About Flopbox

What is Flopbox?

Flopbox is a free ragdoll game in browser: a 3D physics sandbox set in a concrete test facility, where you pick a tool and use it on crash-test dummies. There are no levels, scores or timers. What the game is about is what happens to a body: every dummy has a skeleton, organs, vessels and a blood supply under layers of skin, fat and muscle, so the same tool gives a different result depending on where it lands, and you can look at the result with X-ray, a vitals panel and an autopsy view.

It has 20 tools and props, from guns to a tourniquet, plus lab modes with Moon, Zero-G and Jupiter gravity, freeze time and a photo mode. The current version is v1.1.1, released on 4 November 2026. Every release is listed on the updates page.

Who made Flopbox?

Where does Flopbox run?

In the browser, on a desktop or laptop with a keyboard and mouse, on a phone or tablet with touch controls, and with an Xbox, PlayStation or Steam Deck controller. It needs a current browser with WebGL 2. There is nothing to download, and a lighter classic version exists for slower devices. The how to play page has the controls and the fixes for a game that is stuck loading.
