I think that slots are way better than dice because of their payout structure. Lets say you are hunting 99x in dice, in this hunt you will not get paid if you hit 98x. But in slots things are different and you will get paid for every hit though you are aiming for jackpot.
I know that most of the slots pay like 80-92% of what goes into slots but still if you compare it with dice (specially hit and run method) it is more profitable in long run (although in long run you will eventually loose in both games because of house edge)
I want you to ponder upon this and please tell me how much I am right in this line of reasoning.
