Region - The 3 x 3 squares within the grid
Clues - The numbers that are written in the grid
Potential Numbers- All of the numbers not in the line
Candidates - Those potential numbers that are not in conflict in the

The two-dimensional Sudoku puzzle is played in a grid of 81 spaces.
Anywhere from 20 – 40 clues of numbers are written in while the remaining
spaces are blank. The player must fill in the blank spaces by deductive
reasoning. In Kakuro, there is no set number of spaces in the Grid. There is
only ONE correct solution to each Sudoku and Kakuro puzzle.
