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!

  1. Enjoyable solve, but gotta recommend medium, Just sayin'.



  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.
