For the fourth consecutive month Nevada casinos have reported a year-on-year decline in their winnings.
April's figures show a five per cent decline, leaving the casino's winnings down compared with last year as punters tighten their belts to cope with the economic slowdown.
This left them with $1 billion (£500 million) after gamblers wagered $12.7 billion, a decline that mirrors the four-month slump in winnings.
Total winnings for the year are $10.58 billion - a 0.5 per cent drop on the same time last year.
Frank Streshley, Nevada Gaming Control Board Analyst, commented: "People are still coming in and playing. They're just not playing as much."
Elsewhere in the world, China's gambling capital Macau continues to go from strength to strength and is estimated to record a 28.8 per cent growth in revenue from its 2007 performance, according to Globalysis.
