(See 294 for info about this “reject” series.) The adult in the earliest versions. One of the worst offenders in terms of overdoing the level of challenge.

The visual theme in this one is pretty obfuscated and probably nontrivial to catch. Your hint is that it’s staring at you from the start.

(See 294 for info about this “reject” series.) This one would have been the adult. I really liked this puzzle, so it was a bit of a shame to have to cut it.

(See 294 for info about this “reject” series.) Now for the type cut from the Mutant section. When it came time to decide what to take out, it was pretty clear that I may as well avoid having two Slitherlink variations in the mutant section, and there was no way in hell I was taking out Liar Slitherlink.

This puzzle was the baby on an early draft. Later drafts had a tweak with a lot more clues and an almost identical solution, but ignoring the difficulty difference I find this version superior. A bit heavy for Monday, admittedly.

Melon’s Puzzle Zoo has ended

Around the time of this posting, LMI is no longer accepting score submissions for the contest. Below is a link to the puzzle booklet, the same as the one on LMI without the password. There is also a PDF that has all of the puzzles on the test together with their solutions (don’t open if you don’t want to see them yet!), as well as some brief comments from myself about the puzzles. Mostly I pointed out the tricky innovative logic the puzzle had, if any — and for the adults there almost always was some.

I think all of the puzzles this week ended up being easier than you’re used to from here. My apologies if that’s not your cup of tea.

The idea in this puzzle is something I tried for a long time to get in standard Slitherlink without too much success. Then I realized I could combine it with another trick in this variation.

Newest factoid deduced from WordPress statistics page: if you search for “puzzle N” on google where N is a sufficiently high number, there’s a good chance the appropriate puzzle on my blog will be among the top results. Weird.

Puzzle 269 (Slitherlink) [Interior Path]

January 7, 2011

This is a Slitherlink puzzle, with a twist. The clues have their usual meaning and there is still a single loop to draw. But after drawing this loop, you must also be able to draw a path passing through adjacent grid squares that visits every square inside the loop exactly once. The path starts and ends at a different square, and although it may not be uniquely determined, one must exist.

I doubt I’m the only one that believed this variation was begging to be revisited. Last time I posted it, I gave clues in one third of the grid cells and had the nerve to call it a sparse arrangement. To be fair though, this particular instance does things a bit differently from that last one.

Puzzle 265 (Corral/Slitherlink)

October 29, 2010

This is a Slitherlink and Corral hybrid puzzle. As usual for both types, draw a single loop along the grid lines that does not intersect itself. Each clue in the puzzle can function as a Slitherlink clue or a Corral clue (or both), and it is up to you to decide which one. If it is a Corral clue, it must appear inside the loop. (There is no such restriction for Slitherlink clues.)

Puzzle 263 (Slitherlink) [Dominoes]

October 21, 2010

This is a Slitherlink puzzle, with a twist. 20 of the clues in this puzzle have been taken out of the grid as a set of 10 dominoes (listed below the image). The original positions of these clues are marked as shaded squares. Find out where each domino goes and solve the resulting Slitherlink puzzle. Each type of domino is used exactly once. The exact positions of each domino may not be uniquely determined, but the clue number in each space will be.

Domino list: 00, 01, 02, 03, 11, 12, 13, 22, 23, 33

Slitherlink is amazing. It’s so easy to come up with all kinds of wacky variations that work. I don’t think any other type is as accommodating.
