About CalculaGames
Learn through play and experimentation
CalculaGames is a place to explore ideas by doing something with them. Play a game, change a variable, build a model, and see what happens. Our growing collection reaches beyond arithmetic into mathematics, physics, music, engineering, and creative experiments. The goal is to make difficult ideas visible, approachable, and worth exploring.
A studio for your own ideas
In CalculaGames Studio, you can write JavaScript, test it on a canvas, and turn a blank project into a game or interactive simulation. Built-in documentation and drawing, interface, and WebGL helpers support projects as they grow. Add a description and instructions so other people can understand what you made and how to use it. Anyone can try code in the editor; an eligible account is needed to save it to a private library.
Bring your own coding assistant
Adults can connect a compatible external AI coding assistant to one selected adult project through MCP. The assistant can read the saved code, descriptions, instructions, and runtime reference, then propose changes for review. Optional browser tests let it inspect errors, logs, and canvas captures while the studio stays open and testing is enabled. You decide which proposals to apply, test, and save. See the connection guide for setup and current capabilities.
Adult and family libraries
Adults can keep their own projects in a private library. Parents can also set up managed child profiles after completing the required verification and permission steps. Private saving and public sharing are separate choices: a child’s publication request needs a parent’s approval before site review, and public games require site approval. Coding-agent connections are available for adult projects. Visit My Account & Library to manage your projects and family setup.
Where it began
CalculaGames began with Calcula, a math game created as a Khan Academy project. It grew into a collection of games, then a studio where people can make interactive experiences of their own. Created by Samuel Sooter, a choir teacher, math enthusiast, and developer, the site brings together teaching, creativity, and a belief that learning becomes more meaningful when you can build with it.
You are the promised future.
The long-term vision is a welcoming place where learners become creators, share what they discover, and tackle increasingly ambitious ideas. You can start by exploring a game or opening a blank studio project. For account help, connection troubleshooting, or feedback, visit Help & support.
