The puzzle below is much like a 6x6 sudoku: the numbers 1 through 6 must be placed across each row such that each number appears only once in each column. The catch is that the grid is divided into regions, and your only clues are the sum and/or product for each region.
Example: “18×” for a region with three cells would mean that the numbers for that region have a product that equals 18. They could be 1, 3, & 6. Or 3, 3, & 2 (NOTE: It IS possible for the same number to appear twice in a region, as long as they don’t share the same row or column.)
