Players gather around a craps table in a dimly lit room filled with slot machines and blackjack tables. A woman throws a pair of dice, then smiles as applause and jubilation erupts under the watchful eyes of a dozen security cameras overhead. The scene looks straight out of any Las Vegas casino, but it's not. The "players" are college students learning the ins and outs of the hotel-casino industry at UNLV's world-renowned gaming laboratory.
