Today's genre is Tontonbeya. It's actually similar to Tetrochain in some aspects: fairly recent Nikoli genre, ported to the puzz.link editor last year, not too many puzzles overall. Genres involving triangles, circles, and squares are not so common, but they often have fun ideas that aren't really explored by more conventional types. (That said, they might be a bit annoying to annotate on paper, which might explain why they haven't caught on more widely.)
Rules: In each cell, place either a circle, triangle, or square. Within a region, all instances of a symbol that appears must form an orthogonally connected group. Each group in a region must be the same size. Additionally, each group of a certain symbol must touch exactly one other group of the same symbol across a region boundary.
(Figured I might as well add examples to these posts. Feel free to prod me if I miss any.)
Both grids are inspired by x0_000's style on Puzzle Square: symmetric givens, asymmetric regions. (At some point I might try symmetric givens and regions, but that might be way too difficult. Reminds me of the stress I had when constructing old Nanro with these restrictions.) The first puzzle might take some time to get used to if you haven't solved any Tontonbeya before, but it's overall fairly flowy and establishes many basic conventions of the genre. The second puzzle also has some flow, but is more difficult overall. It might help to understand how regions of size 8 and 9 work before diving in.
