Chipotle (CMG) is celebrating National Burrito Day with a special offer for customers that will not only fulfill their craving but will also fill their digital wallets with some cryptocurrency.

The Mexican grill is giving away 10,000 burritos for free on April 1 in addition to up to $100,000 in Bitcoin to several lucky winners.

The contest gives a nod to Stefan Thomas, the founder and CEO of Coil, who, along with Chipotle, launched the new interactive game Burritos or Bitcoin. Thomas is known for losing his hard drive login, which stored $387 million in Bitcoin, and is now urging fans to carry out a mock “chiptocurrency” rescue mission to uncover the digital wallet login.

While Chipotle customers will not log into Thomas’s actual hard drive, they will have the chance to crack the code on the Burritos to Bitcoin game for their chance to win up to $25,000 in the cryptocurrency.

To play, each customer will have 10 tries to guess a valid six-digit code that will win them a free burrito, $500 in Bitcoin, or up to $25,000 in Bitcoin. If a player does not guess the right code in their 10 attempts, they may still win a special offer from Chipotle, the chain said.

The odds of winning a prize break down to a total of 10,000 fans receiving a free burrito, 50 players winning $500 in Bitcoin, and three customers winning $25,000 in Bitcoin, Chipotle said.

The Burritos or Bitcoin offer goes live on Thursday at 9 a.m. PDT and ends at 6 p.m. PDT the same day at burritosorbitcoin.com.

No purchase is necessary to play, but participants must be at least 18 years old and a legal resident of the U.S. Bitcoin rates will be determined as of Thursday at the cut-off time, the company’s rules state.

“National Burrito Day is a huge moment for Chipotle as our fans traditionally flock to our restaurants and digital platforms to order their favorites,” Chris Brandt, chief marketing officer at Chipotle, said in a statement. “We're always looking for unique ways to enhance the celebration, and this year, we're giving fans the opportunity to acquire two highly valuable assets: Burritos or Bitcoin.”

The giveaway marks Chipotles entrance into the cryptocurrency market as one of the first U.S. restaurant chains to offer such a promotion.

In recent months, several companies have allowed cryptocurrency to be used as a form of payment at their businesses, with PayPal announcing on Tuesday that it was rolling it out for purchases on its platform in the U.S.

Tesla allows for purchases of its electric cars with Bitcoin, and several retailers allow for payments with Dogecoin, including luxury hotel group The Kessler Collection.

Shares of Chipotle were trading at $1,417.35 as of 12:19 p.m. EDT on Tuesday, down $7.26 or 0.51%.
