A sheet of paper is given to each participant with a grid on. This is a bingo card but instead of having numbers you have things like 'find someone who has 2 brothers' or 'find someone who was not born in this country'. The participants are free to go round the group, talking to everyone and see if they, for example, have 2 brothers. When they find someone who matches one of the things on the card that person should sign that box of the grid. The person who wins the game is the person who manages to have all the boxes in the grid signed.
