Looking around at the assembled group, he passes each girl and Michael a tin cup with three dice inside. "Now, the first part was physical exercise, to train the body, as well as speed training. This however will be a bit more cerebral, and in fact is one of the more unorthodox psychic exercises. Well," here he shrugs, "a part of it was because I didn't have the time to pick up tarot cards or chess sets. So instead, we will be playing a little gambling game."
Taking up his own tin, he places the dice inside. "The rules are simple. You roll the dice inside your tin, and keep them covered save or a brief peek after the cup is placed down. Then, you place a bet on the total of a rolled number, such as five fives, or twelve sixes. Of course, at the end of a round, all the dice are revealed, and the winner determined, if there is one. This is done in two stages. First, did they get exactly the number of dice they bet on? If they did, and no others did, they win. But victory goes to the one with the highest number value if there are two or more who made a correct bet."
He smirks just slightly. "The purpose, is calculated risk management. You have a number of dice with the results known to you, but must make assumptions on a known number of dice, but not on the subtle differences between them." He pauses for a second, hoping at least one of them, and with luck Michael, get what it applies to.
