List of Cyberchase episodes

Cyberchase is a math, environmental sciences, and meteorology cartoon on PBS Kids. Cyberchase features Jackie, Matt and Inez (earth children) who use math and problem solving skills in a quest to save Cyberspace from an evil villain named The Hacker. The three are zapped into Cyberspace by Motherboard, the ruler of Cyberspace. Together with Motherboard's helper, Digit (a cyberbird), the three new friends compose the Cybersquad.

Each episode ends with a live-action For Real segment, hosted by young, comedic actors who explore the show's math topic in the real world. Cyberchase is created by Thirteen Education for WNET aka Channel Thirteen.

After the 5th episode of Season 8, Cyberchase was put on hold, due to executive reasons. However, on April 3, 2013, it was announced on the official Facebook page that the show would return for a 9th season during the fall.[1]

Season 1: 2002

In the pilot episodes, "The Poddleville Case", and "Lost My Marbles", Hacker infects Motherboard with a computer virus. At a library on Earth, while looking at a computer, Jackie, Inez, and Matt (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 109, Buzz and Delete nearly retrieved the encryptor chip, but lost it in a dust storm, much to Hacker's discomfort.

Summoned by Motherboard, the kids and Digit arrive with the knowledge that Hacker has taken Marbles to a castle, but which one? Using Data – Data is a lot more than a collection of numbers. When you gather it, organize and analyze it, you can discover useful information hidden in the numbers.
3 103 R-Fair City January 23, 2002 Hacker lures Digit to R-Fair City and holds him captive. When the kids arrive, they analyze the games of chance, figuring out which games are fair and which ones are not.

Note: This was the first episode produced; the animation style, voice acting, musical score, and even the "For Real" segment is vastly different from any other episode, and this is the first episode that Digit does not appear in. This episode was the original pilot and was animated by Curious Pictures.

Patterns – Patterns are sequences that repeat or change in an orderly way. You can use patterns to predict the next step in solving a problem.
8 108 And They Counted Happily Ever After January 30, 2002 Hacker kidnaps the King of a fairy tale Cybersite called Happily Ever After, and demands a ransom of golden eggs. Wicked casts a spell, taking away everyone's ability to count and making it impossible for the fairy tale folk to gather the requisite eggs.

12 112 Of All The Luck February 5, 2002 Hacker collects the Ten Lucky Charms of Cyberspace. Hacker's luck changes, and good things begin happening to him. When Motherboard realizes what Hacker has done, she sends the Cybersquad to Hacker's hideout in the Northern Frontier to help the Lucky Charms escape. Logic – When you have to choose from a confusing mix of possibilities, you can use logic – a set of tools for thinking clearly – to picture and refine your choices so you can get exactly what you want.
13 113 Eureeka February 6, 2002 The kids must try to find Archimedes, so he can provide a backup Encryptor Chip. Meanwhile, Dr. Marbles tries to evade Hacker and crashlands on Mobius. 2D and 3D Geometry – When you follow simple rules to make flat geometrical shapes, and join them together, you can discover new shapes that, instead of staying flat, rise up to make three-dimensional objects!
14 114 Cool It February 7, 2002 When Hacker's plan involving Buzz and Delete to steal all of Motherboard's cryoxide succeeds, the Cybersquad uses their knowledge of volume to calculate the amount of cryoxide they need to purchase from Castleblanca before Motherboard overheats. Liquid Volume – Just because one container appears 'bigger' to the eye does not mean it holds more liquid than another. A container's volume depends on all its dimensions.
15 115 Find Those Gleamers! February 8, 2002 In order to retrieve Motherboard's Encryptor Chip from Hacker, they accept Hacker's challenge to catch power-up bugs called gleamers that Hacker released on Topsy Turvy Island. Using their knowledge of multiplication, they must collect enough gleamers to power up another version of the Grim Wreaker and escape with the Encryptor Chip before sunset when the island turns inside out. Algebra – When you use a letter to stand in for a number that repeats or changes in a problem, you can simplify the arithmetic and make the problem easier to solve. Note: This is the first time Matt calls Inez "Nezzie"
16 116 Codename: Icky February 11, 2002 With a plan to capture Aquari-yum's giant energy-feeding slug to drain Motherboard of her energy, Hacker heads off to Aquari-yum. To make matters worse, he has a secret device that can listen in on everybody's conversation. Using their ability to develop secret codes so that Hacker doesn't overhear, they must find Icky before Hacker does, or Aquari-yum will boil over without the slug, Icky feeding on its energy. Codes – You can use a code (a communication system that substitutes one thing for another) to send top secret messages as long as your code has an adjustable rule that can be reversed to read the message.
17 117 Return to Sensible Flats February 12, 2002 Hacker takes all of the water in Sensible Flats and the kids have to find the problem. Line Graphs – You can use a line graph to tell a story about how things change, and to make predictions.

