Minecraft is a sandbox game developed by Mojang in which players collect experience points from mining, fighting and other tasks, and the level-up chime plays when enough points fill the experience bar and the player advances a level. The sound became familiar far beyond the game as gameplay videos, streams and short-form edits reused it to signal progress, and creators soon borrowed it for non-gaming content too. It remains popular because it is short, instantly recognisable and carries a clear sense of reward without needing any explanation.
