For Gambling, I can choose other games as well. There are a bunch of popular games that I can try without actually knowing how it works. I remember I started playing slots without knowing how it pays.
There might be many gamblers who don't know how it works but like to wager over particular slot so it doesn't matter a lot because we just want to see how much lucky we are in that bet or say in gambling.You just pick a slot like when we try new one we don't have idea about it but when we start playing we know about it and build a taste for them.But all is dependent on luck in these slot based games.
