Papa John's is hosting a fun Super Bowl promotion.

The pizza chain is asking customers to join its rewards program and guess the Super Bowl coin toss. If the majority of rewards members guess correctly, every member will receive a coupon for a free large one-topping pizza and a 2-liter Pepsi Max.

In order to sign up for the program, visit freepapajohns.com. You will be asked to enroll in the program, watch a video and "call the coin toss."

The results of the Papa John's coin toss will be announced on Feb. 2, but customers can continue to sign up for the rewards program to be eligible for the freebie through 6 p.m. Feb. 5.
