One hundred courts, 800 cloth sacks of corn, 200 target boxes and 1,000 expected competitors will transform Chicago’s Soldier Field Saturday into a battlefield for the Midwest’s largest organized cornhole event.

Or if you prefer — largest organized bean bags or bags event.

“It’ll be like World War II, with bags dropping all around,” said Aaron Del Mar, organizer of the first Windy City Cornhole Classic, which is open to all ages and skill levels.

Three divisions are available for adults: competitive, social and first-time throwers, as well as a free 14-and-under division for younger baggers.

More than $5,000 in prizes will be given away, Del Mar said, including cash, free burritos from Chipotle and T-shirts.

The winners of each division will win free Chipotle burritos for a year and cash prizes.

Online registration at http://www.chicagocornholeclassic.com closed Thursday, but participants can sign up in person from 10 a.m. to noon Saturday. The cost is $75 for the competitive singles division; $150 for doubles; $30 for singles in the social division; $60 for social division doubles; $15 for first-time solo throwers; and $30 for first-time doubles throwers.

The brackets will be finalized once registration closes. The doubles tournament starts at noon, Del Mar said.

Ten rounds have been planned for now, he said, and it should take about two or three hours to narrow each division to a winning team.

Singles play will follow the doubles rounds.

Lauren Wols, a 21-year-old from Orland Park, will be playing in the first-time throwers doubles division. The game is known only as bags in her circle of friends, she said.

“I’d never even heard of cornhole before this,” she said.

Wols’ boyfriend will be tossing with a partner in the social division, and she thinks he has a pretty good shot at winning.

“He’s really into it,” she said. “I guess I’ll just have to wait and see whether the people in our division are really first-time throwers.”

The game is simple. Players stand next to their sloped box, which has a hole at one end, and toss a bag filled with corn, beans or some other material at their opponents’ box. If the bag goes into the hole, the player is awarded three points. If it lands on the board, they earn one. If it falls off the board or doesn’t quite make it (known as a sally to some competitors), no points are awarded.

If you don’t relish the idea of trying your first tosses in front of an expected 2,000 spectators, the tournament will also have eight local bands, a full concession stand and an arcade featuring Golden Tee’s new cornhole game.

The latter is only a small indication of the game’s growing popularity. The American Cornhole Organization, “the governing body for the sport of cornhole,” wants to develop a televised pro tour and is working with the producers of “Cornhole The Movie,” a comedy scheduled for release this fall, according to the organization’s Web site.

“We plan to establish our rightful spot in the American conscience, shoulder to shoulder with darts, poker and paintball,” the site states.

For Wols, those goals are lofty; she’s really just looking to have a good time Saturday.

“I’m really looking forward to it,” she said. “I think it’ll be a lot of fun; young people hanging out and meeting each other.”

Admission is free, but a $3 donation is suggested for Fathers Helping Fathers, a nonprofit organization based in Palatine.
