Most of the time if you really want to see what a real slot is like, and if you will like it or not, drop it to minimum you could gamble and play 10k rounds if you can, obviously sometimes it is too high and you can't play it, but if you can afford to you should do that because under 1k
I think I can get a clear opinion on wether I like the slots or not simply from testing the bonus feature without having to play 10k rounds. What matters the most for me would be the bonus feature, I personally dont really care about the base game at all because I tend to either use the turbo mode or do another stuff while I roll
Even if you are a fan of the base game, simply look for the slot review videos on youtube instead of rolling 10k rounds.
I think you can understand if you like it or not, but you do not really understand if you would have a strong feeling or not, there are tons of things that start with dislike that eventually turns into love if you give it enough time, or you will just turn the dislike into hatred as well.
I mean everyone is free to do whatever they want, that is the beauty of gambling, there is no way of gambling as long as you do not lose more than you can afford, I have lost way too much money overtime just because I was being silly, I haven't in years but I know what I am doing now and I can say that if you just deposit small amount to never bother you, that means you can gamble whatever way you want to gamble and you will have fun because you are playing however you want. I usually end up gambling as much as I can afford on a new game to figure out if I want to, but if you get it in 100 bets, then you do you.
