Sudoku Zero has many names: Sum Sudoku, Additive Sudoku, Kakuro, and so on, but the rules are equally simple in all games. Like the classic Sudoku, your goal is to fill in the nine squares with numbers and make sure that the sum of the numbers in the cage (the area separated by dotted lines) is equal to the number in the upper left corner of the cage. Still feel complicated? Lets review the detailed rules below.
-- As in Classic Sudoku, fill in the numbers 1-9 in all rows, columns and 3x3 box
-- 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.
