Just Draw 3D

A squiggly line can become a bridge, a ramp, or a key — draw what's missing and see if physics agrees.

Just Draw 3D drops you into a small 3D scene with a simple goal: get a ball into a basket, protect a character from a rolling boulder, or smash a vase. The catch? A crucial piece of the environment is missing. Your job is to sketch that piece with your mouse or finger. The game instantly turns your scratch into a solid object, so a quick doodle becomes a functional ramp, a support beam, or a barrier. It's all about figuring out what the level needs and then convincing your shaky line to do it. The physics are forgiving but not stupid. Draw a flimsy line and it will bend or snap; draw a chunky rectangle and it holds steady. I kept coming back because there's a quiet satisfaction when your ugly doodle works perfectly. I once spent five minutes on a level where a triangle drawn just slightly off made the ball roll backwards instead of forward. Not every drawing has to be art — a wobbly curve works as a ramp if you angle it right, and some of my most effective solutions looked like a toddler's scratch. Levels switch things up with moving parts, fragile objects, and multi-step solutions. A few puzzles let you draw multiple pieces, which opens up weird strategies like building a trap or a counterweight. There are no timers or penalties, so you can experiment until something clicks. It's a chill brain teaser that feels more like doodling in a notebook than solving a strict puzzle. Perfect for a quick break between classes or meetings.

Drag to draw.

Draw thicker lines for sturdier structures — thin lines snap under weight. Watch where the object will fall before you commit to a shape. You don't need artistic skills; a rough rectangle can work as a ramp. If your drawing fails, tweak the angle slightly instead of starting over. Some levels let you draw multiple pieces, so use one as a support or counterweight. Try drawing a wide, shallow curve for rolling balls — it's surprisingly stable.
