Tom says at the end that no play testers ever split the money even. I assume that the playtest did not use real money and I think that makes the difference. In the playtest the aim of the game is to get the most "money" and win the honor of being the winner. At no point in the playtest can people be genuinely mad at you for winning. Since the real show uses real money the paradigm shifts and you can suddenly loose a lot more (your social status) than just the money you don't take for yourself by splitting. It would be interesting to see this show with people being anonymous. With that said it was a great show. Loving the great content that is being put out at the moment!
