Get Free White Castle Slider on National Slider Day

White Castle will reward its customers with an offer for a free Slider of their choice on National Slider Day May 15. Members of Craver Nation, White Castle’s customer loyalty program, will receive the offer through the White Castle app (Google Play Store, Apple App Store). No purchase is necessary to get your free slider.

White Castle introduced National Slider Day in May 2015 to honor the iconic, steamed-grilled-on-a-bed-of-onions hamburger. Apparently in 2014 , Time magazine called it “the most influential burger of all time.”

White Castle expects to give away tens of thousands of Sliders at its more than 360 Castles. In addition, White Castle will offer a buy-one, get-one-free deal for Combo #1 by delivery only. Customers can order directly from Uber Eats or Grubhub.
