The objective is to fill in each blank rectangle with an integer in a way that “balances” the puzzle mathematically.   The puzzle features three skill levels (Easy, par, and challenging) with three grid sizes: BQ Sixteen (small-grid), BQ Thirty-two (medium-grid), and BQ Sixty-four (large-grid).   Solve time can range from 5 minutes for the \"easy\" small puzzles to hours for the \"challenging\" large puzzles.
