Krystal has hosted eating contests since it first opened its doors in 1932. In fact Krystal's second customer, Roy Ward, claimed he could eat twice as many Krystals as French Jenkins, the chain's first customer. He did just that by eating 12 Krystals, and according to legend invented the Krystal Sackful in the process.

The years have passed, but Krystal Lovers have never stopped challenging each other to Krystal Eating Contests. This longstanding tradition became official in 2004 with the first Krystal Square Off World Hamburger Eating Championship.

The Square Off has become a "major" on the competitive eating circuit, with longtime Krystal Lovers taking on the world's best gurgitators.
