A library of learning games
Learn by doing, one short game at a time.
Push a toy car on ice, take a leaf cell apart, stack rock layers, and find out how things work.

Why did Rafi keep moving when the car stopped?

How a game teaches
Here is what a game asks you to do. Not every game has every step.
Pick a question to explore
Each game starts from a question you might ask yourself.

One map of everything you can learn
Each subject is a place on the map, and each place holds games.
Built on how people learn
The games use ideas from research on how people learn. Not every game uses all of them.
How each game is made
A person and an AI write each game ahead of time. Two separate AI checkers then read the sentences we list from each game, and a game goes on this site only when each fact they find has a source that a checker has read. No AI runs while you play.
