How have tribal councils invested monies from casinos into their communities? They have purchased new lands to expand the size of reservations.

Native American gambling comprises casinos, bingo halls, and other gambling operations on Indian reservations or other tribal land in the United States. Because these areas have tribal sovereignty, states have limited ability to forbid gambling there, as codified by the Indian Gaming Regulatory Act of 1988. As of 2011, there were 460 gambling operations run by 240 tribes, with a total annual revenue of $27 billion.
