The Fort Worth City Council on Tuesday approved spending another $100,000 on outside lawyers to defend a city ordinance that regulates game rooms.
The money is in addition to $200,000 already spent by the city.
Three different owners of the machines challenged the law in court, and the cases are still pending.
The law, which passed in 2014, outlaws 8-liners and other gaming devices except in industrial districts.
The city has hired the law firm of Kelly Hart and Hallman to work on the case.
