Bump the Balls

Bump the Balls is a physics puzzle in which two balls must meet after you draw a line. Your drawing becomes part of the scene, and gravity then sends the balls moving around obstacles, dangerous objects, and mechanisms. Some puzzles accept a straightforward platform, while others need a carefully shaped route.

The game contains 100 levels, with new obstacles and more precise solutions appearing as the challenge grows. You can draw using a cursor or finger, then release to activate the physics. If a puzzle blocks your progress, a hint is available to help you find a possible approach.

Press an empty area and drag to draw a line.

Release the mouse button or your finger to finish the drawing.

Let gravity activate, then help both balls reach one another.

Use a hint when the current puzzle is too difficult.
