White Castle also has a limited-time offer: get six Original Sliders for $4

COLUMBUS, Ohio, May 12, 2025 — White Castle, the pioneering fast-food hamburger chain in America and the originator of The Original Slider®, will celebrate National Slider Day on May 15 by offering customers a free Original Slider. To enjoy this delicious burger, steamed-grilled on a bed of onions, no purchase is necessary. Customers can access a digital coupon on White Castle’s website and social media platforms or input the code SLIDERDAY in the White Castle app to redeem the offer.

To elevate the celebration, White Castle is providing a new limited-time deal: get six Original Sliders for just $4. Launched on May 9, this offer reduces the price of each Original Slider to less than 67¢ and demonstrates the brand’s commitment to offering affordable options to satisfy its Cravers’ hunger.

White Castle established National Slider Day in May 2015 to commemorate the iconic Original Slider, which Time magazine hailed as the “Most Influential Burger of All Time” in 2014. Not only is the Original Slider praised for its craveable taste, but its small, 2 x 2-inch size also makes it exceptionally easy to eat, hence the nickname “Slider.”

“The creation of the Slider in 1921 was a key moment for White Castle, helping it become a widely recognized name and starting the fast-food sector,” stated Jamie Richardson, Vice President of White Castle. “We believe that a burger with such a significant impact on the food industry deserves its own day, and we can’t think of a better way to celebrate than by giving our customers a complimentary Slider.”

Since the introduction of The Original Slider over a century ago, White Castle’s Slider offerings have significantly expanded. In 1962, 41 years after its first Slider, White Castle launched its first new item which is the Cheese Slider. Today, White Castle restaurants have different Sliders, like the Bacon Cheese Slider, Chicken Ring Slider, Double Cheese Slider, and a Breakfast Slider that has a fresh cracked egg. These items are available for order all day. Most White Castles (more than two-thirds) stay open 24/7; a lot are open after midnight, so customers can enjoy the menu and great prices whenever they get a craving.

In 1987, White Castle was the first fast-food chain to sell its signature Sliders in grocery stores. Now, 38 years later, White Castle has sold over 6.6 billion Sliders in grocery stores, club stores, and convenience stores throughout the U.S. Customers can find the closest retailer at .
