Puzzle #34: Masyu

This Masyu is difficult for a 8×8, I think. I’ve had lots of time to make puzzles recently.



Puzzle #31: Masyu

This Masyu is stolen from my AoPS blog, so the format looks somewhat different (bigger circles, no border). Posted to showcase a technique.


Puzzle #26: Slitherlink

I mentioned I would return to other puzzle types, right? This is a Slitherlink, intended partially as a hint to that last Masyu. It can be understood with a trick that is also used in Puzzle #25. This Slitherlink making thing hasn’t been perfected, hence the uncentered numbers.

Also, I may or may not be able to post much longer, depending on whether I can continue using the Affinity beta after the full version releases.Slitherlink.8.6.1

Puzzle #25: Masyu

Puzzle #25 on the 25th? Clearly it should be a 25×25. This puzzle was inspired by a 15×15 I investigated/discovered/created a long while back for a yet-to-be-finished iOS app. Except this is harder. Using a math competition analogy, if the last couple puzzles were ‘AMC’-like, and the harder puzzles here are ‘AIME’ level, this is an Olympiad puzzle. Meant to be investigated, possibly with a dose of if-then, but once the theme is understood it should be doable? That’s the hope, anyway. (The hope is also that I’m right about this being hard. :P) On an unrelated note, I put as much time into this puzzle as I did into all other September puzzles combined. After this, I hope to return to other puzzle types besides Masyu. 25.25.1
