at 4:30 AM to compete), but I'm glad I got the chance to see this beautiful, beautiful city to start my journey.

Enjoyable test indeed. Thanks for adding to my weekend.

p.s. What is up with the ever increasing number of folks who are registered and who sign in to take the test and then submit no results? My jaded American mindset is that there may be many folks registering under one name to get the test, solve it, and then return under another name to solve well later. Anything that can be done with additional technology to prevent this, or are we all just on the honor system here? Sorry to drop a mess on the table here, but the fact that so many signed up and didnt enter is disturbing - and its only been increasing.

Many other possible reasons to this. Some of these players can simply not have a printer - they get the puzzles, and they will print them or copy them by hand later. Some may not have enough free time to participate; so, again, they get the files now and solve later.
There are also some players who do not want the others to know their score - many consider that they are not skilled enough and are afraid of being ridiculous, while some are skilled and that's the reason why they do not want other top players to know about their strengths and weaknesses. I know such players.
Finally, some are just not interested at speed solving, so they see no interest in sending back answers within a time limit.

It is also my case. I get used to start the test and not submit my answers. I really hate rewriting the solved columns/rows, because always make some stupid typos and such mistakes. For me it is not important to be in the results table. I omit the last 5 minutes (the time of possible submiting) and that is how I can still compare my participation with the other contestants
