Normal sudoku rules apply.
Each of the numbers in a quadruple constraint must appear in its four surrounding cells.
Numbers must not repeat in a cage. All cages of the same cell size will sum to the same value. (Example: all 3-cell cages will sum to 6, all 4-cell cages will sum to 10...)
The sum of each cage size is to be determined by the solver.
