Balance Quest is a new mathematical puzzle containing a large grid comprised of grey and white cells - some are pre-filled with numbers,
others are empty. Your task is to fill every empty cell with a positive or negative integer in such a way so that each white cell's
value equals the sum of its adjoining half-height cells. When complete,the Balance Quest puzzle grid will "balance" itself in
such a way so that the four center cells surrouding the center "zero cell" will always add up to zero. The puzzle has one,
and only one, unique solution.
There are four rules that must be followed in every Balance Quest puzzle:
(1) The grey cells (the two outside columns) must include all integers between -16 and 16, except zero.
(2) No number can be repeated within any of the grey cells.
(3) No number can be repeated within any of the white cells.
(4) The number in each white cell must equal the sum of its adjoining half-height cells.
Note: The center "zero cell" is always the sum of all
four of its adjacent cells.
All other numbers are equal to the sum of its
two adjacent cells.
