List of Cyberchase episodes. Cyberchase is an animated mathematics series that currently airs on PBS Kids. The show revolves around three Earth children (Jackie, Matt, and Inez) who use mathematics and problem-solving skills to save Cyberspace from a villain known as The Hacker. The three are transported into Cyberspace by Motherboard, the ruler of this virtual realm. Together with Motherboard's helper, Digit (a robotic bird), the three new friends compose the Cybersquad.

Each animated episode is followed by a live-action For Real interstitial before the credits, hosted by young, comedic actors who explore the episode's math topic in the real world. The show is created by the Thirteen Education division of WNET (channel 13), the PBS station for Greater New York.

Between 2004 and 2005, five Cyberchase titles were released on DVD and VHS. Each DVD release of the titles contained three episodes.

iTunes 
iTunes Canada has released the first eight seasons, though they are not always according to the American airdates and use different season numbering. The Canadian releases also do not include the For Real segments, due to them not being included on Canadian airings of Cyberchase on CBC Television, Discovery Kids and the Knowledge Network. iTunes US has a collection of 24 random episodes, a couple of themed collections, and the two specials. See below tables.

Streaming 
The show is available to stream on PBS Kids' official streaming partner, Amazon Prime Video. The For Real segments are omitted.
