Poppy Playtime is a horror puzzle game developed by Mob Entertainment, with its first chapter released in 2021. Players explore an abandoned toy factory and use hand-shaped scanners to open doors, power machines and progress through puzzles. The hand scan cue became familiar through gameplay videos, streams and short edits, where its clean approval sound works as a shorthand for unlocking something. It remains popular because it is short, instantly recognisable and easy to drop into horror, gaming and reaction content without needing the full game context.
