Keystone Skill LLC, doing business as Keystone Klub, operates dedicated skill game lounges across Pennsylvania, with 18 locations according to public records as of 2025. The company opened a 30-machine arcade in the Palmyra Shopping Center at 901 E. Main St. in Palmyra on August 30, 2025. Its skill games resemble casino slot machines but incorporate an element of skill required for cash payouts, distinguishing them from pure gambling devices as ruled by multiple Pennsylvania courts. The lounges serve customers in Pennsylvania, where skill games remain unregulated and untaxed. Keystone Skill is owned by North Carolinians David and Kim Eilers, who began operations in Pennsylvania in 2022 after North Carolina courts deemed their skill-based games illegal. The company is based in Scranton.
