To remove every element from the board, drag a line. Even the most experienced players will be put to the test by the increasingly challenging levels, despite the concept’s apparent simplicity.
Throw a ball into patterns made up of three different kinds of elements: solid black elements that stay on the screen and that the ball bounces off; white geometric shapes that vanish when the ball touches them and bounces; and white lines that the ball passes through and disappears but does not bounce.
Each pattern’s objective is to remove every white element; the challenge is figuring out the angle to make the first (and only) throw so that the ball hits every element that needs to be removed after bouncing off the different pattern elements.
The white shapes on the screen produce piano notes, the black shapes produce drum beats, and the white lines produce guitar sounds when struck, giving the game an additional dimension.
As the game goes on, each pattern’s right answer results in a straightforward yet unique melody. The game’s strength is that, aside from the initial patterns, none of them are easy; throwing and calculating trajectories require a great deal of accuracy.
