Cyberchase is an American–Canadian^[1] animated mathematics series that currently airs on PBS Kids. The show revolves around three Earth children (Matt, Jackie, and Inez), who use mathematics and problem-solving skills in a quest 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 itself is created by the Thirteen Education division of WNET (channel 13), the PBS station for Greater New York.

After the 5th episode of Season 8 in 2010, Cyberchase went on hiatus. However, on April 3, 2013, it was announced on the show's official Facebook page that it would return for a 9th season during the fall.^[2]

On February 10, 2015, Gilbert Gottfried, the voice of Digit, announced that five new episodes were expected to be broadcast in the latter half of that year as the show's 10th season.^[3] In April 2015, the show's Twitter account retweeted a photo indicating that the season would focus on health, math and the environment.^{[4][better source needed]}

In January 2017, it was announced that Cyberchase would be returning for an eleventh season, with 10 new episodes set to air later in the year.^[5] In May, producer Kristin DiQuollo and director Meeka Stuart answered questions about the show in a 19-minute video.^[6]

In October 2018, it was announced that Cyberchase would air for a twelfth season. The season premiered with a movie special on April 19, 2019, with the remaining episodes set to begin airing in the fall;^[7] however, all but two of the episodes premiered in 2020.^[8]

Season 1 (2002)[]

In the pilot episode "Lost My Marbles", Hacker infects Motherboard with a computer virus. At a library on Earth, while looking at a computer, Jackie, Matt, and Inez (who accidentally let Hacker unleash the virus by touching the computer map at the same time) are sucked through an interdimensional portal into Cyberspace. In their first adventure, they go to an island to rescue Dr. Marbles. In subsequent adventures, they return to Cyberspace to thwart Hacker's evil plans, which vary from ruining Motherboard to trying to take over a Cybersite. Throughout the season, the Cybersquad searched for a new encryptor chip for Motherboard. In Episode 9, Buzz and Delete nearly retrieved the encryptor chip, but lost it in a dust storm, much to Hacker's frustration.

All episodes this season were directed by Larry Jacobs. "The Poddleville Case" was co-directed by Yvette Kaplan.

Season 2 (2003)[]

This season is a continuation of the same basic plot of season one. However, the focus on the search for the Encryptor Chip is shown less as the season deals more with a new scenario; each episode involving Hacker seeking to take over a cybersite or all of Cyberspace, or plot a nefarious scheme in which he is wreaking chaos and havoc somewhere. In addition, a continued appearance of Wicked, a witch from the cybersite Happily-Ever-After occurred, revealing her strong feeling towards Hacker, while Hacker only used her abilities as a witch to further his own evil tactics as seen in episode "The Wedding Scammer", although he did show mutual feelings towards her in "Harriet Hippo & the Mean Green", but once again, he became self-centered and cared less about her. In a way, the occurrences of "The Wedding Scammer" are the only of Wicked's evenings where she is successful with her affections. The character of Sam Vander Rom (Al Roker) is introduced in 204 and 208 and Erica Ram is introduced in 211, where she hosts Cyberscoop alongside him. In this second season, Hacker continues to run rampant, causing more chaos, and thus the Cybersquad returns to almost every Cybersite. The Wicked Witch also makes additional appearances.

All episodes this season were directed by Larry Jacobs.

Season 3 (2004)[]

In the third season, the kids meet Slider, a rebel-style skateboarder who lives in the cybersite Radopolis. He first appears in the episode "The Borg of the Ring" where he retrieved the Totally Rad Ring of Radopolis from Hacker. Once again and then a third time Hacker tries to take control of Radopolis, first by almost winning a competition, then by putting everyone except Digit, Slider, and the Cybersquad asleep so he fails. The kids are told his father, Coop, had abandoned him. Coop was on a distant cyber-planet, but the kids didn't know that yet.

