I guess you are right because I just won some nice amount of RP again.
As I said in my previous post, nothing has changed.
You won reward points in those three spins, just because you rolled numbers lower than 332,308,319.
Every time you spin the wheel, some mathematical calculations are done and you get a random number.
You get 50 RP, if you hit a number between 0 and 329,308,319, you get 500 RP if you hit number between 329,308,320 and 331,308,319 and you get 5000 RP if you hit a number between 331,308,320 and 332,308,319.
