Sumdoit is great fun for children, math wizards and everyone in between. It only uses single digits from 0 to 9 and no equation is greater than 20. Sumdoit uses simple math to improve your speed, problem solving and focus skills. It has 3 main levels, 2 x 2, 3 x 3 and 4 x 4 grids with 4 levels for each, Easy, Difficult, Extreme and Insane. Your children will love the 2 x 2 and you the 3 x3 and for those of you who excel in math the 4 x 4 will give you the challenge you are looking for.
