Sum Stacks
Sum Stacks is a free math-puzzle game. All the world is math and we are but mathematicians trying to figure out the algorithms, additions, and subtractions that make up existence. In Sum Stacks, you will use your unholy knowledge of arithmetic in order to add it up, subtract it down, and cut your way through level after level. In this game, you will be given a sum and some tablets. Your job is to use the tablets to subtract or add to a series of numbers in order to achieve the foregone sum.
