Thats one of the best written posts I have seen and I agree with you wholeheartedly on this.
How can it be "random" if the jackpot ie
RF is determined by a central RNG.
Say you hit the deal button and the central RNG decides that this is the big jackpot it must have to deal the
RF straight in (PAT) Otherwise you may have someone discard the 3 cards of the royal and then what!!
Anyway I can only echo your words on this and think it needs to be displayed very prominently that this is a slot machine and the odds of getting any winning combinations are set by something other than a random deck of cards.
Very sorry that you lost a considerable sum of money under totally false pretenses mate.
