Oh No U Di'n'T!!! is a gameshow game with a format similar to question-and-answer games. It's based on the first three seasons of the Cartoon Network Canadian animated series "Total Drama" ("Total Drama Island," "Total Drama Action" and "Total Drama World Tour"). The player must have some familiarity with the series to answer many of the questions correctly.
The player's only goal is to guess the name of each character contestant that one of the other characters decides to gossip about with the player. They begin the first four of eight questions by selecting the Start Gossiping button. They answer by selecting a character card.
If the player answers correctly every time, they receive 5,000 points. Otherwise, they start to lose points. If they need a second chance, they receive 3,333 points. If they need a third one, they only receive 1,667 points. If they can't guess the correct answer three times, they lose the game. They can track their status along the bottom of the screen. The game displays correct answers with green checkmarks and the incorrect ones with red Xs in white boxes.
Oh No U Di'n'T!!! rewards the player when they guess three characters correctly in a row. They receive a 30-second bonus round of fast questions. Correct answers award thousands of more points. The game might offer them a second bonus round if they answer three more questions in a row correctly from the last four of the eight questions.
It's important to note that this game might bother people who experience health problems when exposed to flashing lights because of a glitch that sometimes causes an onscreen spotlight and background colors to flash repeatedly.
