Summon your inner mathematician and solve complex equations by playing with a spinning cube that rotates faster with each level. The cube has letters on each vertex and you need to connect the dots, quite literally, by picking the right letters in the right order to form a word. Each level has a different word and the equations get tougher as you progress. Also, watch out for the time limit and the random blocks that flip when the cube rotates. They keep blocking your way until a bomb explodes or you find the key to the next door.
