If you're a Burger King buff, you don't have to wait until St. Patrick's Day to get lucky.

Between now and then, members of Burger King's Royal Perks loyalty program can get a free Whopper by entering the fast-food chain's “Million Dollar Whopper Contest.”

Last month, Burger King launched the contest giving contestants a chance to create a new custom Whopper sandwich with new toppings and, if their suggestion is chosen, they win $1 million. A bonus: The winning creation will sold at Burger King restaurants nationwide for a limited time.

OK, there are already more than 200,000 ways to customize a Whopper, according to Burger King.

"But if you’ve ever wanted to top the flavorful burger with savory sensations or sweet and sour showstoppers, then your moment to shine has officially arrived,” Burger King’s website reads.

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.
