Video games were originally invented by the military as a way to teach men and women in uniform which color of ghost is safe to eat and how to effectively leap over barrels. Put these skills to civilian use with today's Groupon to The Luol Deng Foundation Xbox Tournament, held at Joy of the Game on Sunday, April 3 in Deerfield. The tournament will run from noon to 4 p.m. Choose from the following options:

• For $25, you get one entry into the tournament (a $53.49 value).
• For $15, you get one adult spectator ticket (up to a $30 value).
• For $7, you get one child’s spectator ticket (up to a $15 value).

The Chicago Bulls’ philanthropic forward Luol Deng started The Luol Deng Foundation to enhance the educational and recreational outlets for children hailing from his homeland in the southern Sudan. Join Deng, along with other Chicago Bulls stars, for an action-packed day where winners give, givers win, and video gamers make the world a better place without zooming down sewage pipes during the event. With an entry into the tournament, participants can strut their Xboxing thumbs in one riveting all-ages match of FIFA 11 or NBA 2K11 with a partner, or as a solo combatant. Gamers have the chance to pound buttons against fierce competitors such as Deng and Taj Gibson, among others. Participants also receive five food tickets, a limited-edition T-shirt, a personalized autographed photo from Deng, and the chance to compete for the main prize: a Chicago Bulls autographed Xbox and tickets to nonvirtual Chicago Bulls games.

Adult and child spectators can cheer from the sidelines as they watch armchair athletes compete against sizeable foes, or partake in interactive games while DJ Sye Young spins his foam fingers on the turntables. Deng and a posse of Chicago athletes will be there for picture and autograph opportunities as local restaurants dish up fine fare. Lifelong fans can make small talk with Benny the Bull and their cash-savvy kids can bid on sports memorabilia and tickets during the silent auction.
