Female dice virgins are a much sought after breed. When one appears, the veteran players will sometimes place bets for her to win her and her god's favors. Men who have never rolled the dice before will have bad rolls. We prize virginity in our female rollers and despise it in our males. Never open a table or be the first or only player at a table.
Dice are cold at a new table and have to be handled before they can warm up.
A wrong bettor at a table will increase the likelihood of the seven coming up. And the more wrong bettors at a table, the more the seven will come up. No one can beat craps in the long run because of its inherent negative expectancy.
