Here's how to get free Chipotle today

Users will be faced with a grid of 16 cards and a minute on the clock to match ingredients in a memory game. Click on the cards to flip them over and match garlic-to-garlic, cilantro-to-cilantro and so on. When users click the cards with additives, the time is reduced by five seconds every time they're clicked.

Even players who don't win the game have an opportunity to win the buy-one-get-one-free coupon. The coupon is valid until Nov. 30.

The game is based on the company's animated short film "A Love Story," which aims to show how, over time, competition between restaurants has caused food to become increasingly processed and filled with additives -- thus the reason the additives dock you valuable time in the game.
