CARSON CITY — Nevada casinos had their 14th straight month of declines in winnings in February, reporting $830.9 million for an 18.1 percent drop compared with February 2008, according to a state report released Tuesday.

Taxes based on the casino win, a major revenue source for the state, totaled $65.1 million, up 22.6 percent compared with a year ago, according to the Gaming Control Board report. So far this fiscal year, those revenues amount to $478 million, down 16.3 percent.

“There’s a material decline in spending,” GCB analyst Frank Streshley said in releasing the report. “We’re still getting visitors, but the spending per visitor is down substantially.”

Streshley said the March win also may be down, but it’s possible that could mark the bottom of the big percentage declines and the casinos could start seeing small month-over-month gains or at least see their percentage slumps start to “flatten out.”

The $830.9 million win in February was the amount left in casino coffers after gamblers wagered $11.2 billion during the month, including $9.1 billion in slot machine bets and the balance on table games.

The GCB report shows declines during February in many major markets in the state, including the Las Vegas Strip which was down 23.5 percent.

Elsewhere in southern Nevada, North Las Vegas was up 21.9 percent, Laughlin was off 19.2 percent, downtown Las Vegas declined 11.4 percent, Mesquite was up 0.7 percent and the Boulder Strip was up 0.1 percent.

In northern Nevada, clubs in Washoe County, which takes in Reno, were down 23.4 percent. It was the 20th consecutive month of declines for the area.

Resorts on Lake Tahoe’s south shore reported a 26.8 percent decrease in February compared with the same month a year earlier.

A statewide breakdown shows that slots were off 10 percent while table games were down 31.6 percent compared with February 2008.

Slots accounted for $559.6 million of the total win. That included $267.1 million won by multidenomination slots, down 4.8 percent. Penny slots were second with a win of $142.1 million, up 5.9 percent.

Live games, including poker, accounted for the balance of the February total. That included $57.5 million won on baccarat, down 51.5 percent; $95.3 million won on blackjack tables, down 18.1 percent; $27.8 million on craps, down 39 percent; and $19.4 million on roulette, down 45.4 percent.

Sports books won $8.9 million, up 232 percent. More than two-thirds of the win came from Super Bowl betting activity. Poker games won $11.3 million, down 14.3 percent.
