## What is Algodoo?

Bring your ideas to life with realistic physics in Algodoo. This creative and educational app lets you design two-dimensional scenes where objects move according to the laws of physics. See cause and effect in action and refine your builds to perfection.

Algodoo is a virtual 2D construction set to enjoy the creative thrill of building fun scenes and machines. You’ll never run out of parts. You can go deeper and analyse the motion and learn about mechanical devices. Once you master the tools and principles, you can build sandbox games or mesmerising, complex simulations.  

• Use basic 2D geometrical shapes or the free-hand drawing tool to create objects. 
• Combine components like axles, springs, motors, ropes, and lasers to create intricate machines.
• Choose from various materials—steel, wood, rubber, water, and helium—and customise at will. 
• Press “Simulate” to bring your scene to life, moving under the forces of gravity, aerodynamics, buoyancy, and more.
• Use trial and error to explore ideas and perfect your inventions.
• Express your imagination with vibrant colors, shapes, and textures.

Looking to build animations, contraptions, marble races, moving structures, chain reactions, or virtual science experiments? With Algodoo, the possibilities for invention, creativity, and exploration are endless.

With the Quick Tour and tutorial videos, you can easily learn Algodoo’s basic tools and principles. It's not just for fun— the scientific foundation of Algodoo makes it a great teaching and learning aid for exploring physics concepts, operating principles of machines, and even construction.

### 4/5 — Considerations

*2026-08-08, version 2.2.4*

This is a really great app. I ran into challenges registering in the online forum as there was no visible key to enter. I would prefer to post in the forum, but am doing so here. This is not a review but a response to a feature that is not working properly. Control click(multiple select) is not working on my ipad keyboard. There is no physical way to multiple select either, therefore I cannot edit the pieces in my project and manage interactions properly. This is a must fix in my opinion. Box selection does not work when you have even a slightly complicated setup. Consider adding a physical button for multiple select or better yet a keyboard shortcuts menu. A lasso tool might work too. Thanks for listening.

### 5/5 — Great physics sandbox

*2026-08-06, version 2.2.4*

Has all the tools required to make basic physics simulstions

### 2/5 — Algodoo

### 1/5 — Most good, some bad

*2026-08-03, version 2.2.4*

The game isn’t the best I’ve seen, however it is pretty educational and fun, however there is a problem where sometimes it just kicks me off, and doesn’t save me progress on a build. And another thing, sometimes my most recent save file loads and isn’t there, it’s just the default background but no builds at all, apart from these minor inconveniences, I generally like the game for its uniqueness and how you can create basically anything and everything. 4/5 stars 👍

### 1/5 — Not connecting

*2026-07-30, version 2.2.4*

I was trying to make something important than I decided to make a war then the tank parts didn’t connect and that’s why it didn’t connect to the lines, while I tried to hide the app, I didn’t work now so I need to find a way to connect it.

### 2/5 — great! but..

*2026-07-30, version 2.2.4*
