Six out of the 30 puzzles were mine; I’ve reproduced them in this post for anyone who hasn’t seen that championship. Enjoy.

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.

As you no doubt suspected, this blog is still going to continue on. If you believed otherwise, you were April fool’d by a prank I thought would fool no one. Also, I am not an elaborate alternate persona concocted by glmathgrant. Well, I don’t think so at least… if I were it would be most elaborate case of schizophrenia known to mankind. Hell, I’d be living in two different places at the same time.

Not the usual Sunday level of challenge, but still fairly tough considering every cell in the grid has a clue in it. This one is placed where it is due to being a little more quirky than my usual puzzle, as many of my Sunday puzzles are.
