A lot or a little?

The parents' guide to what's in this game.

Educational Value

In Algodoo, kids use two-dimensional modeling to learn a variety of introductory physics concepts such as friction, gravity, and light. Once they have these basics down, kids can use their building skills and apply physics knowledge to create machines with interacting components such as gears, lasers, motors, springs, and thrusters. These creations can get surprisingly complex -- for instance, machines that sort objects by shape or mass, or even vehicles and games. Kids can use Algodoo to learn how to model natural and man-made phenomena and to take their scientific knowledge back and forth between simulations and the outside world.

Positive Messages

Supportive tutorial language and questions help kids build scientific thinking skills and confidence with physics and engineering.

Positive Role Models & Representations

There aren't any characters in Algodoo; it's purely a sandbox title, though community members can share projects and lessons with one another to teach and learn online.

Ease of Play

There's a lot of physics to learn and experiement with in Algodoo, but excellent tutorials and a 2-D, rather than 3-D, interface make it easy to get started and imagine new things to build.


Since Algodoo is a sandbox physics engine, users can model machines such as guns as well as the effects of force on people and on other creatures and objects. Consequently, some projects shared on the Algobox community have some violence.


Although there's generally little to worry about with Algodoo and its online Algobox community, some users can't resist modeling potty humor.


Algodoo is free to download and free of commericial content; if you want to support the developers, you can buy the game from the App Store.

Drinking, Drugs & Smoking

A few of the tens of thousands of projects shared through Algobox feature drug and alcohol references.

What parents need to know

Parents need to know that Algodoo is a 2-D physics sandbox. Kids can create and manipulate a variety of objects and mechanisms and change their properties using contextual menus. For example, in a given "scene," or file, Algodoo can model anything from a block of stone sliding down an icy ramp to a rocket car taking off in low gravity to a complex sorting machine or a computer that uses physical gates to compute solutions. It's also possible to make games in Algodoo. Algobox is a generally kid-friendly online community of users who share their projects. Mentors and teachers also can register to access and create physics lessons for Algodoo. Robust tutorials support beginners well, but users can get just about as complex as they want in two dimensions using the game's materials, properties, and math.

What's it about?

In ALGODOO, kids play as engineers, inventors, and scientists exploring (and building with) the cause-and-effect relationships among energy, objects, and materials. Friction, gravity, light, magnetism: they're all here for kids to discover as they complete tutorials and create "scenes" -- or playable scenarios -- that demonstrate scientific principles via the players' created models and mechanisms. There can be a lot to keep track of for those looking for a challenge, but it's also fairly easy to get up and running with something like a laser and a prism to engage kids and get them thinking about how our world works.

Is it any good?

Algodoo is a great entry point for learning physics. Because it's a two-dimensional sandbox, it's a much more welcoming experience than something like the popular three-dimensional physics puzzler Garry's Mod. It's easy to see how objects attach to each other or interact with one another in two dimensions as compared to three. Thorough tutorials help kids master the basics, and the Algobox community features plenty of projects from which to draw inspiration for more advanced work. The "lessons" section offers tutorials that teach discrete, specific topics in physics. Algodoo is like a Scratch for physics; it starts where kids are but can spiral up in complexity as they learn.

Talk to your kids about ...

  • Families can explore how kids can become digital creators with Algodoo.

  • Families can explore how real-world objects and energy sources -- such as prisms and flashlights -- interact with one another.

  • Families can explore local science museums and events to learn new ideas to test in Algodoo.
