How computers think, for 4 to 10 year olds

Before children write code, they need to think like a computer: step-by-step instructions, rules, and learning from examples. Whyzies teaches these ideas with a robot, a maze and a rule machine, plus why we always check what a computer tells us.

What your child practises

🔋

Robot maze

Plan the robot’s route with arrows, press Go and watch it follow your instructions.

🤖

Teach the robot

Sort examples to teach it, then check: is the robot right or wrong?

⚙️

Rule machine

🍎 becomes 🍎🍎 and 🐟 becomes 🐟🐟: so what does 🚗 become?

🦄

Real or pretend?

From “fish can climb trees” to “everything on the internet is true”.

How Whyzies teaches it

  • The robot maze starts with a single arrow for 4 year olds and builds up to longer plans around walls.
  • “Teach the robot” shows how computers learn from lots of examples, and that they can still make mistakes, so we check.
  • All the robots and computers games are free.

Try it at home

  • Play “robot”: your child gives you step-by-step instructions to walk to the kitchen. Follow them exactly!
  • Write the steps for brushing teeth together. Did you miss one?
  • Sort the washing or toys by a rule, and let your child guess your rule.
  • When you use a voice assistant or AI together, talk about checking whether it’s right.

Questions parents ask

What age can children start learning to code?

The thinking behind coding (sequences, rules, patterns) can start at 4 with simple games like the robot maze. Typing code usually comes later.

Does my child talk to an AI?

No. There is no chat and nothing connects to an AI. The games teach how computers work using pictures and simple rules.

Is it free?

Yes, all four robots and computers games are free, with no ads and no sign-up.

Ready to play?

Free for every family, with no ads and no sign-up. Grown-ups can set time limits and bedtime.
