Nevada casinos posted a 1.8 percent gain in winnings during 2007 despite a soft economy, hanging onto USD 12.85 billion of the nearly USD 170 billion bet by gamblers during the year, according to a state report released last week. While the win was the lowest since 2002 and down from the 8 percent gain in 2006, Gaming Control Board analyst Frank Streshley said an increase during tough economic times shows the gambling industry’s resiliency.
