Review for Thunder Valley Casino Resort Review For Thunder Valley Casino Resort Google User Jun 25 '16 at 8:49 I went with my mother in law who is a regular at thunder valley. So dinner was 50% off with her thunder valley card. She recently participated in the tournament and also won $1000 in free play. I have won in thunder valley before as well. I like their black jack tables. I love their restaurants. Their hotel rooms are lovely. Always clean. It is a great place to stay! View full site to comment or like
