Emoji Charades is the fastest warm-up game that requires absolutely no preparation. A work phrase - a role, a process, a meeting type, a piece of jargon - is encoded as a sequence of emojis. The team has to guess what it says before the timer runs out. That's it.
The game works for the same reason charades works: decoding something together is inherently collaborative, and the moment of recognition is genuinely satisfying. It also works well on video calls because the emojis display on screen for everyone to see simultaneously, no screen-share setup required.
Use it as a two-minute warm-up at the start of any team meeting. Run three rounds for a quick team activity, or use it as a tie-breaker at the end of a quiz. No wrong answers, no stakes, and someone will always guess it in a way that makes no sense and turns out to be correct.
