Billdle is a free daily guessing game about the strangest prices in America: real U.S. medical bills. Each day everyone gets the same bill — an MRI, an emergency room visit, an ambulance ride, a hospital birth — and six guesses to land within 10% of the real price. Every wrong guess reveals another line item and tells you whether the answer is higher or lower.
Every price is real. Answers come from published national data and from the machine-readable price files that every U.S. hospital is federally required to publish under hospital price transparency rules — files most patients never see. Playing Billdle is a surprisingly effective crash course in what healthcare actually costs, what insurers really pay, and why the same scan can cost 10× more across town.
