About this game

Bump the Balls is a physics puzzle where you draw lines to bring two balls together. Once your drawing is finished, gravity takes over and the balls start moving.

Each stage places hazards, spikes or rotating parts between the two balls, and your drawing has to account for all of them. On early stages a single flat ledge does the trick, but later ones call for ramps, walls and carefully shaped curves. Across 100 stages, new elements keep showing up and the margin for error shrinks. A hint is available if you are stuck.

You draw by pressing and dragging with your finger or the cursor, then release to finish. It plays on mobile and desktop.

It suits players who enjoy physics puzzles with creative solutions.

Keep your lines simple. A short, well-placed ramp is usually more reliable than a long, complex shape that can tip a ball the wrong way.

If it clicks with you, Royal Smash Puzzle Game, Arrow Cube 3D and Pics 2 Word are close in spirit.
