This collection comprises of a set of common objections to data sharing. There are two components. One is a pdf of common objections to data sharing, with suggested responses to these objections. The other are powerpoint slides for game of naughts and crosses (also known as Tic-tac-toe or X and O) based on these common objections to data sharing. Like the TV version, players are expected to win the square by, in this case, providing a satisfactory response to a data sharing objection. There are two versions of the game. One is a plain slide version, another is a version using a screen shot from the 1970s British comedy game show, "Celebrity Squares".
