It's two points for every dollar you spend with Saphire, Royal and Onyx member cards.
You basically have to play $200,000 to get that 400,000 points. It takes forever to get to onyx level at 400,000 points. If you bet large and max it will eat your money.
Choctaw Casino in Durant is the biggest rip off!!! The payouts and free spins are sooo few and far in between that you basically have to play the lowest bet possible in order to just play.
