Monday Mutant 95: Polyominous (no rectangles)

In this Polyominous puzzle, no region may be shaped like a rectangle. The rules are otherwise unchanged.
The latest issue (74) of Akil Oyunlari contains four Akari puzzles and two Cross the Streams puzzles constructed by me! These puzzles were constructed for the magazine, and won't appear on this blog, so buy the magazine to see 'em!

I liked this variation. The new rule actually means a couple of numbers will be excluded, which opens up logic like that used in the upper left and at the end of the puzzle. Lovely.

I'm impressed, excellent puzzle. And fun, too!

Great puzzle. Who knew that if you eliminate rectangles, you kill the 1's the 2's and many 3's, and that the constraint generates some great invisible paths out of the smallest nook or cranny. Thanks.

My first reaction was simply amusement at the concept: Fillomino for people who really hate Shikaku. But as others have pointed out, the rules aren't just a cute concept, they create very interesting logic that is unique to the variation. As soon as I filled in the early unclued 7 I knew things were getting interesting.

Great concept, and a fun puzzle! I suspect there are further tricks one can wring out of this variation.

I'm agreeing with the people above, a very clever variant leading to interesting deductions.
