Here is a simple game you can use as an icebreaker for Campaigners or any other get together.
Print out the link below and get a pair of dice. Take turns rolling the dice and answering the question with that number.
It is a simple game, it is fun because there is an element of a "game" and also you can get the same question in a row but in a fun way. Also people are anticipating what what someone might say if they roll a certain number. It keeps them focused.
