Where this goes
Make a game other kids can play
These 30 concepts are the thinking underneath every game ever made: a command, a program, an order, a number, a bug you found yourself. In a Kubrio project your kid puts them to work on something real — with AI thinking partners at their side.
Ingenious projects that inspire kids to make things — until they find the thing only they could make.
Ages 6–13.
