The latest numbers from the Arizona Department of Gaming show that tribal casinos contributed $40 million to the state during the first quarter of the fiscal year that began in July.
The state said that is a 192% contribution increase over the same time frame last year.
Officials said part of the interview is due to the new tribal gaming compact crafted by the legislature, governor, and representatives from many of the state's tribes.
Arizona tribes operate 24 casinos in the state.
The revenue does not reflect sports gambling which became legal in Arizona earlier in September.
