The developer of a beach and tailgating game called MashBall won a $25,000 grand prize last week at New Orleans Entrepreneur Week’s Big Idea live-pitch contest.

In addition to MashBall’s Todd Mashburn, the contest’s finalists included the Sweat Social, a fitness services outfit developed by Rupa and Manoj Mohan for business and leisure travelers, and Scenehound, a smartphone app being developed by Michael Underwood to let users find out in real-time how crowded their favorite bars and restaurants are.

Separately, Sweat Social was awarded $20,000 worth of in-kind services by Peter A. Mayer Advertising.

Casting votes using $25 chips, participants picked among 10 local startups, with the three that collected the most chips competing in the pitch competition. Each contestant had three minutes to pitch their idea to a panel of judges, followed by a five-minute question-and-answer session.

More than 4,000 people attended the event, organizers said, allocating $49,000 in chips among the 10 startups.
