Friday Puzzles #159

So it's a bit of a first this week, dearest reader, as we depart from a nikoli staple and instead try something different.

The idea of skyscrapers is this.  Fill in the grid so that each number from 1-N appears exactly once in each row and column, latin square style.  Each digit represents the height of a building, with bigger buildings blocking smaller buildings.  The clues on the outside of the grid tell you exactly how many different buildings are visible from that direction - so for example a row containing 123456 has 6 buildings visible from the left, and 1 from the right.

This was going to appear in the next version of the UKPA beginners contests.  By the way, if you haven't had a go at this month's contest, why not!?  Registration is quick, easy and free!  Anyhow, this puzzle was probably a little much for one of those, but I'm sure it'll be appreciated here.  I'll stick a hard label on this seeing as it is the first one, just to be safe.  Enjoy!

  2. Yeah, that's probably fair enough. I'd never made skyscrapers before until recently, and I wasn't convinced they were really tough - but it's easy for me to say that as the author, and some of the test times begged to differ. Like I say, it's the first one on the blog so I think I can get away with hard just this once.
