Strict inequality… So that means the inequality signs also act as (some) borders?

Yes, that is correct.

Apparently “preview” is not equal to “practice”. I get enough preview puzzles, but don’t get enough practice puzzles. xD
Anyway, nice tricks, but is there any other trick only found in Greater-Than Fillomino?

Hard to say when I don’t know all of the tricks you’re talking about, but the answer is probably still yes regardless (i.e. there are plenty more).
mathgrant has posted some of these before (I think his first Monday Mutant was this type), so you might find some other cleverness there.
I’ll confess I don’t know what you mean when you say preview != practice…

In my opinion, “preview” is only one puzzle, just to show how things work. “Practice” is multiple puzzles, to learn the tricks and prepare for the test.

That is correct.

Honestly, I was surprised that an interesting puzzle was possible using these rules and no givens. IMNSHO, though, your specimen from this preview series is far more visually appealing.

Nice one. So how do these preview puzzle compare to the contest ones in terms of difficulty level?
June 1, 2011 at 3:08 pm |
Because of our usual construction tendencies, I think it ended up that in general mathgrant’s puzzles are a little closer to the easy level of the type in question, and mine are closer to the harder level. Exceptions may exist of course.

Indeed. I think I can safely say, without spoiling anything, that there was at least one time when I was surprised by how difficult of a puzzle my co-author was able to construct compared to mine. *laughs*

Amazing! I think Greater-Than most beautiful than Shape F. I solved both of them, but i think i liked very much G.-T. F. because of left-right upper side construction. Thank you very much!
