Invisible Costume Party

Invisible Costume Party is a local multiplayer social/party game which requires running a local web sever. This makes it a little hard to share online, but the idea is simple. Everyone takes out their phones and connects to the local server. After choosing a username, they are given a secret invisible costume. The players must then act out their character without saying who/what it is. Players are also given a "target" character. The idea is to find your target, and also get found. You get a point either way. But every time you are found, you switch characters.
