COLUMBUS, Ohio -- The $400 million Hollywood Casino Columbus opened Monday in Ohio's capital, welcoming hundreds of people who had waited on a chilly morning to be among the first placing bets at the table games and about 3,000 slot machines.

It's the third and largest of Ohio's four voter-approved casinos. It also is the one that will have the most direct competition initially, as it sits about 10 miles from Scioto Downs, the first Ohio horse racing track to get slots-like gambling machines.
