Denny’s rewards program features fun challenges, tracking mechanism

If you haven't checked out Denny's rewards program it's been refreshed with perks as well as personalized challenges for unlocking rewards.

Members, who can join either at Dennys.com or via the brand's app, are provided a digital wallet that holds offers and tracks rewards for redemption.

Personalized challenges allow for any type of dining experience: dine-in, take-out or delivery. The rewards program features new challenges and rewards each month.

One rewards aspect that hasn't changed is that members get a free breakfast on their birthday.
