I almost had an aneurysm my first attempt because I thought there was a negative constraint. The rules don't state it, but not all dots are given. It's possible for consecutive digits to be adjacent or at a 2:1 ration even without a dot between them. THEN the puzzle can be solved once you know that. I hit a wall and kept restarting thinking I'd made a mistake until I realized it.

Very nice puzzle. Sum might say that is sumthing. Thanks for sharing.
