Feed the ‘hungry shapes’ by dropping similar shapes on them. The Shape which you are dropping can be different in color from 'hungry shapes', but they must be similar in shape. If a different shape is dropped, it will not be eaten and you lose a life. As game progresses, you will face more challenge which includes more ‘hungry shapes’, swapping positions of ‘hungry shapes’, increased speed of ‘falling shapes’, different colors of same shapes etc.
