||This game exercises math skills by asking players to quickly combine numbers and operators to solve common arithmetic problems. Operators can be changed by tapping on screen, which cycles them in the following order: +, -, *, /, =. The goal is to put 5 blocks together and build an equation like 2 + 3 = 5. This works in all directions -- horizontal, vertical, diagonal and in reverse. When the player aligns blocks into correct mathematical expression, all five blocks get removed, freeing up the space for the blocks above. Arrows show directions in which each expression is evaluated.
