Ragdoll Playground

A free ragdoll sandbox you play right here: grab a crash-test dummy, throw it, crash a car into it or blow it up, and watch the damage add up. No download, works with a mouse or a finger.

How to play the ragdoll sandbox

  1. Grab is on when you start. Press on any part of the dummy, drag, and let go to throw it. Grabbing the head or a foot swings it differently.
  2. Pick another tool and tap the playground: Dummy adds more ragdolls, Crate and Ball drop things on them, Car adds a car that drives toward the middle, and Boom sets off an explosion where you tap.
  3. With Ramp, drag a line to build a fixed ramp or wall. Erase removes whatever you tap, including ramps.
  4. Every hard hit adds to the damage counter in the corner. Very hard hits break a bone (CRACK!) or knock the dummy out. Your best score on each map stays in your browser.

Keyboard shortcuts: 1 to 8 pick the tools in order, S slow motion, G zero gravity, P pause, R reset the map.

Tips for a bigger damage score

How the ragdoll physics works

Each dummy is made of 11 rigid parts: head, chest, pelvis, upper and lower arms and upper and lower legs. They are pinned together at the neck, shoulders, elbows, waist, hips and knees, and two softer links stop the neck and waist from folding flat. Gravity, momentum, friction and collisions are handled by the open-source Matter.js 2D physics engine, running 60 times a second in your browser.

The damage score is worked out from how fast a body part was moving relative to whatever it hit. Small bumps score nothing, so a dummy lying still does not keep adding points.

FAQ

Is Ragdoll Playground free?

Yes. It runs in your browser for free. There is nothing to download, no account and no in-game purchases.

Is there blood or gore?

No. The ragdolls are cartoon crash-test dummies. They turn red where they are hit and show a crack mark on a broken bone, nothing more.
