#133: Logic Masters '24 Qualification Round
6 April 2024
I co-authored the qualification round for this year’s Logic Masters (the German puzzle championship), together with Thomas Fink (whom you might know as Phistomefel). This post contains all of my puzzles from the round, plus three bonus puzzles.
#132: UKPA Open '24 — Snakes & Hydras
28 February 2024
Here’s my first contribution to 2024’s competitive puzzle calendar. I wrote a round for the UKPA Open Puzzle Tournament which happened last weekend. The round concept was based on a puzzle I made for last year’s EnigMarch.
#131: Hinge
4 February 2024
I don’t post a lot of vanilla puzzles in existing genres here (those often end up on Puzzle Square), but I’m particularly fond of this construction.
#130: New Genre — Bramble
7 January 2024
I’ve created a new genre and would you believe it, it doesn’t involve drawing loops or even paths. This post introduces the genre with a small example puzzle and three larger puzzles of increasing difficulty.
#129: Foggy Twilight Kurotto
27 November 2023
After making the Twilight Kurotto for Black-out Friday, I figured these rules would also make for an interesting fog-of-war puzzle. You’ll have to solve this one in Penpa.
#128: Twilight Kurotto for Black-Out Friday
24 November 2023
The Griddle has organised another pack of shading puzzles for Black(-Out) Friday. Last year, I made a Twilight Cave, so this year I wanted to explore a Twilight variant for a different genre. Check out the full PDF over on The Griddle, with many more excellent shading puzzles.
#127: Hexagonal Compass
21 November 2023
I’m a little surprised that I haven’t seen Compass done on a hex grid before.
#126: Rail Pool / Masyu
6 November 2023
This was originally going to be a co-op puzzle for two solvers. But after I had finished the puzzle, I realised that it would work much better as a hybrid puzzle for a single solver.
#125: S-Policy — "I of the Cyclops"
3 November 2023
Unsurprisingly, I’m not the first to come up with this theme but I’m very happy with how clean both theme and solve path turned out. The “X” is… uh… a specular reflection off the eyeball. Or dirt.
#124: Chocolate Pentominana
30 October 2023
I had the idea for this Choco Banana variant a couple of months ago, but only just got around to trying it out. The rules are probably a bit too strong and could maybe do without the diagonal adjacency part, but sometimes it’s fun to solve a puzzle that mostly flows from a genre’s “passive” rules instead of clues.
