You have until the end of the month to score yourself some free Guacamole from Chipotle. According to Food and Wine, all you have to do is head over to Guac Hunter and play the game on the website.

If you make it through three rounds of the game, which asks you to "spot the five differences in each photoset before time runs out," then you'll win some free guacamole! Of course, even if you don't win the game, you'll still get a prize!

Go try the game right away to see how well you can do! Were you able to beat it?
