Predictable Randomness

Grandpa Ross taught all his grandchildren to play poker and shoot craps. He didn't survive the Great Depression and WWII to leave his grandchildren to grow up to be fools. My sister, Judy and our cousins Jimmie, Debbie, and Joey; and sometimes other playmates, didn't just play the games, but bet on individual hands in poker and individual rolls in craps as a way of keeping score over sessions of play. We played for pennies, so there was no wealth accumulation incentive. These are games in which one person wins and everyone else loses in the individual rounds, but over time, wins and losses often accumulate to different sets of winners and losers.
