Same Bubbles - a matching puzzle game.
The objective is simple, pop all the bubbles with your finger. Simply touch any group of bubbles to pop them. A group is two or more adjacent bubbles of the same colour. However you need to think fast as the game is timed, and you need to meet score and completion objectives to proceed to more levels.
With many levels, and different board styles and sizes, plus varying slide patterns, regeneration, and colour sets, there are plenty of variations to keep taxing you.
One in app purchase unlocks additional content; 70 more levels, bigger score multipliers, bombs (for blasting away tricky areas with no groups) there is plenty to keep you going for hours....
.... or minutes in the bus queue.
