Balderdash is a game with 5 different rounds (words, dates, films, people and initials) The idea of the game is not to guess the real answer, although you get a point if you do, but to try to convince other people that your definition is the real definition.
Take the 'word round' for example, I post a word on a Sunday evening, the players make up a definition and PM it to me. On Wednesday all the definitions, plus the real one, get posted and everyone has until Sunday night to vote on which they think is the real answer. If someone votes for your definition you get a point. The person with the most points at the end of the 5 rounds is the winner.
We are a friendly crowd and we'll be happy if more people join the community.
