Get the balls into the goal! Each level contains a cannon that fires balls every second and a jar that needs a certain number of balls to complete the level. Click on the screen and drag to draw a line that the balls can bounce against to reach the jar. You only have a limited number of lines to draw, indicated by the icons placed at the top of the screen. To remove a line, click on it.

Each level has different obstacles to overcome. Some platforms in the level will be yellow, meaning they need to be unlocked with a golden key. A ball has to collide with the key to remove that platform. Blue blocks are ice cubes, and you need to set your ball on fire to break them! Any ball that touches the fire will ignite. Pink blocks will destroy balls. Green circles are portals that will teleport the ball.

In later levels, you'll get yellow multifaced cannons that will shoot balls in different directions. There will also be more than one jar to fill up.

If a level is too difficult, you can click the blue arrow in the upper-right corner to watch an ad and skip the level.
