Quantum Sudoku

Quantum Sudoku offers a new and enjoyable way to solve traditional Sudoku Puzzles.
Just find all the "Entangled Pairs" and the entire solution will unfold.
What's an Entangled Pair?
Two empty cells that have a mutually exclusive property.
How to find them?
Easy. Just pick any number, say #7.
Then check each block: How many possible hiding places are there for my #7 in this block?
If there are exactly two possible hiding places, then you found an Entangled Pair! Swipe across those cells to claim it.
