Massachusetts Casinos Map
Massachusetts has three casinos, two full resorts and one slots parlor, each in a different corner of the state. This Massachusetts casinos map groups them by region: Encore Boston Harbor on the water just north of Boston, MGM Springfield in the west, and Plainridge Park down in the southeast near the Rhode Island line. All three opened in the last decade under the state’s 2011 gaming law, and the minimum age to gamble is 21 at every one.

How casinos are spread across Massachusetts
Massachusetts built its casino market deliberately and slowly, and it shows in how the three venues are spread out. The 2011 Expanded Gaming Act split the state into regions and allowed at most one resort casino in each, plus a single slots parlor, so there is no cluster anywhere. The result is one casino near Boston, one in the west, and one in the southeast, each standing alone in its part of the state.
Encore Boston Harbor is the headliner, a Wynn Resorts tower on the Mystic River at Everett, about five miles north of downtown Boston and reachable by car, water shuttle, or the Orange Line. It is the largest and busiest floor in the state. Out west, MGM Springfield anchors a stretch of downtown Springfield in the Connecticut River valley, the only casino for the entire western half of Massachusetts and a draw for the Pioneer Valley and the nearby Connecticut line.
The third is different in kind. Plainridge Park Casino at Plainville, in the southeast near the Rhode Island border, is a slots parlor attached to a harness racing track, with slot machines but no table games. A fourth casino was meant for southeastern Massachusetts under the gaming law, but that license was never awarded, which is why Cape Cod and the southeast coast have no resort casino and Plainridge stands alone in that corner.

§ Casinos by region
The hub’s routing job. Massachusetts has one venue in each of three regions, each linking down to its own page as it comes online.
Greater Boston Everett · on the Mystic River
Encore Boston Harbor is the state’s flagship, a 2.6 billion dollar Wynn Resorts property on the waterfront at Everett, five miles north of downtown Boston. It carries the largest gaming floor in Massachusetts, a single 27 story hotel tower, a large poker room, fine dining, and a harborwalk, and you can reach it by car, by water shuttle on the Mystic River, or from the Orange Line. It is the closest casino to Boston and the busiest in New England outside the Connecticut tribal resorts.
Western Massachusetts Springfield · Connecticut River valley
MGM Springfield brought a casino to downtown Springfield in 2018, woven into several blocks of the city’s South End rather than built as an isolated resort. It is the only casino in the western half of the state, serving the Pioneer Valley and pulling from just over the Connecticut line. The floor is smaller than Encore’s but it pairs gaming with a hotel, dining, and an entertainment district built into the surrounding streets.
Southeastern Massachusetts Plainville · near the Rhode Island line
Plainridge Park Casino is the outlier, the state’s only slots parlor rather than a full casino. It sits at Plainville in the southeast, close to the Rhode Island border, and pairs more than a thousand slot machines with a live harness racing track. There are no table games here by license, but it added a retail sportsbook when betting went legal. It was the first gaming venue to open in the state, in 2015, and it remains the only one in the southeast.
Casino laws and minimum age in Massachusetts
Casino gambling is legal in Massachusetts under the Expanded Gaming Act of 2011, regulated by the Massachusetts Gaming Commission. The law set a tight structure: up to three resort casinos, one each in a Greater Boston region, a western region, and a southeastern region, plus one slots parlor anywhere in the state. Two of the resort licenses went to Encore and MGM Springfield and the slots license to Plainridge Park, while the southeastern resort license was never awarded. There are no operating tribal casinos in the state, though the Mashpee Wampanoag have long pursued a separate project in Taunton.
The minimum age to gamble is 21 at all three venues, the same age that applies to sports betting and the Massachusetts Lottery. Because alcohol is served on the gaming floors, there is no 18 and over area. Retail and online sports betting have been legal since 2023, but online casino games are not legal in the state as of 2026. Hours vary by property and the floors generally run late or around the clock, so check the official site before planning around them, and confirm the current age and rules at the venue, since policies can change.

The biggest casino in Massachusetts
Encore Boston Harbor is comfortably the largest casino in the state and one of the most expensive ever built in the country at about 2.6 billion dollars. The gaming floor runs around 210,000 square feet with roughly 3,200 slot machines, about 140 table games, and a large poker room, set beneath a single 27 story hotel tower with hundreds of rooms. It sits on a reclaimed industrial site on the Mystic River at Everett, with a public harborwalk along the water. MGM Springfield is the next largest and Plainridge Park the smallest, a slots only floor. Counts shift with renovations, so the figures here are a May 2026 snapshot.
Three casinos by design
Massachusetts has exactly three gaming venues because the law was written that way. The 2011 Expanded Gaming Act capped the state at three resort casinos, one each in a Greater Boston region, a western region, and a southeastern region, plus a single slots parlor. Encore took the Boston region license, MGM took the western one, and Plainridge Park took the slots license. The southeastern resort license is the missing piece: it was held back for years while the Mashpee Wampanoag pursued their own First Light Casino in Taunton, a project tied up in federal land in trust litigation and never built. That is why the count has stayed at three and why the southeast coast and Cape Cod have no resort casino.
Sports betting in Massachusetts
Sports betting went legal in Massachusetts in 2023, both as retail sportsbooks inside the three casinos and as online and mobile apps. All of it is regulated by the Massachusetts Gaming Commission, and the minimum age is 21, the same as the casino floor. Several national books operate in the state alongside the in person sportsbooks at Encore, MGM Springfield, and Plainridge Park. Online casino games, the slots and table games some neighboring states allow on a phone, are not legal here, so for casino play you still have to visit one of the three venues in person.
