It’s been awhile, hasn’t it? Obviously this omits the wackiness of Heyawacky and is a typical nikoli Heyawake. Well, maybe typical is too strong of a word.

The main issue with this puzzle is that it is absurdly susceptible to meta-logic, so I’m just going to have to remind you that you’ll miss the full solving experience if you use any.

If you’re a real master of Heyawake, try solving this without marking the squares where black cells can’t go on your first run.

Puzzle 200 (Nikoli Octathlon) [Unique]

February 21, 2010

Before I get to the rules and the puzzle itself, I’d like to say this first. I understand this puzzle is not for everyone, with some very complex rules and an absolutely enormous level of challenge. But if you’ve come here to enjoy puzzles, you would be missing out by avoiding this one. The solution to this puzzle is a sequence of pure logic, probably with more variety than almost any other grid-based logic puzzle there is, involving virtually no thinking ahead at all. I believe that anyone who perseveres to the end of this puzzle will feel very well rewarded for their efforts. Best of luck.

Puzzle 178 (Akari EX)

This is a Sunday Akari EX puzzle.

According to the about page, “sundays will be anything from hard to ridiculous; the only limit is that there is a logical solution with minimal thinking ahead.” Well, this one has a logical solution… but it takes the word ridiculous and goes to the sun with it, maybe to the point of being unreasonably hard. Puzzle 100, the 100 by 100 Akari, is a cakewalk in comparison.

Best of luck to anyone brave enough to tackle this one. And don’t worry, there won’t be another puzzle at this level for a long time, if ever.

A variation that is back by popular demand. Speaking of which, if there’s any other puzzle types you want to see more of, commenting positively on existing puzzles of that type is a good way of letting me know.
