This year’s 24 hour puzzle marathon is just over. Thanks to the organizers, authors and participants for a great weekend. I contributed a round again. It turned out a little less polished and balanced than last year’s, but there’s a couple of nice puzzles in there. Puzzles below, or grab a copy of the booklet.

**Dominos** (rules) The “domino extra” one turned out quite nice, the other one is more filler material.

**Geradeweg** (rules) The first one was meant to be easy, but I probably failed there. It turned out non-square with weird non-symmetry by accident. The second one is a bit more tricky, and has an antisymmetric theme.

**Checkered Fillomino** (rules) Quite happy with the hardest one of these.

**Japanese Sums** (rules) A bit of experimentation with number sets here. I’m happy with how the doubled one came out.

**Symmetric LITS** (rules) One straightforward one, and one with some interesting logic if you take the time to find it.

**Skyscrapers** (rules), **Fractional Skyscrapers** (rules) Nothing special.

**Summon** (rules) The first one was meant to be easy. The second one was meant to be trickier, but solvable. I’m not sure I can still find the full path, though, so maybe I imagined it. The third one, …

**Compass** (rules) A compass.

**Loopki** (rules) Definitely the strangest type in the set. I know the type from a portal puzzle. There’s nice logic there, but it’s quite hard to find. Well worth it, though, in my opinion. So far, I don’t know that anyone solved one of these. With preparation, they’d have been cheap points, though. The first one is as easy as the type gets, the second one is a bit more tricky.

**Scrabble** (rules) The stations of my train ride. Except for the one I managed to miss.
