It's game on Saturday for the first round of volunteer applicants stepping into the Minnesota Super Bowl "Crew 52" headquarters on Nicollet Mall.

Candidates will arrive to music, hoopla and greetings from the gregarious Chad Greenway, the retired Minnesota Viking and a Crew 52 booster. He will officially open the doors inside City Center to the ground-floor volunteer space after an energetic welcome from Super Bowl Host Committee CEO Maureen Bausch, former Minnesota Vikings cheerleaders and the Skol Line musicians.

"Help us make Minnesota shine," Bausch says to prospective volunteers in a welcome video.

On Friday, Host Committee volunteer director Elle Kehoe gave a preview of the space that will be the heart of what organizers hope will be a warm Minnesota welcome for every Super Bowl visitor.

The volunteer home will be a test of the Host Committee's Super Bowl LII effort. For the past two-plus years, much of the action — fundraising and planning — has occurred behind closed doors in private meetings.

Now the public gets in on the game in a big way. The success of the "Bold North"-themed Super Bowl rests heavily on bright-eyed, cheery volunteers to provide warm Midwestern hospitality for an estimated 1 million visitors to parties and events. On Friday, the headquarters was quiet and empty with couches, tables, memorabilia displays and a selfie booth awaiting the buzz.

Some 20,000 have applied for 10,000 volunteer spots — and the committee is still taking applications through its website. Act fast, however, because the committee is conducting interviews through September. Candidates must sign up for interview times after submitting applications and all of the August slots are full, Kehoe said. Walk-ins are not allowed.

A crew of 100 screening specialists and support staff will welcome the first wave of 80 interviewees at 9 a.m. Saturday. Face-to-face interviews will continue through the day and then three days a week for the next two months. Prospective volunteers will watch a welcome video featuring Bausch and Greenway.

The goal is to "put Super Bowl 52 in the history books as one of the best ever," Bausch said.

Kehoe said the committee wants outgoing volunteers who engage in conversation.

Volunteers are needed for five general categories: hotel host, skyway host, Super Bowl Live host, Mall of America host and volunteer headquarters support. By far the most volunteers are needed for Super Bowl Live, the 10-day free event with music, food and activities on Nicollet Mall.

Kehoe said 1,500 volunteers a day are needed on Nicollet Mall. They must be able and willing to stand outside for three- to four-hour shifts, bedecked in the free Super Bowl LII uniform they'll receive, including a parka that will withstand the weather.

On their applications, volunteers are asked to identify their top three choices.

One caveat: No volunteers will be needed in or around U.S. Bank Stadium on game day, Feb. 4, 2018. The NFL handles those gigs.

As they exit, prospects will have their picture taken and get a free deck of cards featuring the blue and purple Super Bowl LII logo. Accepted candidates will receive notification in October. Training will occur in January.

The headquarters is in the former Sports Authority store on the corner of Nicollet Mall and S. 7th Street.
