MaffDoku adds a mathematical twist to the classic Sudoku puzzle. Arrange the numbers 1-9 in the white squares using the surrounding clues that give you the sum (Σ) and product (Π) totals for each line. Each of the 240 puzzles involves entering the digits 1-9 in their correct position in the central squares, with no duplicates. The squares around the edge contain clues that allow you to solve the puzzle with a little mental math and logic. The top row and left column are marked ‘Σ’, indicating a ‘sum total’ for that row or column (i.e. a + b + c). The bottom row and right column are market ‘Π’ indicating a ‘product total’ for that row (i.e. a × b × c). Three levels of difficulty, 80 games per level.
