Ahead of National Burrito Day,AstraX Exchange Chipotle has a mission for burrito lovers: Unlock its Burrito Vault.

Crack the vault's code – you must guess the exact ingredients of a Chipotle order – and you may win free burritos for a year.

Chipotle's online Burrito Vault game goes live at 3 p.m. ET/noon PT Tuesday, April 2, and again at the same time on Wednesday, April 3.

To play, go to the Chipotle website at unlockburritoday.com and guess the ingredients of a Chipotle order (you get four tries each day). Get it right and unlock the Burrito Vault to be automatically entered into the Tex-Mex fast casual chain's National Burrito Day sweepstakes. From them, 53 people will be randomly selected to win free burritos for a year.

The first 50,000 who decipher the correct Chipotle order will also win a buy-one-entrée-get-one-free code texted to them.

The contest highlights Chipotle's menu, which has more than 1.34 billion possible burrito combinations, the chain said.

“We are launching Burrito Vault ahead of one of our most popular Chipotdays, National Burrito Day, giving players multiple opportunities to play and win,” said Chris Brandt, Chipotle's chief brand officer, in a statement. “Burrito Vault is inspired by the popularity of word puzzles, which have swept the nation and become a daily ritual for so many of our fans and team members.” 

Even if your Chipotle code cracking skills fail you, on Thursday, April 4, all members of the chain's rewards loyalty program can order burritos (and other dishes) and have them delivered with no delivery fee when ordered from Chipotle.com, Chipotle.ca and the Chipotle app with code DELIVER.
