The aim of the game is to get rid of all the bubbles that are stuck on the pillar before they reach the bottom. Match the given colored bubble to any 2+ of the same colour to pop them and reduce the bubbles. By sliding to look around the tower, and tapping to shoot the bubble at its given trajectory. You can tap on an angle or straight in order to match with the rest of the bubbles. Being patient here is the key, along with using the right strategic movements.
