Symmetry area is a variant of Fillomino. The 2nd puzzle was for training for I believe a Puzzle GP. I haven't tried much on setting this genre, but it's a good fillomino add-on. Here are the rules :
Divide the grid into regions.
- A number indicates the size of the region, in cells. Regions can have any amount of identical numbers, or none at all.
- Two regions of the same size cannot be orthogonally adjacent.
- Every region must have 180° rotational symmetry around its center.
