The nearest documented casino sits 2.4 straight-line miles from Boston's center
The closest documented casino to Boston is Encore, at 2.4 miles straight-line from the city's coordinate point. That figure is a great-circle measurement, not a road distance. If you are asking about playing keno near the Copley Marriott, the first thing to understand is that no venue in the documented set is measured from the hotel itself; every distance below is measured from Boston's fixed coordinate, and your hotel adds a short local leg on top of that.
Road distance is always longer than straight-line distance. This article does not publish driving mileage, driving time, transit time, or any route instruction. What it can do is give you the fixed geographic picture: which documented venues exist, where they sit relative to Boston, and how far each one is as the crow flies.
Keno availability is a separate question from venue location. A venue being close to Boston does not, by itself, tell you whether keno is offered inside it. Keno is a lottery-style game that may be offered in some Massachusetts and New Hampshire venues and not in others, and the game lineup at any property changes. The distance table below answers the geography question; the keno question has to be confirmed with the venue itself before you travel.
Documented straight-line distances from Boston
Every figure in this table is a great-circle distance from Boston's documented coordinate. None of these numbers is a driving distance. Use them to understand relative proximity, not to plan a route.

| Plainridge | 25.8 | great-circle |
| Gate City | 33.9 | great-circle |
| Twin River | 38.3 | great-circle |
| Filotimo | 45.6 | great-circle |
| Foxwoods | 76.8 | great-circle |
| Mohegan Sun | 80.1 | great-circle |

The documented set contains 318 venues measured to Boston. That number is not a census of every casino in the region; it is simply how many venues this file records with a measured distance to the city. For a complete current list of licensed venues, the Massachusetts Gaming Commission and the New Hampshire Lottery Commission are the authoritative channels.
Why straight-line distance understates the real trip
A great-circle line ignores everything that stands between you and a venue. Boston sits on a harbor, with the Mystic River, the Charles River, and Massachusetts Bay shaping how roads have to run. Encore, for example, sits across the Mystic River in Everett; the straight-line figure crosses water, while any road route has to find a bridge or tunnel crossing.
Road networks do not follow straight lines. They bend around water, rail yards, protected land, and dense urban blocks. A venue that is 2.4 miles away as the crow flies can require a substantially longer road trip because the street grid forces a loop rather than a direct line.
State borders add another layer. Several documented venues sit outside Massachusetts: Gate City and Filotimo are in New Hampshire, Twin River is in Rhode Island, and Foxwoods and Mohegan Sun are in Connecticut. Crossing a state line does not change the straight-line math, but it can change the road route, the traffic pattern, and the regulatory environment around the game you are looking for.
Where each documented venue sits relative to Boston
Encore is the closest documented venue, at 2.4 straight-line miles. It sits in Everett, Massachusetts, just north of Boston across the Mystic River. Its documented coordinate places it slightly north and slightly west of Boston's center point.
Plainridge sits in Plainville, Massachusetts, at 25.8 straight-line miles. That puts it to the south and west of Boston, well outside the immediate metro core. Gate City sits in Nashua, New Hampshire, at 33.9 straight-line miles, north and west of Boston. Twin River is in Lincoln, Rhode Island, at 38.3 straight-line miles to the south and west.
Filotimo sits in Manchester, New Hampshire, at 45.6 straight-line miles, north of Boston. Foxwoods and Mohegan Sun sit in Connecticut at 76.8 and 80.1 straight-line miles respectively, to the south and west. MGM Springfield is in Springfield, Massachusetts, at 80.3 straight-line miles, far to the west. Oxford is the farthest documented venue in this set, at 125.1 straight-line miles.
Your position is not fixed; the venue's is
The query asks about a hotel near Copley Square, but no distance in the documented set is measured from the Copley Marriott. Every figure above is measured from Boston's single fixed coordinate. The hotel is inside Boston, so the straight-line distance from the hotel to any venue will differ from the city-level figure by some amount, but this article cannot measure that hotel-specific pair because the hotel's coordinate is not in the documented set.
The venue's position is fixed and documented. Your position is whatever it is, and the way to get a hotel-specific measurement is to take the venue's documented coordinate and measure from your own starting point using any mapping tool. The venue coordinates are public and stable; your starting point is the variable.
If the specific pair you care about is not in the table above, this article cannot state that distance. The pairs that are documented are the ten rows shown. For any other starting point, measure from the venue's fixed coordinate yourself.
What to confirm before you go
Keno availability is the single most important thing to confirm, because this article cannot tell you which documented venue currently offers keno. Call or check the venue's own website before you commit to a trip. A venue may have keno today and not next month, or may offer it only in certain areas of the floor.
Confirm the road route and parking situation from your actual starting point, not from Boston's center. The straight-line table tells you which venues are geographically close; it does not tell you which is quickest to reach from the Copley Marriott. Road distance, traffic, and parking all vary by time of day and by your exact starting address.
Confirm the venue's current operating status and any entry requirements. Nothing in this article documents opening hours, admission policies, or current game schedules. The venue's own published channels are the only place those live.
FAQ
Does Encore Boston Harbor offer keno?
This article does not document keno availability at Encore or any other venue. Encore is the closest documented casino to Boston at 2.4 straight-line miles, but proximity says nothing about which games are on the floor. Keno is a lottery-style game that may or may not be offered at a given Massachusetts venue, and game lineups change. Confirm directly with the venue before travelling.
How far is the nearest casino from the Copley Marriott?
The documented set does not include a distance measured from the Copley Marriott itself. The nearest documented venue to Boston's center is Encore at 2.4 straight-line miles. The hotel sits inside Boston, so its distance to Encore will be close to but not identical to that figure. Road distance is longer than straight-line distance in every case.
Which documented casino is closest to Boston for keno?
Closest by straight-line distance is Encore at 2.4 miles, followed by Plainridge at 25.8 miles. But closeness does not indicate keno availability. The article cannot rank venues by game offering or recommend one over another. Check each venue's current game list directly, and treat the distance table as a geographic reference only.
