Broken Bones IV is the ragdoll physics classic where the whole point is to hurt yourself as spectacularly as possible. You fling your character off a cliff, crash into rocks and ice, and get paid for every bone you break. It sounds simple, and the first few falls are. The depth comes from learning how to chain abilities and trigger brain damage for massive payouts.
With over 1.3 billion visits and around 5,600 players online at any time, it's one of Roblox's longest-running physics games for a reason. This guide walks you through your first session, explains how cash and brain damage actually work, and shows you how to start earning serious money fast. For free in-game perks along the way, our Broken Bones IV codes page stays updated.
Don't overthink your first few drops. The game rewards experimentation, and you'll learn the physics faster by falling than by reading. Here's the order that gets you earning quickly.
Inside half an hour you'll have a feel for how to steer and where the good crash spots are. The early grind is quick because every fall pays something, even the bad ones.
The entire game runs on one loop: fall, break bones, get cash, upgrade, fall harder. Understanding what actually pays out is what separates a 20-dollar fall from a 500,000-dollar one.
Bones and joints are your bread and butter. Your skeleton has a fixed number of bones to break and joints to dislocate, and each one adds cash when it gives out. Faster impacts and harder surfaces break more at once, so building speed before you hit something is always better than a gentle tumble.
Brain damage is where the real money lives. When you slam your head into terrain at roughly 150 to 250 mph, you trigger a four-stage chain: Concussion, then Hemorrhage, then Brain Damage, then Ligmatization. Hitting the Brain Damage stage pays around $100,000, and pushing all the way to a full Ligmatization rewards about $500,000 in one shot. That's more than dozens of normal falls combined.
The trick is that the chain needs sustained head impacts at high speed. Bouncing your head once won't do it — you need to keep your skull connecting with hard surfaces as you tumble, which is exactly what the right abilities and crash spots set up.
Abilities are unlocked by leveling up, and they're the tools that turn a flop into a fortune. You'll get the most important ones early, then unlock increasingly chaotic options as you climb.
| Ability | Unlocks At | What It Does |
|---|---|---|
| Firework | Level 2 | Launches you up, then fires you in a direction for extra height and speed |
| Dart | Level 5 | Holds your momentum for a few seconds so you keep your speed into the crash |
| Sprung | Level 16 | Disconnects your body parts and reattaches them with springs for extra bounces |
| Smackdown | Level 25 | Raises you up, then slams you downward at high speed for a heavy impact |
| Gravitate | Level 45 | Removes gravity and lifts you for a few seconds to set up a big dive |
| Timeflip | Level 66 | Sends you back to a previous position mid-fall |
| Revert | Level 90 | Returns you to your starting location |
| Mitosis | Level 100 | Duplicates your body into clones for multiplied damage |
| Obliterate | Level 200 | Disconnects every body part and smashes them around erratically |
The two that matter most early are Firework and Dart. Firework gives you the launch, and Dart preserves the speed you build so you arrive at the rocks fast enough to trigger brain damage. Everything after that is a bonus.
Most new players leave money on the table by playing too cautiously or chasing the wrong upgrades. Steer clear of these and you'll progress far faster.
Once you've unlocked Firework at level 2 and Dart at level 5, you have everything you need to start farming brain damage. The combo is the backbone of every high-earning run.
Launch with Firework to get airborne, then fire yourself toward a rocky section of the map. As you start falling, pop Dart to lock in your speed so you don't slow down before impact. Aim your head into the rocks and let the brain damage chain stack. Done right, a single launch can carry you from Concussion all the way to Ligmatization.
The most reliable farming spot is Mount Zaquilla level 9. Hit the ice, empty your helium, and slam your head into the rocks at the end of the map. That sequence rapidly cycles you through the brain damage stages and routinely pays out the big numbers. If you prefer a different map, the same principle applies anywhere with dense rocky terrain — trees in Mount Zaquilla also trigger brain damage frequently.
Broken Bones IV is generous with cash, so you don't need to spend a single Robux to enjoy it. That said, a couple of game passes genuinely speed up progression if you plan to play long term.
The 2x Money pass is the one worth buying first. Doubling every payout permanently means you unlock abilities and climb map levels twice as fast, and it pays for itself quickly if you farm brain damage. After that, passes that raise your maximum perk levels from 3 to 5, or cut your ability cooldowns in half, give the most practical value for active players.
Skip the infinite cash pass unless you only want to mess around. It sets your money to maxed permanently, which deletes the entire reason to keep falling. The double-gravity and daily perk-level passes are situational extras — nice if you're a daily player, easy to ignore if you're not.

You launch your ragdoll off a cliff and crash into terrain to break as many bones and dislocate as many joints as possible. Every break pays out cash. Use WASD to steer toward rocks and slopes, and aim your head into hard surfaces for the biggest payouts.
Brain damage is a bonus status that triggers when you slam your head into terrain at roughly 150 to 250 mph. It stacks through four stages — Concussion, Hemorrhage, Brain Damage, and Ligmatization. The Brain Damage stage pays about $100,000, and a full Ligmatization rewards around $500,000 in one fall.
Use Firework (level 2) to launch, then dive head-first into rocky terrain. A reliable spot is Mount Zaquilla level 9: hit the ice, empty your helium, and slam your head into the rocks at the end. Chaining Firework and Dart speeds up the brain damage stages so you reach Ligmatization faster.
There are three maps — Mount Zaquilla, Sunken City, and Winter Horrorland — and each has 10 levels. Higher levels give more height and harder terrain, which means more cash per fall. Mount Zaquilla is the go-to map for farming brain damage.
Yes. The game has over 1.3 billion visits and holds around 5,600 concurrent players. It also has a sequel, Broken Bones V, and a Competitive Broken Bones IV mode, but the original remains the most-played version of the series.
