If you want to play a physics-driven sandbox game that is fun, then you should give Broken Bones IV a try. In this game, you compete with friends (or yourself) to inflict maximum ragdoll damage and unlock exciting upgrades. The game has recorded over 1.3 billion visits so far and currently boasts a player base of over 5.6K. Let’s learn how to play the game.
How To Play Broken Bones IV – Ragdoll Sim
Let’s first understand the objective of the game: jump off cliffs, crash into terrain, and break as many bones as possible to earn in-game cash. Each broken bone or sprain adds cash. Go for multiple impacts by sliding or bouncing.
Hitting your head at high speed (150–250 mph) triggers Concussion > Hemorrhage > Brain Damage > Ligmatization. Brain Damage gives a huge cash boost (approximately $100k).
Once you crash into the ground, you will see your stats pop up on your screen. It will show the number of bones you have broken and which parts you have injured. According to the amount of damage you have inflicted, you will earn cash.

How To Get Ligmatization
A player can get Ligmatized by hitting their head at around 400 mph or more. When this happens, your screen turns pink. It only occurs after getting a Concussion, Hemorrhage, and Brain Damage.
The easiest way to get Ligmatized is by using Fireworks and Darts. Fireworks can launch you into the ceiling, and if they fling you into the ground, use Dart for extra damage.
