Plinko became famous as a pricing game on the American television show The Price Is Right, where it first appeared in 1983. Contestants drop chips down a large pegboard to win cash prizes based on where the chip lands. The format later spread far beyond television into online casino games, mobile apps, and streamer giveaways, where the bouncing chip is instantly recognisable. The short dropping sound is now borrowed for edits and videos that need a clear audio cue for luck, randomness, and a prize about to be decided.
