Algodoo is a desktop 2D physics simulation tool that makes it easy to design, test, and visualize interactive experiments and playable scenes on Windows. The interface combines vector drawing, material presets, and real-time collision feedback so you can prototype ideas quickly without complex setup. Educators and hobbyists use Algodoo to demonstrate mechanics through hands-on play, pause and replay scenes, and measure forces with simple on-screen instruments. Built-in scripting, parameter sliders and joints let you automate object behavior and construct working mechanisms or simple games. If you are new, follow a step-by-step algodoo tutorial marble race to see how gravity, collisions and constraints come together in one project. For quick help, search beginner videos or articles that explain how to use algodoo in a classroom, covering drawing tools, motors, and friction settings. Try the demo version to preview features and sample scenes, then download the Windows installer when you are ready to save projects and export animations. The app runs smoothly on standard desktop hardware, supports sharing scene files, and includes measurement tools for labs and lessons. Whether you are teaching physics, prototyping gameplay, or tinkering for fun, this simulation lab turns ideas into interactive experiments.






Algodoo is seriously the coolest thing I’ve found in ages! Every day I discover new tricks and spins! If I could, I’d rate it higher! It’s just so appealing! Love, love, love!!
