SAN PABLO — The Texas Hold 'em poker craze has run its course at one East Bay gambling joint, and dozens of casino workers are losing their jobs because of it.

Lytton Casino San Pablo laid off 91 workers Wednesday as the casino cleared away 14 poker tables to make way for 100 lucrative new electronic bingo machines, bringing the number of machines at the tribal casino to about 1,200.

Doug Elmets, spokesman for the tribe, said two dozen of the laid-off cardroom and food service workers will have a chance to apply for new positions.

Since politics foiled the Lytton Band of Pomo Indians' plan for real slot machines five years ago, and the tribe turned instead to bingo-related machines that mimic slots, they have steadily taken over the sprawling gaming floor. Now only a distant cluster of pai gow, blackjack and other games remains on felt tables.

The tribe pays a 7.5 percent share of revenue to the city — more than $1 million per month in recent years.

"There is no question that business is good, particularly as it relates to electronic bingo machines and other table games," Elmets said.
