Viewers noticed several glaring problems with the episodes,
specifically, grammatical errors: "Who's" instead of "Whose", for example and factual errors - a question stated that hydrogen was the most abundant element in the Earth's atmosphere instead of nitrogen. Another question stated that Yahoo! is a web browser, instead of a search engine. There are also spelling errors. One question asked, "What is the main ingredient in tarter sauce?", instead of tartar in questions and answers. Some of these errors have cost contestants points. In one episode, a contestant was ruled incorrect for the quote from Passenger 57 (1992), "Always bet on black", which the contestant said. However, the show's answer was "Always bet on the black".
