400 Horses Casino Brings New Tribal Gaming Space to Polson

The new 400 Horses Casino is located on a 79-acre tribal land parcel, with approximately 10 acres of that tract leased for the casino project. The land was incorporated into the city of Polson in 2023, which allows the casino to connect to municipal water and sewer systems instead of relying on a private well or septic drain field.

Construction kicked off on April 9, 2025, after final project plans received approval in late 2024. The development has been in motion since 2021, operated under the enterprise structure of the Confederated Salish and Kootenai Tribes.

Inside the venue, S&K Gaming will offer Class II slot machines and electronic table games. Live table games are not planned for the casino’s launch. The casino will open with more than 300 gaming machines, and an additional 100 machines are expected to be added later.

The property also includes 371 Bar and Grill, a 70-seat restaurant with both indoor and patio dining that overlooks Flathead Lake. Chef Pedro Vera, former executive chef at Finley Point Grill, will lead the restaurant’s kitchen. The restaurant will keep extended hours that align with the casino’s operating schedule.

S&K Gaming designed the new site to fix layout problems at Kwataqnuk Resort & Casino, where gaming areas were added after the hotel was originally constructed. The company also drew on experience from Gray Wolf Peak Casino to create a more efficient floor plan for the new location.

Traffic improvements around the site are still part of the full project. S&K Gaming has partnered with the Montana Department of Transportation on road realignment and new turn lanes, though some upgrades may be completed after the casino opens.

The name 400 Horses came from community input and honors Chief Alexander, a central leader in the formation of the Confederated Salish and Kootenai Tribes. Chief Alexander, also known as No Horses, was reported to own roughly 400 horses in the later years of his life.

After the Polson casino opens, S&K Gaming plans to renovate Kwataqnuk Resort, with a focus on updating the property to be more family friendly.
