Goat Simulator turned “physics engine gone wrong” into a genre of its own: you drive a ragdoll animal through a small open world, headbutt anything that stands still long enough, and watch crates, barrels, and fences go flying in a chain reaction. We wanted that same slapstick chaos without an install, so we built Headbutt Havoc, a free browser game that runs right on this page. No download, no signup, no account.
Play Headbutt Havoc now
Tap start, drive into anything that is still standing, and hold onto your combo before the clock runs out. Best played with sound on.
How to play
You control Ruckus, a small horned critter with a short temper, in a yard full of crate piles, barrel rows, and a fence line. Drive with WASD or arrow keys on desktop, or the pad in the corner on a phone, and drag to look around with the mouse or a second finger. Press space, click, or tap the RAM button to charge forward and knock over anything close enough to reach.
Toppling several props in quick succession builds a chain multiplier, so the real skill is finding a cluster and ramming through it before the combo window closes. Each run lasts 60 seconds, and today’s yard layout is the same for every player, so a new one arrives tomorrow. Your best score is saved on this device, and nothing leaves your browser.
How it compares to Goat Simulator
Headbutt Havoc keeps the part people actually load Goat Simulator up for: driving a physics-driven critter around, headbutting objects, and chasing the satisfaction of a good chain reaction. The camera, the ram action, and the chaos scoring are all built to capture that specific loop in a session short enough to finish on a coffee break.
What it drops is everything Goat Simulator built around that loop. There is no open city to explore, no wardrobe of ridiculous outfits, no mutators, no missions, no multiplayer, and no story mode. Our yard is one small arena that changes layout daily, not a full world you can wander for hours.
If you finish today’s run and want more than 60 seconds of chaos, that is exactly when to get the real game. Goat Simulator has years of content, mods, and sequels built on the same idea we compressed into one page, and it is worth owning if the loop hooked you here.

Goat Simulator is on Steam for Windows, macOS, and Linux, with official mobile ports on Android and iOS. The PC version is where most of the content lives, including the expansions.
Frequently asked questions
Can I play Goat Simulator in a browser?
The official game requires a purchase and an install on Steam, or downloading the mobile app on Android or iOS. Headbutt Havoc, the game on this page, is our own original ramming game that runs entirely in the browser on phone or desktop, so you can try the core loop before deciding whether to get the full game.
Is this the real Goat Simulator?
No. Headbutt Havoc is an original game we built, inspired by the physics-chaos genre Goat Simulator popularized. It is not affiliated with, endorsed by, or connected to Coffee Stain Studios in any way. All art, sound, and code are our own, and the download links above point to the official Steam page and app stores.
Does the yard change every day?
Yes. The prop layout is generated from the date, so everyone playing today sees the same crate piles, barrel rows, and fence line, and it resets at midnight. Your best score for this device is saved separately and never sent anywhere.
Is it free?
Completely. No ads, no purchases, no account, and no data collection. Your score and settings live in your browser’s local storage.
Does it work offline?
Once the page has loaded, the game makes no further network requests, so it keeps working through connection drops. Goat Simulator itself needs no connection to play once installed, but installing and updating it does.
