such occasion, a giant Mr. Glitch ate Mathman as soon as the free game began. During Season 4, the format of the game was changed so that Mathman would have to decide if a certain statement (read aloud by the game's announcer) was true or false, and then eat the letter T or F. He would then have until the count of seven to make his decision. These were usually general-knowledge statements about math (e.g., "True or False? Mathematics and arithmetic are the same thing") rather than questions that required actual problem-solving skills. He had until the count of seven to make a decision in this version, but sometimes lost because he wasted too much time explaining his rationale for his decision before making it. Usually two or three correct answers would win a free game. Occasionally, Mathman did not play the game himself, making Mr. Glitch the contestant. If he answered incorrectly, he would be eaten by Mathman (or on one occasion, Mathman's dog Mathdog). On one occasion, Mr. Glitch got away with an incorrect answer, but on the second incorrect answer, he was eaten by a giant Mathman.

When he moved around the maze, he would repeat the phrase "Mathman, Mathman, Mathman," similar to Pac-Man's familiar "wakka-wakka-wakka". In a few episodes, Mathman was delayed arriving at the beginning so The Announcer gave the mission to Mr. Glitch. Mathman arrived later in Mr. Glitch's role as the nemesis. Mathdog Mathdog was Mathman's flatulent pet dog and wore a football helmet like that of Mathman. When he went around the maze, he would say "Mathdog, Mathdog, Mathdog, pfffft." Mr. Glitch Mathman's nemesis was Mr. Glitch, a cranky tornado who was always described with a different negative adjective. He was a parody of the multi-colored Ghost enemies of Pac-Man and would appear whenever Mathman had to make a decision. If Mathman ate an incorrect number or polygon, answered a question incorrectly, or used up too much time, Mr. Glitch would "power up" (with lightning
