Mortal Kombat began as an arcade fighting game in 1992, and its cabinet sounds became part of the experience of queuing up to play in arcades. The insert credit prompt was a functional sound, telling players their coin had registered and a match could begin, but players soon associated it with the excitement and rivalry of arcade competition. As arcade footage, retro gaming channels and meme edits spread online, the short prompt survived as a shorthand for old-school gaming, still used to signal a challenge, a rematch or a nostalgic return to the arcade.
