Brain Lines challenges you to solve each stage by drawing lines that redirect a bouncing ball toward its goal. The ball follows physics rules, so line angle and length determine how the ball bounces off your drawing and whether it reaches the target.
Early levels allow generous line lengths while later stages restrict how much you can draw, forcing creative minimal-line solutions. Anticipating how the ball will chain between multiple drawn surfaces is the satisfying puzzle-solving challenge.
Play Brain Lines free on ExcelGames.cc and draw the smartest path to every goal.
Click and drag to draw lines on the stage. Release to set the line in place. Launch the ball and watch how it interacts with your lines. If the ball misses the goal, erase individual lines or reset the stage and try a different approach angle.
