this ruleset is so constrained that you need only about 3 givens to make it work. that is a "miracle" sudoku, and it's not very hard.
THIS one, with SO MANY givens, still looks extremely hard. perhaps that is a different kind of miracle.
p.s. even if you start with 6 or 8, there's still a 50/50 symmetry, and the disambiguation is FAR away.
