The Nacogdoches County Sheriff's office says nearly 50 people face charges. Some are due in court by Tuesday.
Authorities say Saturday night's raid of the casino trailer in a rural area resulted in confiscation of 71 so-called 8-liner gambling machines, plus as much as $15,000.
The Nacogdoches Daily Sentinel reports an exact tally could come Monday.
Investigators say eight alleged casino workers face gambling-related charges. Nearly 40 patrons were issued Class C misdemeanor gambling citations, which carry a maximum fine of $500.
Sheriff Thomas Kerss says the alleged operators were making daily bank deposits. The money trail helped lead authorities to the illegal gaming.
