Play Draw That Line Online Free

About This Game

Two lonely balls sit apart on each screen, and only your pen can reunite them. Sketch any line or shape, let gravity do the rest, and guide both spheres into a single bump to clear the stage. The freedom is the fun: a straight ramp works, but so does a wild spiral, a leaning wall, or a scribbled bowl, and the engine treats every stroke as a real object. Early levels teach gently while later ones demand real imagination about slopes and momentum. Failures cost nothing, so experimenting stays joyful. A creative physics sketchpad for kids, artists, and anyone who wants to solve a puzzle with one perfect doodle.

How to Play

Hold down the mouse button or keep your finger pressed to draw lines and shapes directly on the screen. Release to let physics take over, and steer the rolling balls toward each other until they touch. Any drawing counts, so experiment freely and redraw whenever you like. Tip: angled V shapes catch rolling balls better than flat lines.
