As for how to play it, it's like with any other slot, you don't need to know anything, just push the button, and anything that follows entirely depends on luck.
Yes, that is generally how slot games work. To play a slot game, you typically select your bet amount, press the spin button, and then the reels will spin. The combination of symbols that land on the reels will determine whether you win or lose.
I'm always confused when I hear someone claim to follow some techniques or strategies while they play slots. Slots are games of chance, and the outcome of each spin is determined by a random number generator. There are not strategies that will increase your chances of winning.
