Cyberchase

A day at the library turns into a cyberventure when Jackie, Matt, and Inez learn that Hacker has kidnapped Dr. Marbles, the only person who can save Motherboard from an evil virus. The rescuers learn to use a map as a mathematical tool as they navigate across a cyber island in search of Marbles—then try to escape before a huge earthquake turns the island inside out.

Cybersquad must stop Hacker from activating his newest creation, Gigabyte, before the light of the midnight moon, or else Dr. Marbles mind will be transferred into the monster, and Hacker will learn about all of Motherboard's secrets. The kids and Digit know Hacker is in a castle on a spooky, Halloweenish site called Castleblanca. Unfortunately, Motherboard wasn't able to specify which castle he is in. The kids must survey the residents of Castleblanca to pinpoint the exact location where Dr. Marbles is being held captive.

Digit is lured to R-Fair City, a cybersite full of carnival games, where he is kidnapped by a disguised Hacker. The kids must find the unfair/crooked game to find Digit. Meanwhile, they learn about chance and how to spot an unfair chance of winning and losing. Along the way they meet Lucky, a cab driver, who offers them a chance to gain a free cab ride while they search for Digit. Digit is locked in a bird cage with Buzz and Delete as his guards.

Hacker is looking for an eternal power source, so he steals Solaria's Sunisphere. The Cybersquad has to get it back before the whole site freezes over.

Hacker participates in a land rush in which participants cannot build property bigger than Judge Trudy's land. Hacker's land is accused of being bigger than Trudy's, but they turns out to be the exact same size.

The kids fail to stop Hacker from stealing Pandora's box in Mount Olympus, so they must solve a riddle and complete challenges to satisfy Zeus and earn a second chance.
