It's been a while since I invented a new puzzle type, although this one is a combination of a couple of ideas already around in puzzle world.
Your task is to subdivide the grid into regions, such that every region has 180-degree rotation symmetry. (They might also have 90-degree symmetry and/or reflective symmetry, but this is not necessary).
Every square that in the solved grid is bordered by 2 or fewer lines, is denoted by the number of lines bordering it. Any square that will have 3 or 4 lines bordering it, is left blank.
The only other rule is that you can't have two single square regions next to each other, hence why the top right corner of the example must be a pair.
