Gaming Regions and Tribal Priority Rights: How Massachusetts Region C Works
States sometimes divide their territory into gaming regions and set one aside for a tribe. Here is how that design works and where it can be tested.
Some states do not leave casino siting to chance. They divide the map into gaming regions, decide how many licenses each region can have and, in some cases, reserve a region for a tribe. Gaming regions and tribal priority rights are a form of geographic exclusivity, and Massachusetts offers a current example in Region C, the southeastern part of the state covered by the Mashpee Wampanoag Tribe's compact. This explainer sets out how the design works and where it can come under pressure.
What a gaming region is
A gaming region is a state-defined area within which gaming licenses or compacts are allocated. The Massachusetts Expanded Gaming Act divided the Commonwealth into three regions: Region A around greater Boston, Region B in the western part of the state and Region C in the southeast. The idea was to spread casino development geographically, avoid saturating a single market and let each region be evaluated on its own economics. Commercial licenses were awarded in Regions A and B, and the Mashpee Wampanoag Tribe's rights in Region C are described in its tribal-state compact.
Regional design serves several policy goals at once. It controls the number of facilities, directs economic development toward particular areas and gives each host community a defined role. For tribes, it can also provide a degree of protection from cannibalization by nearby non-tribal operations.
How priority rights fit into the Indian Gaming Regulatory Act
Under the Indian Gaming Regulatory Act, Class III gaming such as slot machines and casino table games is lawful on Indian lands only where the state permits that gaming for any purpose and the tribe and state have entered a compact. Our Legal Guide walks through that structure. A compact then sets the terms: which games are authorized, how the facility is regulated, what payments flow to the state or localities, and what protections the tribe receives in return.
A tribe's priority in a region is generally a matter of state law and compact text working together. The state law may reserve the region, or a license in it, for a tribe for a period, and the compact may recognize the tribe's rights there. The Mashpee Wampanoag Tribe describes its compact as a formal agreement between two governments, negotiated under federal and state law, for tribal gaming in southeastern Massachusetts, and says it opened First Light in Taunton as its first step toward tribal gaming in the region. Details of the build-out are in our report on the First Light permanent resort.
Priority is not the same as exclusivity
It is easy to blur these ideas. A priority right says the tribe has first claim on a region. Exclusivity is a stronger promise: that the state will not authorize competing forms of gaming, usually with consequences such as reduced or suspended payments if it does. Compacts that include exclusivity typically define the protected games and the geographic area, and sometimes tie remedies to specific triggers. Our explainer on how tribal gaming exclusivity works covers the mechanics, and the piece on scope of games in a compact explains why the definition of a protected game matters so much.
That distinction is at the center of the current Massachusetts debate. In a July statement about House-passed language on historic horse racing machines, the tribe cited its rights in Region C and argued that the machines would sit outside the compact and the Expanded Gaming Act. The statement does not, on its face, assert a formal exclusivity clause. Whether the compact's text gives the tribe a remedy would depend on how it defines protected gaming and what triggers it contains. For the political and legal context, see our analysis of the Massachusetts horse racing bill.
Where regional designs get tested
Regional schemes face predictable stress points. New technologies can blur the line between categories of games, as when electronic terminals tied to horse race results resemble slot machines. Neighboring states can authorize facilities near a border. Legislatures can add gaming provisions to unrelated bills late in a session. And the passage of time can change the economics of a region that looked different when the framework was designed.
Tribes and states usually address these risks in the compact itself, through definitions, notice and consultation provisions, and dispute resolution clauses. Others rely on the political relationship alone, which can be adequate until a conflict arises.
Why it matters beyond one state
The Massachusetts structure is one of several designs in use across the country, and it differs from compacts that grant a tribe exclusivity statewide or in a defined zone. Readers comparing approaches can browse state-by-state background in the tribal gaming directory. The central lesson is that the strength of a tribe's regional position depends less on labels such as priority or exclusivity than on the specific words of the statute and the compact, and on the willingness of the state to honor them.
