Have a Summon. If you’ve already figured out the kind of argument this one is built around it’s not that difficult.
This is a Cave puzzle.
Here’s a Magic Labyrinth, digits 1-4.
Just survived this year’s 24h puzzle championship in Budapest! Congrats to the winners (Peter Hudak in first, edging out Nikola Zivanovic and Zoltan Horvath), and to Nils for winning the fight for best German. I expect to post (or link to) my contribution at some point, but for now here’s a Compass puzzle that I skipped in favour of two more accessible ones. Inspired by Nikolai’s survey of almost symmetric puzzles.
Next in the series of slightly deficient Masyu. Enjoy, nonetheless.
