Roopvi Line Balls is a mobile game focused on precision and timing. Players control the movement of a ball using a slider, navigating it through a series of obstacles. In "Air Rush," the goal is to move the ball up and down to avoid columns that move towards it. Colliding with a column results in the end of the game.

In "Cannon Storm," players control a cannon with a slider, shooting spiky balls to pop incoming balls before they reach the top of the screen. Failure to prevent a ball from reaching the top ends the game.

"Sky Lines" involves clearing spikes at the top of the screen by pressing them. The challenge is to ensure that balls flying from below pass through without hitting the spikes, as this causes the game to end.

Additional features include a history screen to track gameplay performance and a settings screen for adjusting audio preferences. Players can unlock different visual elements and backgrounds to personalize their game experience.
