Friday Puzzles #112

My fellow puzzle blogger Grant Fikes was kind enough to give me a preview of some upcoming puzzles he plans to feature on his blog, and you should definitely watch out for his entry next Monday. He also provides inspiration for this week’s puzzle, which I’m sure all my dearest readers will be pleased to see is on time again.

The idea is simple – make a 10×10 fillomino, with certain symmetric constraints. This is my first effort, which presumably is null and void for the purposes of the contest, but will hopefully act as inspiration for anyone else who might want to have a go. Upon re-solving this, it’s slightly less easy than I thought it was, which makes me think it’s a bit of shame I can’t enter this, but then I suppose I shall have to come up with something better than this. Anyhow, bearing in mind I haven’t made many fillomino (4? 5?), I’m going to be a bit cagey and call this a medium. Enjoy!

EDIT: What I initially had in mind was probably medium, but as Jack points out below what I initially had in mind had two solutions. Anyhow, this unique version gets cranked up to hard!
