Review for Thunder Valley Casino Resort Review For Thunder Valley Casino Resort Google User Apr 25 '17 at 12:33 I like Thunder Valley. The variety of slots are great. The staff is very nice and helpful. The bathrooms are always clean. I do believe you need more people to walk around for drinks. I don't know how many times I have wished I had something to drink but no one around. I like the comps I get and the free play every week. For some reason I don't get the free gifts as my boyfriend and his mother get every week and we go(my boyfriend and i) at the same time. I do enjoy Thunder Valley when I go, but haven't been winning recently, think they tightened up the machines. View full site to comment or like
