Bipo and Bolt in “The Star Workshop”
Episode 1Where Did the Stars Go?The Star Workshop

How it works

Start in under a minute

No sign-up: just a name (or a nickname) and an age.

  1. Choose a hero

    Six heroes, six series. Each one has its own season of 10 episodes.

  2. A short level check

    In the first sessions, Bipo finds out what your child already knows, so it starts neither too easy nor too hard.

  3. One episode a day

    About 15 minutes. Every right answer moves the story on; after a mistake, a step-by-step explanation appears.

  4. Progress and rewards

    Coins to dress up the robot, a companion that grows, and badges. Parents follow it all in the parent area.

The series

FAQ

Questions from parents

Is Bipo really free?

Yes, completely. There are no ads, no purchases and no subscriptions.

Which languages?

Portuguese (from Portugal), Russian, Ukrainian and English. You can switch at any time. Tasks and stories are read aloud: in the Windows version with Bipo’s own voice, in the browser with the voices installed on the device.

Does it work offline?

Yes. After the first visit, the browser keeps a copy of the game, so it opens even without a connection. The Windows version always works offline.
