Sprockets Fun Foundry

221 Swanzey St · Keystone, SD

Why you should go…

Sprockets Fun Foundry is a multi-level indoor entertainment center just off the Keystone boardwalk, a few miles from Mount Rushmore, housed in a building styled as an old mine with rusty metal, barn wood and artifacts from the Homestake Gold Mine. Visitors ride virtual reality attractions with wind, heat and moving floors, play a 50-plus game arcade on digital fun cards, and bowl on four duckpin lanes with small pins and hand-sized balls. A second-floor taproom serves craft beer, local wine, pizza and wings. The venue is run by the owners of Rushmore Cave and Rush Mountain Adventure Park; it is open year-round, with Thursday to Sunday hours in fall and winter. Look for the giant robot sign out front.

Good to know

General attractions guidance

Habits that pay off across this whole category, not rules for this one venue. Always check the official site for the specifics.

  • Book the time slot, not just the ticket

    Timed entry is now the norm at big-draw attractions, and online tickets are often cheaper than the gate.

  • Grab the daily schedule on arrival

    Feeding times, keeper talks, and shows run on a posted timetable that changes day to day.

  • The first hour is the quietest

    Queues build through late morning and peak after lunch, so an early start buys you the shortest waits.

  • Budget past the ticket price

    Parking, lockers, strollers, and food inside the gates are common extras worth planning for.
