  1. Solved all four Utopias!

    This is a very original and fascinating type. It combines Fillomino-like region division, Nurikabe and Tapa-like wall connectedness, and object placement logic really well. All four puzzles were a delight to solve.

    I like how each puzzle is constructed around a clear, focused central idea, and all puzzles feel very different from each other.

    Puzzle 39 is an excellent introduction to the type with a global break-in followed by a lot of local fiddling. Puzzle 41 changes style and pacing very abruptly about mid-way, to the point where it feels like two separate puzzles fused into one (possibly a favourite). Puzzle 43 has a large open space miraculously resolved by a small congregation of clues in one corner. And Puzzle 56 has a prageny oernx-va urnil ba gur bowrpg cynprzrag, jvgu ertvbaf ernpuvat nebhaq gur pragre gb pbzcyrgr gur fbyir.

    More puzzles of this type would be greatly appreciated. Given that it is new, you are probably still exploring, but have you thought about larger puzzles?

    (One more thing. Is there any significance to the type name?)


  2. Thank you very much!

    I do have a few more puzzles of this type to post, and I’ll definitely think about creating some larger ones. This is actually a fairly difficult type to construct, because there’s a maximum number of clues that can be placed, and the more clues there are the more restricted the solution is.

    There’s no real significance behind the name. I just liked it, and it felt vaguely appropriate.


    • I just went back to try this one. It’s one of the first ones I created, and it turns out that I made the opening a lot more difficult than I intended (The 11 in the center was a 9 before I needed to increase it for the solution). There is still a logical path that can be found (I need to be able to prove uniqueness), but overall I would consider Utopia to be more of an intuitive type.
