Blooket is a web-based classroom game platform in which teachers set quizzes and students compete by answering questions to earn in-game characters, known as Blooks, and rewards. Its cheerful theme music became closely linked with school life as clips of gameplay spread across YouTube, TikTok and classroom videos, where students and creators reused the tune to signal a game starting, a win or a nostalgic school moment. Because so many players recognise it instantly, the sound still works as a shorthand for quiz games and classroom fun.
