    This is one puzzle type where Paint is _not_ your friend…

    • Jack Bross says:

      I always do these in MS Paint, and Thomas takes the time to make the dotted lines secretly solid for flood fill purposes. Worked fine for me …

      • Andrew Brecher says:

        Maybe I just need some advice on notation. How do you use flood-fill on a fillomino: just to mark completed -ominos, or do you color-code them based on the numbers? I’m already using two separate pen colors (one to mark connections within an -omino, one to mark known borders); I can’t imagine adding even more colors without some keyboard shortcuts or macros.

        • Jack Bross says:

          I’m just filling in colors (shading the whole square) based on the numbers. There was somebody else who described this and it turned out they used almost exactly the same colors as me, which is interesting. Anyway, I just color 1 squares red, 2’s yellow, 3’s orange, 4’s purple etc. It’s not super fast since you can’t just left/right click and have to grab the color you want, so I’d use pencil and paper for a speed situation. If I have an indeterminate sized polyomino forming, I’ll just pick some neutral color temporarily.

        • Neelix says:

          I use the same, 2 pen colours, one to mark internal connections, one to mark the borders. I solve in GIMP using the pencil tool, after aligning the puzzle to an invisible grid.

    We have no idea how to solve this… Sounds very hard! Good luck to all who try it seriously 🙂

    • Neelix says:

      If there were any luck involved I’d probably lose interest. Luckily for me it’s logic all the way. 😉
