Melon’s Puzzle Zoo has ended

February 28, 2011

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.

This isn’t quite 178, but it has some tricky steps in the same spirit as that one. Probably tougher than a usual Saturday.

I thought this one ended up extremely elegant. The size is just barely large enough for all the logic to work and virtually no piece of information is wasted. Those of you who made it all the way through Puzzle 100, the really large Akari, may have some deja vu in this puzzle. I find this appropriate since Puzzle 200 is coming up so shortly.
