Supercell is the Finnish mobile game developer behind Clash of Clans and Brawl Stars, and this short intro sting is the sound players associate with opening those games. As gameplay clips, pack openings and funny moments from both titles spread across YouTube and TikTok, creators began using the intro on its own to signal a Supercell game before showing a clip. It remains popular because it is instantly recognisable to mobile gamers, even in just two seconds, and it immediately sets the context for a Clash or Brawl Stars video without any words.
