It is open to us whether the following cheese is actually provably correct:↵
↵
- First attempt to fill in the cells (blind to whether they are special or not) in reading order, adding if it doesn't form a cycle.↵
↵
- Second attempt to fill in the cells, but with special cells first, in reading order, adding if it doesn't form a cycle.↵

We conjecture that one of the two always passes.↵
