Rules of MASYU, for those unfamiliar: https://www.gmpuzzles.com/blog/masyu-rules-and-info/
Hey guys! So I just discovered this really cool puzzling site called the Puzzling Stack Exchange (puzzling.stackexchange.com), and it's really cool! Users create cool new puzzles to challenge each other. I really want to contribute to this site with a bold new puzzle. But I can't come up with any new ideas!
Here's the best plan I got so far: Since I really like MASYU, I'm thinking of creating a MASYU puzzle for PSE. But just an ordinary MASYU puzzle would be boring. For a site like PSE, I need it to be really special somehow! Specifically, I want this MASYU puzzle to be free-floating.
What's a free-floating MASYU?
A free-floating MASYU puzzle is a MASYU puzzle that has no edges.
Many MASYU puzzles require deductions using the edge of the board in the solution. I want a MASYU puzzle that, in a sense, takes place on an endless board, and is just "floating" in the middle, with no edges for its solution to grapple on to.
As an example, here's a possible attempt at creating a free-floating MASYU:
However, this isn't a valid MASYU because more than one solution can be found:
Your task is to create a free-floating MASYU puzzle with a unique solution... or prove that no such puzzle exists.
