Yes, I hope that Sudoku City will serve as some practice for Skyscrapers contest at LMD

It is interesting why Nikola named this set as "Sudoku City", and not "Skyscraper Sudokus"

A 9*9 sudoku contains 81 skyscrapers. There will be 12 9*9 grids on this contest, so it makes 972 skyscrapers... This is undoubtedly a beautiful little city

You can find some "inside skyscrapers" (or hidden skyscrapers") here: http://stigant.livejournal.com/tag/hidden%20skyscraper%20sudoku

Here is my contribution (not easy grid):

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.

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

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.
