You start out with balls bouncing in a room.
You have to contain the balls in order to advance to the next level.
To contain the balls you create walls (swipe up/down or swipe left/right to create a wall)
If a ball hits your wall before it is complete you lose a life.
Your lives are limited so timing is important.

There are 4 modes of game play.

1) Causal - no time limit, play until lives run out

2) Survival - same as Casual but you only have 1 life

3) Timed - You have a limited amount of time and lives to solve the level

4) Challenge - Once you complete a level, play it again to beat your personal best with your personal best as the timer.
