Muckleshoot Indian Casino,

the state's largest casino, is expanding to more than

200,000 square feet.

The two-story, 66,000-square-foot addition will allow the

casino to offer 1,500 slot machines, the maximum number

allowed in a tribal casino under an agreement with the

state, said Phil Ziegler, the casino's marketing manager.

The extra space, which is scheduled to be completed by

late December, also will include a restaurant that would

seat more than 300 people and office space for the Tribal

Gaming Commission, he said.

Tribal officials declined to comment on the cost of the new

addition.

The casino nearly doubled its size with a $20 million

expansion last year. The casino added 81,000 square feet

of space and installed a flashy video sign.
