No, it wasn't broken.
How many different possible solutions are there for filling in a Sudoku
if no spaces are filled in? Now fill in 6 of the spaces. How many
unique solutions result in numbers in those pre-filled conditions?
Logically, it *has* to be possible to come up with multiple solutions,
otherwise there would only be *one* way to fill in the boxes to start
with.
