Crab Game is a free multiplayer party game released by developer Dani in 2021, built around mini-games inspired by Squid Game. Its Red Light Green Light mode adapts the children's game where players move on green light and freeze on red light or are eliminated. Clips and sounds from the mode spread through gaming videos, streams and edits, where the short command became a reusable cue for starting, stopping and trolling. It remains popular because almost anyone who has seen the format understands the rule from this one line alone.
