I hit an interesting problem with my puzzle game Logic Islands - 3 out of 6 rulesets would hang forever trying to generate maps larger than 7x7.

The trick that worked? Using Wave Function Collapse, but choosing what to generate based on each ruleset - islands for some, walls for others. This flexibility made complex constraints (like "no 2x2 blocks") trivial to express as tile connection rules.

My favorite result: the "Minimal" ruleset enforces "all wall regions must be exactly 3 cells" using just 11 tiles and local WFC constraints. No post-processing needed.

Now generates 12x12 maps instantly instead of hanging forever.

Anyone else using WFC for logic puzzles beyond typical texture synthesis?

I wonder how well it will work for generating certain street tile patterns, where tiles of different sizes are used and where it is not allowed to have four tiles meeting at one point and where there are no H-patterns. See [1] for a large pattern and [2] for an animation using patterns within an 8 by 8 square. I did figure out a set of Wang tiles [3].

Nice to meet you. It seems that you have been researching this topic in depth. Since you have been researching this topic for a long time, I don't have any immediate thoughts on it, but I think I need to think about it a little more.

While working on Simple-Tiled WFC this time, I kept wondering whether I should reference neighbours in more than four directions, but in the end, I'm glad I finished without referencing them. I hope this Random Street Tile Pattern can also be solved in such an elegant way!

I was just wondering this for myself, not something for you to figure out.
