Florian

Most of you have probably hear the sad news: Florian Kirch passed away last week. I can’t claim to have known him well; a little better after preparing for and competing at the WPC this year with him. That was a great experience, I’m glad I had the opportunity. The whole thing is quite a shock, more so since he seemed full of plans: He’s behind the first German youth sudoku championship that is being held this year, and was actively working towards a WPC hosted in Germany, besides a variety of activities in other fields.

If you’d like to solve some of the puzzles he constructed, I’ve collected what I was able to find. I’d be happy to extend the list. The 2015 Logic Masters certainly stands out, my favourite of his rounds there being “Vorsicht klebrig”, a set of Tapa, Fillomino and Slitherlink puzzles that had to be matched to normal, cylindrical and Klein bottle topologies.

I’ll close by reposting a puzzle dedicated to Florian’s memory that I first published here on the portal.

Rules Glue the grid to form a Klein bottle, by identifying one pair of opposing edges directly, the other pair after flipping. Then solve as an ordinary Tapa.

    Thanks Rob,
    I’d also gone hunting for Florian’s puzzles (with less success), I’d already solved his Portal ones.
    I enjoyed talking and playing card games with him at WPCs, he will be missed.
