A common feature in slot machines is wilds, which can substitute for all other symbols except scatters to create a winning combination. They can also appear randomly on the reels.

Another common feature is a jackpot, which can be won when all the symbols on a pay line match up and the number of credits paid out equals or exceeds the total amount of the player’s wager. These jackpots can be won during normal play or in special rounds called bonus games, which are usually triggered by certain combinations of symbols on the pay table.

In addition to a pay table, a slot machine has a help menu that lists the rules of play and instructions on special features. It also contains a help button that will display an explanation of how to use each feature. It is important to read the information on these screens thoroughly before playing the game, as it can make all the difference between a successful session and a losing one.
