How to get a free Whopper at Burger King

To get a free Whopper at Burger King, you must be a member of the Royal Perks loyalty program. You can join on the website or in the BK app.

Then, you must propose a new Whopper in the Million Dollar Whopper Contest, which runs through March 17.

Originally, Burger King was giving contest participants a free Whopper with $1 purchase. Now, the fast-food chain will give anyone who participates a coupon for a free Whopper (no purchase required) in their account after submitting their initial entry.

You don't have to purchase anything to enter the contest, but it's only open to legal U.S. residents 18 years or older.
