It's my first Strange-Shaped Sunday of many to come! I couldn't make up my mind whether to use non-square cells or an irregular grid shape, so here we are. I'm a big fan of Symmetry Area, or Fillomino (Symmetry), and switching to a different grid does some interesting things for this genre.

If you want to warm up with some regular Symmetry Area, Freddie covered the genre on GAPP a little over a year ago: Archive: Monday, 16 May 2022

Rules: Divide the grid into regions of connected cells. All regions must have 120° or 180° rotational symmetry about their centre. Two regions of the same size may not share an edge. Clued cells must belong to a region containing the indicated number of cells.

Note that in addition to the 180° symmetry that's familiar from square grids, shapes can also have 120° symmetry on hexagonal grids, such as the 4-region at the bottom of the example puzzle.
