I took 3/6 minutes for the 15/30 points. Definitely undervalued.

This was really fun. Thanks for the puzzles! The domino castle, in particular, was really cool.

And looking at the results, I typoed the arrows. Darn!

I intuitively solved the top Fillomino pretty quickly, and communicated the same to Vladimir. I suppose the intuitive ones are easier when you're solving one at a time. Also, approaching such puzzles with an open mind is probably better than approaching them expecting them to be really easy.

For the smaller one, I just figured out it'll be two 8 shapes, two 3 shapes, so the middle shape has to be 8, 2, 1. This covers all the cells, knowing that the 1 and 2 shape will be used to separate the 8s. Then it's all about whether both 3s are involved in the separation or just the bottom left one.
