Lab Havoc is a destruction sandbox game where you are free to experiment with all kinds of crazy ideas inside a closed laboratory.
Lab Havoc was released by ZapGames in April 2026. It runs directly in your browser, requires no installation, and is completely free to play. The game is lightweight and easy to access, making it perfect for quick play sessions.

Lab Havoc gives you complete control over how you design your experiments. There are no strict rules, no fixed solutions, and no “right way” to play. You can place, rotate, and combine traps however you like, turning each setup into something uniquely yours.
What makes the game so engaging is how even the smallest change can completely alter the outcome. Moving a trap just a little or changing the timing can create a totally different chain reaction, making you want to test again and improve your setup.
The ragdoll physics system brings every experiment to life. Characters bounce, collide, and react in unpredictable ways, sometimes perfectly following your plan, and sometimes creating surprising results that are even more entertaining.
As you progress, you unlock more and more tools, from simple traps to advanced devices like lasers and gravity-based mechanics. This constantly expands your options and keeps the gameplay fresh, allowing you to build more complex and creative destruction setups over time.
