Bubble Piles
Your goal is to build same color bubble piles and defend them against falling cubes, spiky bubbles, and bubbles of different colors.
Spiky bubbles will completely destroy your piles.
You lose when three cubes pile up on any pile.
Just tap on the moving bubbles, cubes and spiky bubbles to remove them from their path.
The more piles you have to build simultaneously the more challenging it gets.
