What Is Brain Lines?

Brain Lines is a physics-based drawing puzzle game where you draw lines to guide a ball to its target. Each level gives you a blank canvas and a ball — sketch ramps, slides, or barriers to redirect the ball into the goal. Levels grow progressively more complex, introducing obstacles and tighter spaces that demand creative thinking.

How to Play

Click and drag on the screen to draw a line. Release to lock it in place, then watch physics take over. If the ball misses, erase your drawing and try a different angle or length. Reach the star or goal zone to clear the level. Some stages cap the number of lines you can draw, so plan before committing.

Controls

  • Click + Drag — draw a line
  • Erase / Reset — remove your drawing and retry

Tips

Shallow angles send the ball rolling further; steep angles build speed downward. Start with a single line whenever possible — simpler solutions almost always work better than complex multi-line constructions. Use the stage walls as natural redirects rather than trying to build your own deflectors from scratch.
