In a five-week showdown, eight renowned chefs will face the most-intense challenges that anyone has ever seen on Triple G. Premiering Sunday, Aug. 28 at 8|7c, Guy's Superstar Grocery Games takes the smart shopping and the competitive cooking to new heights. In this competition, the games aren't just the run-of-the-mill kind. When the caliber of chefs is so high, and the stakes this big, the challenges take on a new level of difficulty. Alex Guarnaschelli, Richard Blais, Jet Tila, Maneet Chauhan, Marc Murphy, Eric Greenspan, Damaris Phillips and Justin Warner enter the competition ready for what's to come — or so they think. When Guy's the gameskeeper, there's no telling what drama might befall the chefs. They'll have to strap themselves in for a ride on Guy's roller coaster.

Each episode will consist of two rounds. After the first cooking round, the judges will determine the least successful dishes. The chefs who cooked them will face a Sudden Death round, which will send one of them to the checkout lane. Every week one chef will say goodbye, until just four are left to compete in the finale for the chance to win $40,000 for the charity of their choice. Each week judges Troy Johnson, Carl Ruiz and Aarti Sequeira will decide who has the culinary creativity to advance to the next round, and who must leave via the express checkout lane. The one chef who can survive all of Guy's grueling challenges will be named the first Superstar Champion!
