    nice to see a puzzle larger than 10*10! Really smooth solving path with a nice finish 🙂

    Yeah, really appreciated the solving path and the finish, but it took me more than 10 minutes.
    I don’t think my notation is adequate for Fillominos.

    I mix region and path marking, both in and around the cells, it’s totally unreadable.
    Any advice ?

    Smooth solving path, with a very nice finish with how to split the 6-mino.

    @Grizix: I also mix region and path marking, but I use different colors; path is lighter while border is darker. (A mouse has two buttons yay.) Although I should try to stick with only one to speed up the time.
