Puzzle 306 (Heyawacky) [Pentomino]

April 1, 2011

This is a Heyawacky puzzle, with a twist. Partition the grid into the twelve different pentominoes so that every pentomino contains exactly one symbol (number or question mark). Then take the pentominoes as the rooms and solve the Heyawacky puzzle. A number in a pentomino gives the amount of black squares inside. A question mark represents a number not given – you must deduce how many black squares are in that room.

Not really an April Fool’s day puzzle, but maybe it counts that this is far harder than the size suggests. Actually it’s currently the smallest puzzle on the blog in total area, excluding examples.

Perhaps a bit heavier on the if-then logic than what I usually post, but pentomino puzzles tend to be like that. If you use both sets of constraints together well, you can avoid a lot of it.

(See 294 for info about this “reject” series.) The adult of old versions, yet again. Those of you who finished the actual test back in February may not find this one as uberhard as it is. The difficult, themed logic in this puzzle ended up being transplanted to the (non-hybrid) Out of Sight adult during a phase of replacing puzzles, and that adult survived to be on the real test. So those of you who found what that themed step was won’t be as surprised on this one.

That’s the majority of the rejects I plan to post. There are a few Friday-level puzzles left, particularly some of the old Hybrid adults. I’ll post them in the near future as I really liked all of them, even if they were too hard, but I don’t know exactly when. For the most part, we’re back to original material now.

(See 294 for info about this “reject” series.) You’ve probably got the pattern now, but this was the adult in the most recent versions that still had this type. I was a little sad to cut this one (as has been the case for every Wednesday…), but at the same time finding the main break-in seemed too hard relative to the rest of the puzzle. I spent a very long time trying to tweak this one to alleviate that and do the themed step better justice, but didn’t have much luck.

(See 294 for info about this “reject” series.) The hybrid type that didn’t make it on. The issue with this type is that I had already reduced the hybrid section to just having adults, and all of the types except this one had one nice fit for the difficulty level I wanted. But here the baby (the puzzle above) was a bit too easy and the adult a bit too hard. As it was I already liked the other hybrid types better, so it wasn’t a great loss.

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.
