This was another of my entries to the most recent Logic Showcase. Halfway through constructing the other entry, I wondered whether there should be a restriction on how many snakes can visit a region. I ultimately decided to call this a variant because it doesn’t feel integral to the ruleset, but it results in a bunch of interesting logic that seems worth exploring.
This was one of my entries to Logic Showcase #46 on Puzzlers Club, “It’s supposed to be touching Dynasty”. The prompt was to take a dynasty genre and replace the “shaded cells can’t be adjacent” rule with something else. I actually submitted four puzzles with different rulesets this time, and I’m putting the two better ones on the blog. They were tied for third place.
The Cracking the Cryptic Discord server has started running some guest series of puzzles. There was a Slitherlink variant series over the last month to which I contributed this puzzle. Similar to Twopa or my previous Rail Tool, you need to find a pair of solutions such that each clue is satisfied differently in both solutions.
I continue my exploration of [Wall]-Like Loop genres. I’m quite fond of the logic in this one. In particular, allowing unused cells outside of the loop but not inside leads to some interesting deductions I haven’t seen elsewhere.
This is the second puzzle from my Logic Masters qualification practice that I wanted to share-and-my favourite from the entire set. Turn-and-Run is a really interesting directed loop genre that I’d love to see more of.
A month or two ago, I made a whole bunch of practice puzzles to prepare for the qualification round for this year’s Logic Masters. The puzzles were all a bit rushed, because I had to get through almost 30 genres in a couple of weeks, but there were two constructions I was particularly happy with that I’ve been meaning to put up on the blog.
Here’s a semi-original genre. (Yes, it’s a loop genre, of course it is.) I was originally exploring this ruleset as “Canal-View-Like Loop” which is also something a few other people have looked into in the past. But (a) that’s a mouthful, (b) I thought these rules are nice enough to deserve their own name, and (c) “Grandstands” is just such a perfect fit.
It has been brought to my attention that I have made the only Touch Slitherlink in the database right now. Here’s another to keep the first one company.
This month is EnigMarch, the puzzle equivalent of Inktober or NaNoWriMo. Each day has a one-word prompt and people can make any kind of puzzle they like. I’ve been using the opportunity to experiment with instructionless puzzles, something I haven’t done before.
This was my entry to Logic Showcase #42 on Puzzlers Club, “That’s a Wrap!”. The prompt was to make puzzles on grids whose edges wrap around in some way. This puzzle ended up netting my third win, though only by tie breaker.
