The X-Y Game
A fun team game with real cash prizes.
Process: The delegates are split into groups with each team allocated two cards - one marked X, the other Y. At intervals the teams are asked to display a single card. Teams can win money depending on the inter-team correlation of results.
Outcome: Will the teams co-operate to guarantee the win or will they strike a solo path risk losing the safe bet in favour of the bigger win? This game has to be played to be fully understood, but once fully understood it is always a firm favourite.
