Normal sudoku rules apply - place the numbers 1 to 9 once each in each row, column and box of the grid. Numbers placed on an arrow must sum to the number in the attached circle. Each row, column and box of the grid contains exactly one squaring cell - you must take the square of these numbers when computing the arrow sum. For example, if the number 4 was on a squaring cell, it would count as 16 for the purposes of the calculation. The numbers 1 to 9 each appear in exactly one squaring cell.
