During the late 1990s, then-Governor George Pataki signed an agreement granting the Seneca Nation of New York the right to acquire and build three full-scale casino gaming operations. The three casinos (Seneca Niagara Casino in Niagara Falls, Seneca Allegany Casino in Salamanca and the controversial Seneca Buffalo Creek Casino in Buffalo) are the only casinos that operate over all of Western New York as part of the agreement, for which the Senecas pay a portion of revenues to the state of New York (which, in turn, returns part of that money to the host municipalities). Twice over the course of the compact's history have the Senecas stopped paying their exclusivity payments: once in a dispute over whether video lottery terminals constituted the breach of the agreement, and again in 2017 after the Senecas claimed they are no longer required to pay the exclusivity payments but still maintain exclusivity under the language of the agreement.
