Chipotle Will Give 20 People Free Burritos Until 2033

Chipotle Mexican Grill turns 20 this Saturday. The popular food chain will celebrate its anniversary by kicking off a 20-day-long treasure hunt, "Adventurrito," that offers a 'burritoful' grand prize of 20 years of free burritos (approximate retail value: $9,100, in constant dollars.)

Every day at 10:20 p.m. ET for the first 19 days, Chipotle will release a trivia question on Adventurrito.com, and players will be entered to win free burritos for one year (that's one burrito a week for 52 weeks). Twenty winners will be chosen at random each day. On the twentieth day, Chipotle will release a final puzzle, and the first 20 players with the highest scores will be awarded free burritos until 2033.
