PINNACLE ENTMT (PNK)

LAS VEGAS, Nov. 7 /PRNewswire-FirstCall/-- Pinnacle Entertainment, Inc.
(NYSE: PNK) announced that it was informed by the Missouri Gaming Commission
today that the provisions of Proposition A are effective immediately. The
table games area at the Company's Lumiere Place entertainment complex is
already operating under the new provisions, which removed certain betting
restrictions for Missouri's casinos. Pinnacle believes that its slot machine
area will be prepared to operate under the new provisions by this weekend.
Also effective immediately, patrons are no longer required to sign up for a
players' card prior to entering the casino floor.

Additionally, Proposition A placed a limit on the number of casino
licenses available in the state and increased the tax on casino revenues from
20% to 21%. The tax increase, which became effective on November 5, is
expected to increase funding for Missouri schools by more than $100 million in
new net revenue each year.

Pinnacle believes that the approval will be beneficial to the Company, as
it will allow Lumiere Place to expand its marketing from a local customers'
complex to a regional entertainment destination. The Lumiere Place
entertainment complex currently features two casinos (Lumiere Place and The
Admiral Riverboat Casino); the Pinnacle-owned 200-guestroom Four Seasons Hotel
St. Louis; the 294-suite HoteLumiere; approximately 22,000 square feet of
meeting and convention space; several restaurants and retail outlets; and a
luxury spa.