This season contains the first two-part episode of the series, "The Snelfu Snafu". While Slider was searching for his father, he stumbled across the location of the elusive encryptor chip. When he alerted the Cybersquad, they soon discovered it was in the hands of an auctioneer. The kids eventually earned enough snelfus (the Cyberspace term for dollars) to win it, but they discovered the chip was infected to drain Motherboard, replacing her with Hacker. The kids were then placed in the dungeon at the new Hacker Control Central; when they escaped, they searched for the encryptor chip because Motherboard was trapped in it. Upon finding it, they also rescued Dr. Marbles. However, when they attempted to put the chip in the circuits, the hardware rejected it because Hacker has corrupted it. Dr. Marbles was forced to reboot Motherboard, destroying the chip in the process. This concludes the Encryptor Chip story-arc. Also, Hacker rejects Wicked, setting the stage for some future episodes.^[23]

Season 4 (2005)[]

The Cybersquad is at it again, and meets even more new allies like Fluff the Penguin. However, situations become more complicated now that Hacker is no longer the only villain attempting to rule Cyberspace; the Wicked Witch has been planning schemes of her own. On top of that, Hacker is now travelling all over Cyberspace to conquer unspoiled regions – and the Cybersquad soon learns that this may tie in with the disappearance of Slider's Dad. He steals the Electric Eel of Aquari-yum as a power source, and the Pedestal of Penguia as a relay for the power-flow, and combines these items with other gizmos and gadgets to form the Transformatron, a device with the capability of transforming anyone into anything. After taking the NIC (Network Interface Card) from Slider's dad, taking Coop (Tony Hawk) hostage, and kidnapping Slider, the device was complete. However, the Cybersquad was able to thwart Hacker's plans again by dismantling the device so it could not be used again and allowing the effects of the Transformatron to wear off.

This is the last season directed by Larry Jacobs, who had directed every episode up to this point.

Season 5 (2006–07)[]

At long last, Slider's dad comes home. However, simply because many of the parts used on the Transformatron before have disappeared does not mean Hacker has given up on it, so now the Cybersquad find themselves building, fixing, and inventing devices to stop Hacker from taking over. When the Transformatron goes on the loose, Digit and the kids must dispose of the NIC card, the only power source of Hacker's machine. New villains Olga (Annika Walter) and the Trashinator (Phil Collins) make their debut during this season.

During the season, a special two-hour program, "Cyberchase: My Big Idea!" was broadcast. The program comprised episodes 64–67 shown sequentially, and was built around the theme of inventions. Each episode covered a different invention topic. The program was hosted by Bianca and Harry from Cyberchase For Real! and in between episodes, they talked about inventions that were made by kids, and showed clips of kids who had made inventions of their own.

Len Carlson, as the original voice of Buzz, was replaced about halfway through the season by Philip Williams. Carlson died in 2006, and the episode "EcoHaven Ooze" was dedicated to him. This was the last season that was animated by Nelvana and the last one traditionally animated, before moving over to Flash animation by PiP Animation Services, starting with season six.

All episodes this season were directed by Jason Groh.

Season 8 (2010)[]

Season 8 premiered on June 25, 2010, and introduced Ledge (Alex Karzis), a fan of Hacker and was to get himself a place on Hacker's side to help take over Cyberspace. He tries to do so by making a machine that can turn everyone in Sensible Flats into "Hackerized" versions of themselves. Though this impresses Hacker, Inez eventually unplugs the machine, resulting an angry Hacker to cast Ledge away for his failure. This results with Ledge becoming Hacker's most dangerous rival. Aside from Ledge's failure, Hacker does not like Ledge because he heavily insults him and the possible fact that Ledge is less arrogant but more intelligent than Hacker, even though he is equally evil. The Cybersquad also does not like Ledge because of his deception that led almost all of them into danger in Sensible Flats he had caused by pretending to help them, as he thinks more wisely of his plans. It was then in episode 94, that Hacker and the Cybersquad were forced to work together to stop Ledge from stealing one of Hacker's previous inventions that can be used to help Motherboard, though the invention ends up being destroyed.

Fortunately for him, the little windy town of Bottowa has a powerful energy source that'll put new pep in his step. Unfortunately for the Bottowans, this power source is what raises the big ball at the stroke of midnight on Reboot Eve (like dropping the big ball in Times Square, but in reverse), and their celebration is being broadcast live across Cyberspace! When Hacker steals the energy source, Delete is so upset that he decides to stay behind and join forces with the CyberSquad, who have come to help the poor little town from Virtual World-wide humiliation. To do this, they'll try to harness the natural power of the wind and build a giant windmill. But will they be able to finish it all by the stroke of midnight?
