Pretty tricky! At the start, I thought the "exactly one" constraint would make it harder (can't eliminate 1/6 from squares that see 2 others), but after some coloring, it turned out to be very helpful!

Very nicely constructed. Easy but intuitive.

Loving this constraint. This is my favorite of the series so far. Very fun, thanks!

@GameWorksRP: I was thinking the same thing, but then I read the rule about "exactly one", and looked at r6c6.

I completed the puzzle and am fairly certain there are multiple solutions. You can switch out the 3/4 pairs for 5/6 pairs and none of the rules are broken.
Rail Man: Thanks for solving the puzzle. Swapping 3/4 and 5/6 is not possible as it breaks the Knights constraint - but only in one place so it is easy to miss.
