Kahoot is a game-based learning platform where players answer timed multiple-choice questions together, usually in a classroom or on a livestream. Its bright interface sounds, including the short cue between questions, became familiar to millions of students and teachers as the platform spread through schools in the 2010s. Creators later borrowed those cues for their own quiz, trivia and challenge videos, because the sound instantly signals a game is in progress and a new question is coming.
