Supercell is the Helsinki-based mobile developer behind Clash of Clans, Clash Royale, Brawl Stars and Squad Busters. Its logo splash screen, with a tiny audio sting, appears every time one of those games boots up, so regular players have heard the sound thousands of times. Editors lifted it from game launches and screen recordings, using it as shorthand for mobile gaming culture in memes, parody trailers and tier lists. It endures because the cue is instantly recognisable even at a fraction of a second.
