Rules of 'Equal Product Sudoku'
Place numbers in the grid such that each row, column and 3x3 box contain the numbers 1 to 9. The given crosses mark groups of four cells in which two pairs of diagonally opposite numbers multiply to the same product.
This variation is on the same lines as the Equal Sum Sudoku.
