The way wild cards are used is that they act as an all-purpose card that can match with any other icons on the machine except bonus icons. Wild Cards are special cards that are indicated by the word “Wild” somewhere on their icons.
There are 4 different types of icons that affect how many credits a player receives or modify how you get a winning payout. These are the icons that you see on the machines that need to match in order to get a winning payout. The main feature that affects the value of a pay line and determines the difference in machine themes are slot types. However, the amount of credits that you win or the chances of getting a jackpot will ultimately depend on whether or not you’re lucky. Since the game tries to revolve the uniqueness of a machine around the difference in wild cards and bonus icons, there will be some machines that tend to get the rewards from those bonuses a lot more frequently. When choosing the right machine to play, you want one that gives a lot of bonuses or wild cards.
