I am just back from a quick trip to Yuma, AZ area and the just opened New Cocopah Casino. The new casino replaced the Old Cocopah Casino which was slots only. The New Casino is in a new building just South of the Old Casino (now closed), quite nice looking, has slots and table games. See scan of chips below. I have traders available. No $1 chips used, they use slot tokens on the tables.
Slots are TITO but TITO not running yet on most machines. They have a slot club.
I also stopped at Paradise Casino AZ & CA, not much new except all table games have been moved to the CA side. Both CA & AZ casinos are using some TITOs, but you can not move a TITO from CA to AZ or AZ to CA.
