Sudoku Zero has many names: Sum Sudoku, Additive Sudoku, Kakuro, and so on, but the rules are equally simple in all games.

--  Note the cage: groups of cells shown as dotted lines.
--  Make sure that the sum of the numbers in each cage is equal to the number in the upper left corner of that cage.
--  The special rule for this number logic puzzle is that the sum of all the numbers in each 3x3 box, in each row or column, is equal to 45.
--  The numbers in the cage, each row, each column, or each 3x3 box cannot be repeated.
