User Summary Art of Balance is a block-stacking, physics-based puzzle game with 100 levels distributed across four "worlds." The goal of each level is to stack a series of blocks so that they don't fall over. The blocks come in several shapes and the contours of the initial base vary as well. Later levels introduce new kinds of blocks (for example, that only support a limited amount of weight before breaking), and each world contains some special challenge levels (for example, creating a stack of a certain height).
