<p>PHILADELPHIA - The bar is packed, the floor is wet, and dozens of glassy-eyed young people are squeezed around tables trying to lob Ping-Pong balls into cups of beer. </p>
<p>It is the final round of a beer pong championship, sponsored by a maker of portable beer pong tables, and all across the bar, as one team scores points, the other happily guzzles beer.</p>
<p>"It's awesome," said Chris Shannon, 22, a senior at Drexel University here. "If you win, you win. If you lose, you drink. There's no negative."</p>
<p>Drinking games have been around since Dionysus. But a whole new industry has taken off around them, making the games more popular, more intense and more dangerous, according to college administrators who say the games are just thin cover for binge drinking.</p>
<p>Some colleges have tried to ban the games on campus, but that has just driven them elsewhere. Many bars now hold beer pong tournaments like the one in Philadelphia, and some even have leagues and keep baseball-like statistics. </p>
<p>Urban Outfitters stocks a popular beer pong kit called Bombed and boxed sets of rules for other games. In January, thousands of players are expected at the first World Series of Beer Pong, sponsored by a beer pong accessories company and held on the outskirts of - where else? - Las Vegas. </p>
<p>This past summer, Anheuser-Busch unveiled a game it calls Bud Pong. The company, which makes Budweiser, is promoting Bud Pong tournaments and providing Bud Pong tables, balls and glasses to distributors in 47 markets, including college towns like Oswego, N.Y., and Clemson, S.C. </p>