Guest-starring Geoffrey Holder as Master Pi. Working Backwards – When you tackle a tough math problem, treat it like a challenging game. Your chances of solving it will be better if you follow a game plan, and the more you play, the better you will be at problem solving next time.
19 119 Send in the Clones February 14, 2002 The kids persuade Cy Clone to capture the clones of Delete that are causing chaos in R-Fair City. Multiplication – Stuck on a multiplication problem? Relax! Remember that multiplication is just repeated addition, and you can use what you already know to find the answer.
20 120 Trading Places March 14, 2002 During an unexpected game of cat-and-mouse while trying to rescue Dr. Marbles, the Cybersquad crash into a cybersite along with Hacker. The cybersite is known to use trading as its currency. With both of their ships destroyed, the Cybersquad must trade items to get parts to fix their ship and get to Dr. Marbles. Monetary Systems – Instead of trading what you have for what you want, you can make it easier to buy and sell by creating a system of money where you exchange goods for tokens of different fixed values.
21 121 Less Than Zero July 3, 2002 During an important meeting with all the Cybersites' leaders at the Cyber Grand Tower, Hacker appears and threatens to freeze every Cybersite with his Freezerator if they don't surrender to him. Using their knowledge of number lines, the Cybersquad is sent to rescue the Cybersites' leaders and stop Hacker. Negative Numbers – Numbers don’t have to stop at zero! Negative numbers — numbers that are less than zero — can extend the range of what you can measure on a scale and give you the ability to compare numbers using direction as well as amount.
22 122 Model Behavior July 4, 2002 Hacker uses an inside man to make sure the celebration in Happily Ever After continues. This ensures that Wicked will sing and her voice will cause the Skywall to break. Using Models – Make a model – a simplified version of something complicated – and you can easily and safely understand how it works.
23 123 Fortress of Attitude July 5, 2002 Hacker has created a giant statue of himself in the Northern Frontier, with a voice recording of himself inside its mouth, broadcasting it to all of Cyberspace in a loud voice, with the help of large speakers. The Cybersites are required to surrender to Hacker if they want it to stop. Using their knowledge of measurement, the Cybersquad must enter Hacker's statue and turn off the voice recording before it's too late. Linear Measurements – To measure length and communicate your results easily and precisely, identify a system of units based on a single standard length that everyone using it agrees on.
24 124 Size Me Up July 8, 2002 After being tricked by Hacker, the Cybersquad end up on a Cybersite, where everything is ten times larger or smaller than them depending on where they are on the Cybersite. Using their knowledge of measurement and comparison, they must find a portal and warn Motherboard about a catastrophic virus being sent by Hacker. Scale and Size – You can create an exact likeness of something—though one that is a different size—by multiplying the size of every part of your original by the same number.
25 125 A Battle of Equals July 9, 2002 When Hacker releases Cyberspace's most horrible garbage called Cyberstatic all over Cyberspace, the Cybersquad are called in to help out. Using their knowledge of basic algebra and the ability to balance scales, they must reverse the four Cyberstatic-releasing machines before Cyberspace is polluted. Balancing Equations – Like a scale in balance, both sides of an equation must have the same value, and you can use this property of equality to find the value of an unknown.
26 126 Out of Sync July 10, 2002 Hacker lures away the beast causing the rhythm in Mt. Olympus to be out of sync. Patterns in Music – You can use mathematical patterns to create and understand memorable musical rhythms.

Season 2: 2003

There are 14 episodes in this season. 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 #211, although he did show mutual feelings towards her in Episode #203, but once again, he became self-centered and cared less about her. In a way, the occurrences of Episode #211 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 rampad, causing more chaos, and thus the cybersquad returns to almost every cybersite. We also see more of the Wicked Witch. From this season on, Motherboard is more three-dimensional.

Notes:

Season 3: 2004

In the third season, the kids met 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. The most dramatic event in the season occurred in a two-part miniseries called 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 (which might be the reason that this one is orange and yellow, rather than dark pink and chrome as the old one had been), 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 of the future episodes.

Season 8: 2010

The Cybersquad now may face a huge challenge! Now Hacker may no longer be the only villain in Cyberspace. With a rejected ally of Hacker named Ledge (Alex Karzis) on the loose, things may not be as easy anymore. Season 8 premiered on June 25, 2010, with the Summer Challenge. Episode 804 introduced Ledge, the newest villain of Cyberspace. Ledge was originally 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 seems to impress Hacker initially, the machine eventually gets unplugged by Inez, 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 805, 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.
