Note: I've added two more givens. The puzzle was solvable, but there were certainly a couple of steps that were not realistically discoverable. (The recursive puzzle checkers show that there is only one unique solution to this grid without ANY given digits, but it's fundamentally unsolvable without extensive bifurcation. My challenge was to decide what given digits to include to set an appropriate level of difficulty!)

Enjoy the puzzle and please let me know how you like it!
