Add, subtract, multiply and divide! Time to give your brain a workout!
Sum Tracks returns in this sequel featuring eighty levels of basic arithmetic that will test your logic and help keep your mind sharp! In each level, click and drag the gray square tiles through multiple sequences of math operation circles so that the value of each square tile is zero.
Darker-toned circles must be used multiple times.
Hint: Some tiles may not zero-out in a single drag sequence!
