Yes, all 3 Gila River Casino's have there own chip's now. They are not interchangeable with each other.
Lone Butte - all new chip's
Wild Horse - all new except $1. ( $1. will be out in 1 to 2 week's.)
Vee Queeva - should have all new chip's (I have not been there but should be on tables).
All previous chip's will be obsolete in November.
