Tucked up Gregory Street just inside the Black Hawk city limits, Red Dolly Casino is a friendly, old‑school stop with a loyal local following. Opened on May 18, 1992, it’s proudly billed as the oldest casino in town and keeps things simple: a compact floor of slots and video poker, a welcoming staff that knows regulars by name, and easy, free parking right beside the building. Head upstairs for comfort‑food favorites—the Dolly is famous for its value‑priced prime rib—then drop back down to try your luck on classic and newer machines. Daily hours run 8am to 2am (or later), making it an easy add to a Black Hawk or Central City casino crawl without the crowds of Main Street.
