That's news to me. I didn't think craps & roulette was within the scope of games approved by Prop 1A.

The text below comes from a website that promoted Prop 1A at the time -- www.Prop1A.net. Note the section in red. It doesn't seem to include craps or roulette:

Prop 1A implements California’s Tribal-State Compacts for Indian Gaming

Limited gaming allowed on tribal lands — California Indian tribes will be allowed to continue limited gaming at

Indian casinos on federally-designated reservation lands. Permitted games include slot machines, house-banked card

games, lottery games and parimutuel wagering.

Revenues shared with non-gaming tribes — Revenues from Indian gaming must be shared with non-gaming tribes

to support education, health care, housing and economic development programs on reservations that don’t have

casinos.

Protections for local communities and the environment — For any significant new construction related to an

Indian casino, a tribe must prepare an environmental report on any potential impacts to areas outside the reservation,

allow the public to comment on the report and make good faith efforts to mitigate any impacts.

Strict regulation — Indian gaming is strictly regulated. In addition to direct regulation by tribal governments and

federal government agencies including the National Indian Gaming Commission, the Department of Justice, the FBI,

the IRS and the Department of the Interior, the compact provides for new oversight by the state.

Limits on the number of casinos and slot machines — Although most California tribes are located in remote areas

where a casino is not practical or where market conditions will only support a small gaming facility, the compacts also

set certain legal limits. Specifically, no reservation will be allowed to have more than two gaming facilities or more than

two thousand slot machines.

Revenues shared with state and local governments — Gaming tribes will pay a percentage of their revenues to

state and local governments, using a sliding scale (ranging from 7% to 13%) based on the number of gaming

machines they operate. These funds will be dedicated to support local programs and services in nearby communities,

and to reimburse state and local agencies for their costs to regulate Indian casinos.

Employees have option to join labor unions — Employees working in most non-management jobs at Indian

casinos will be allowed to join labor unions if they choose to do so.

Standard minimum ages for patrons — The minimum age for a patron at an Indian casino will be 21 in any area

where alcohol is served. In areas where no alcohol is served, the minimum age will be 18, the same as for the state

lottery.

Agreement valid for 20 years — The terms of the compact will be valid for 20 years with the option to extend.

Changes may be re-negotiated after three years, but must be jointly agreed to by both the tribes and state, and

approved by the federal government.
