Oneida Casino W. Mason is the Oneida Nation's slots-focused casino on Green Bay's west side, at 2522 W Mason St. It is one of five Oneida gaming locations around the city, and it sits a few minutes from the main Airport Drive property with its hotel and table games. It rates 3.8 from around 2,800 Google reviewers.
The useful framing is that this is the neighborhood option. If you live on the west side or are staying nearby and want slots without the bigger Airport Drive complex, it does that job. If you want live tables, poker or a hotel room, you are heading to a different Oneida address.
What's on the floor
Slots are the core of it. Oneida lists W. Mason as offering slots around the clock, and older directory listings put the floor at around 780 gaming machines. That figure is dated, so treat it as a rough guide to scale rather than a current count.
Oneida also lists a sportsbook at this location, alongside dining, a smoke shop and shuttle service.
What it does not have matters just as much. Oneida's own location list shows no live table games and no bingo at W. Mason, and the poker room that once operated here was moved to the main casino on Airport Drive some years ago. Blackjack, roulette and poker players should go straight to Airport Drive, where table games run daily from 10am to 4am. Bingo is at the Irene Moore Activity Center, also near the airport.
Dining
Oneida lists dining at W. Mason without naming the outlets on its locations page. Older listings describe a bar and grill called The Lodge serving burgers, sandwiches, pizza and baskets, with food service running later than most local kitchens. A renovation around 2014 also added a country-music-themed bar and grill. Neither has been confirmed as current for 2026, so check what is open before planning a meal around it.
Tips before you go
You must be 21 to enter the gaming floor at any Oneida casino, including W. Mason. Bring a valid government-issued photo ID. (The 18-and-over exception at Oneida applies only to bingo at the Irene Moore Activity Center.)
Hours are straightforward here. Google lists W. Mason as open 24 hours, seven days a week, and Oneida's own site says the slots are open 24/7. Dining and the sportsbook may keep shorter hours, so confirm those separately if they are the reason for your visit.
Oneida's stated policy is that smoking is permitted only in designated outdoor areas and not inside its casino, hotel or bingo hall. Expect a smoke-free floor.
Parking is on site, and Oneida lists shuttle service from this location. If you are staying at the Oneida hotel on Airport Drive, the shuttle is worth asking about rather than driving between the two.
Nearby alternatives
Oneida Casino Airport Drive is the main property, with table games, poker on select days, a sportsbook and the hotel. The Irene Moore Activity Center next door is the place for bingo. For a quick slots stop on the north-west side, Oneida One Stop Packerland runs a smaller floor with a convenience store.
