Cyberchase

A day at the library turns into an adventure when Jackie, Matt, and Inez learn that Hacker has kidnapped Dr Marbles.

Dr Marbles is captured by Hacker and taken to Castleblanca, a cyberspace version of Transylvania. To find Dr Marbles, the team must collect, organise, and analyse data.

Disguised as a gypsy, Hacker lures Digit to a cyber amusement park and holds him captive. When the kids arrive, they analyse the fairness of the park's games to outsmart Hacker.

Hacker steals the powerful sunisphere from Solaria, causing the cyberworld's sunny vacation paradise to be covered in snow, so the team use estimation to recover the device.

The team must measure Hacker's irregularly shaped property to prove that he has taken more land than allowed.

The team fail to prevent Hacker from stealing Pandora's box. Later, the team use fractions to complete Zeus' challenges.
