I had a look around at some of the other Sudoku helpers, and noticed that none of them automatically tracked all the data while you are solving a puzzle.
This one tracks the possibilities that each location can have.
(I apologize to those who have small screens... The GUI width and height is about 700+ pixels)
Click on the small buttons and see what happens!
I don't really know how to explain how to use this, try learning through experimentation!
