In Response To: Rolling Dice (Bill Riles)

The current US Rules (at the chicagopoint website) have two dice randomization components: the shake and the toss+tumble.

4.1 RANDOM ROLLS. Dice are strictly a means of obtaining random numbers; any other use violates the rules and the spirit of backgammon. A legal roll consists of shaking the dice vigorously in a dice cup and then simultaneously tossing them out at a discernible height above the playing surface, allowing them to bounce and roll freely. Both dice must leave the cup before either die contacts the board; otherwise they must be rerolled. Between turns the dice shall remain in the dice cup with the cup kept in plain view. Alternatively, players may roll legally by casting both dice simultaneously through a baffle box.

Although many people claim to know how much shaking and tumbling is enough (the old "I know it when I see it" subjective claim), in fact I've never seen a study (statistically valid or invalid) on this subject.

If you limp through the rolling part then mostly what is left is the shake. For people who actually do vigorously shake their dice, that's one thing. Do you want the weak shakers to also include a weak 'toss' to get their (hopefully random) dicerolls?
