Episode Description: The Problem Solvers follow a musical clue back to 17th-century Istanbul, where math, music, and history collide at the workshop of legendary cymbal maker Avedis Zildjian. Using solfège, fractions, percentages, and number patterns hidden inside familiar melodies, the team unlocks a musical combination protecting a POG server. But teamwork — and patience — are tested as they race to shut it down before moving on to the next threat.

Episode Description: The Problem Solvers search for a hidden POG server in Oshkosh using Math, maps, and an unexpected clue from an old pneumatic tube system. As they calculate area, distance, and city blocks, tensions rise over trust, teamwork, and Charlene’s true motives. In the end, a forgotten underground system reveals a surprising connection between past technology and modern threats.

Episode Description: To stop the POGs’ prediction network, Max and Molly realize they need help—and fast. However, they are torn on whether or not they can trust Charlene.  To test her honesty, they recreate an experiment with a “lost” wallet stuffed with cash. Will Charlene pass the test?  As math, probability, and human behavior collide, the Problem Solvers learn that trust might be the most valuable currency of all.

Episode Description: During a break while playing Bingo – Max and Molly discover how probability shapes games of chance—right before a mysterious emoji message pulls them back into the hunt for the POGs. A hacked toy, a glitchy wi-fi signal from 1998, and a massive hidden server reveal the POGs’ terrifying “Prediction Calculator.” Now, the only way to stop them is to track their servers across time.

Episode Description: While warming up indoors on a snowy day, Max and Molly review their mysterious clues about the POGs—until Max’s Alexa begins acting strangely. Decoding a message leads them to the famous toy store, FAO Schwarz, in 1998, where they overhear a secret meeting of sinister toy avatars plotting chaos across time. To stop them, Max and Molly decide they must become… moles.
