I would definitely choose to receive money, I say that because if I received a free spin I would keep playing and lose everything, so it wouldn't make any sense to choose a free spin when in the end I would still lose, in games that rely on luck we can never be confident of that we are going to win and we will make a profit, this is an illusion and mistake that we should not make at all, free spins encourage the person to play more and consequently the person will lose, I prefer the money, at least I will be able to do something other than play , because the game money I separate just to play, the bonus money and to do other things
I think I would prefer direct cash as incentive although in my opinion most gamblers would prefer other option, as it would increase their chances. I think giving gamblers option to play games for free is literally the best incentive they can give. Gambler's mind is wired think that its best feeling to make money with unpaid game. But some gamblers like me may be just more into rewards than the game itself.
the saddest part is that most people who choose free spins are confident that they will win the game. but they lose and get frustrated, but still they keep playing and losing, this is a cycle of many continuous losses, games that depend on luck always in the end just make the person lose
As mentioned earlier each one has its own set of advantages and disadvantages. There is no right answer; they're both great options. With that said, I prefer bonus credits. I can always spend that bonus money on slots if I want to.
I really can't see how receiving money would be a disadvantage? the person with money can spend on other things that are not related to games, for games the person already has money to play. even because if the person creates an account at the casino and because they have separate money to play
