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

can we have another skyscrapper from deb?

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

@Rakesh,

this is good statistic

Password protected Sudoku booklet uploaded. It has 6 pages, there is no header page, each page has 2 Sudokus.

can anybody tell how to solve the instruction booklet puzzle
PRODUCT (not got any number)
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.

Sudoku City has started - here is the link to score page - http://logicmastersindia.com/M201108S/score.asp

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?

Bad typo :-)
But no changes to interface while the test is running. Will change for the text test

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.

Its a bit of both

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.

But nice set of sudokus.

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.

Some raw statistics about NonZero scores. Not much significant change over months.
More about this after the test is over.

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

Just like to add my thanks to that of everyone else. An enjoyable end to my weekend.

Thank you Nikola -- these were fun. And I need a new printer! :)

Sudoku City is over. Thanks to all who visited the city. 128 of 199 players got non zero scores.

I'm extremely sad to announce that one of the Sudoku (Inside Skyscraper) didn't have a solution. We are still discussing how to handle the situation.

I'm sure many of you were surprised to read that Inside Skyscraper was not solvable. Left arrow was missing at R9C6. It was such a small mistake, and it almost didn't have much impact on solving the puzzle. para (Bram de Laat) was the person to notice it, and we realized the mistake 3 hours before the test end time. So we decided not to announce it.

However, we realize that some players could have been affected by the mistake, most notably para. So we decide to give full points to para, Semax, jrivet, WaterlooMathie, martin for this puzzle. Their solution is very close to what we expected. motris get 80% because we strongly believe he has a typo in the submission.

Finally, the results - LMI has a new winner this time - Yuhei Kusui who is cleanly ahead of others with 93 points / 11 puzzles. motris and skywalker take 2nd and 3rd position respectively with 10 puzzles each.

Rohan, Rakesh and Neeraj complete the Indian podium.
