With penny slots, all the player needs to do is enter their money into the machine and hit a button. Enter the money in the machine, select your lines or bet size, hit the button, and hope for the best. There is no thinking or decision-making involved like in blackjack, sports betting, poker, and so on.

Penny slots function just like traditional slots  put in a penny and hit a button (or pull a lever) to spin the reels. End up with the right combination and you could win HUGE.
