Sum Sort vs HootDoKu

Sum Sort is the number puzzle where every column has to add up. Drag the top tile onto another column and make each column hit its number: 7 + 3 = 10, 5 + 5 = 10, 4 + 6 = 10. When a column reaches its number it turns green and the ≠ becomes =. Make every column equal and the level is yours! Simple to learn in seconds, deep enough to keep you thinking for months. It is the satisfying feeling of a sort puzzle, mixed with the light mental math of the best number games.
