MoxQuizz is a multilingual IRC quiz/trivia script for eggdrops which acts as a game master. A question is posted to the channel, and all chatter is searched for the answer. If something matches an answer or an optional regular expression, the user who said it receives a point. Highscores and an allstars table are managed. Users can ask their own questions, too. A large set of German and English questions are provided, but you can easily run MoxQuizz with your own set. There are numerous fun commands like !hug, !roll, and others.
