The sound comes from Minecraft, the sandbox game developed by Mojang and first released in 2011, where experience orbs are glowing green and yellow spheres that add to a player's experience points. As Minecraft gameplay spread across YouTube, Twitch and short-form video, its most recognisable interface sounds were isolated and reused as standalone effects. The experience orb chime became a shorthand for progress and reward in gaming edits, tutorials and streams, and it remains popular because even viewers who have never played instantly understand its positive, level-up meaning from context.
