Friday Puzzles #263

Fairly recently I had the honour of being asked to be one of Roland Voigt's weekly "experts " for his daily skyscraper puzzle project.  I am always in awe of anyone who tries to maintain any sort of daily puzzle project for any period of time, and this one is of particular note because in my opinion Roland is by far and away the world's leading authority on both solving and creating Skyscrapers puzzles.

Please take a look here:

I think eventually some commentary on my times will appear on Roland's blog - as someone who often struggles with a weekly schedule I am more than happy to be patient on this count!

Anyhow, skyscrapers this week.  Not too hard, not too easy.  Enjoy!

The Art of Puzzles: Skyscrapers

I've had a small but fun skyscrapers puzzle posted over at the peerless Grandmaster Puzzles!

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!
