The event: National Burrito Day is this Thursday, April 3.

Chipotle, the brand most responsible for putting the made-up holiday on the map, is bringing back its Burrito Vault digital game. The interactive promo will dole out up to 157,500 BOGO entrée codes. Last year, the game helped Chipotle notch its best-ever day for both overall and digital sales.

The copycats: Chipotle’s success hasn’t gone unnoticed. Competitors like Qdoba, Moe’s Southwest Grill, and even 7-Eleven are piling on with burrito-themed deals of their own.

• Qdoba is offering rewards members a free entrée with the purchase of another entrée and a drink.
