Science you can play with.
Launch projectiles, keep satellites in orbit, wire circuits, loop marbles and train a puppy. Every game comes with clear lessons that build up from first principles, so the “aha” moment sticks.

Launch Lab
Land the ball on the pad by changing angle and speed. Six missions on Earth, the Moon, Mars and Jupiter.
Orbit Keeper
Find the launch speed that keeps a satellite circling a planet instead of crashing or flying away. Six missions from the Space Station to Mars.
Circuit Rescue
Wire batteries, switches and bulbs to power up a dark spaceship. Find out why some bulbs glow dim and others shine bright.
Marble Machine
Build a marble run from ramps and loops and watch an energy bar show height turning into speed. Five missions, from a simple slope to a grand finale.
Train the Puppy
Train a virtual puppy to find its treat. You set the rewards and penalties, and watch it learn by trial and error. Five missions plus a maze builder.
Latest explainers
Short, clear reads to go with the games, plus hands-on activity guides.
Computers without computers: binary cards and logic gates
Unplugged activities for learning how computers work: count in binary with cards, draw pictures from numbers, and be a logic gate.
When rules run out: why computers need to learn
Some jobs are too messy to write rules for. See why, and how that leads to machine learning.
Data: turning the world into a table of numbers
Rows, columns, features and labels: how information is arranged so that a computer can find patterns in it.
Programs: talking to a computer
A program is an algorithm written in a language a computer can follow. See variables, if, loops and functions, and why bugs happen.
Algorithms: step-by-step instructions
An algorithm is a clear list of steps that solves a problem. Learn sequence, choice and repetition, and a guessing trick that is always fast.
Inside the machine: CPU, memory and storage
The processor, memory and storage each have a different job. See how they work together, using a kitchen as the picture.
