Puzzle 49: Smullyanic Dynasty

[zotmeister]

See Puzzle 4 for instructions. This one took me less than five minutes to make the graphic for, and over two hours to test solve and repair! It originally lacked the center given, which I put there when I realized the original solution was not unique. Thankfully, that didn't sequence-break the puzzle at all.

One peculiar "feature" of this puzzle is that it has a particular weakness to metalogic, the use of which I of course discourage, but I must admit that this puzzle makes for an interesting study because of it. I challenge you to NOT use advance knowledge of a unique solution (metalogic) as a solving aid; once you've solved the puzzle, try to find the metalogic shortcut (if you hadn't already). - ZM
