Super fans of Chipotle Mexican Grill can flex their puzzle muscles to win the famous burritos starting next week.
The restaurant chain will be celebrating their 20th anniversary with a three-week-long treasure hunt on http://Adventurrito.com.
The site will have a series of 20 online puzzles with daily prizes that will lead to the ultimate grand prize: free burritos for 20 years.
Prizes include free burritos for a year (one per week for 52 weeks) to 20 contestants each day and the grand prize of free burritos for 20 years (one per week for the next 20 years).
The contest begins on July 13 at 20:20 MTN time and continues for 19 days, unlocking a new puzzle each evening at the same time.
Puzzles will get progressively harder as the contest continues but purchase is not required to play.
Puzzle hints in the form of haiku poems will also be available to players who need a little extra help solving the puzzle. Hints can be unlocked by visiting any Chipotle restaurant and texting a unique receipt code found at the bottom of all Chipotle receipts to 30364.
Players will receive an additional entry in the next daily puzzle lottery drawing by referring a friend or by registering for the contest prior to the official launch on July 13.
The contest winners will be officially announced by August 15, 2013.
