There cannot be a domino equal to the minimum or maximum, unless it also is marked with a cage.

Took a couple of read-throughs to really understand what the negative constraint meant. Really cool variant! Always fun to discover new ways to narrow down options.

I didn't see the negative constraint rule and stuck for about half an hour looking and not understanding how to do it. With the negative constraint it is a very lovely puzzle thank you!!
