Chipotle is once again giving fans a shot at free food for National Burrito Day this Thursday.
It relaunched its Burrito Vault game this morning for Rewards members in the US and Canada.
The top prize is free burritos for a year.
The game requires players to guess what is in an imaginary burrito order 'ingredient by ingredient' to open the Vault.
With over 53 ingredients and more than a billion possible combinations, it won’t be easy.
But for those who get it right, Chipotle is handing out 157,500 BOGO codes, redeemable for free food on National Burrito Day.
Other prizes include free burritos for a year and bonus rewards points — with the total prize pool valued at around $1 million.
Rewards members have until Wednesday night to play and win, and they claim prizes on Thursday.

Inspired by word puzzles, Chipotle received positive responses from fans after its Burrito Vault debut last year.
The game was played more than two million times.
Now, the fast food chain is doing more than just giving out BOGO codes to lucky customers.
'Last year, our Burrito Vault drove unprecedented fan engagement that resulted in our highest digital transaction day of all time,' said Chris Brandt, chief brand officer.
'Now, we are giving them another chance to crack the code and score more free burritos.'
Only 2,500 Chipotle Rewards members will receive a BOGO code every hour if they guess the right combination and unlock the Vault.
However, the first players who unlock it on the hour will win free burritos for a year.
Anyone who's too late to win the BOGO code will automatically receive 25 reward points in their account.
The Burrito Vault contains around $1 million worth of prizes for its Rewards members

The game comes after Chipotle was the topic of a social media frenzy.
Mayhem erupted online after Union Rayo published an article claiming Chipotle was bankrupt.
'The claim that Chipotle is closing restaurants is false,' a spokesperson told DailyMail.com.
Chipotle recently said higher menu prices had deterred budget-conscious consumers in recent months - hitting it sales.
And prices could rise more - especially if Trump's 25 percent tariff on goods from Mexico goes ahead. That would hit sales even more, the company said.
Chipotle, which has also just launched a new honey chicken flavor, was reporting its earnings for the October to December period, the first quarter with Scott Boatwright at Chipotle's helm.
