Kahoot began as a game-based learning platform where players answer multiple-choice questions on their phones while a shared screen shows the question, timer, and scores. Its short answer and countdown sounds became part of that routine, signalling when time was running out and when a response had been locked in. As classroom games were recorded, streamed, and clipped for social video, the familiar chime travelled beyond school, becoming shorthand for quizzes, tests, and timed reveals in edits about learning, gaming, and trivia.
