The amount of credits or money available for playing a slot machine. Typically displayed in the form of a graphic on the machine, this display can indicate the amount currently earned and any bonus rounds that are active. It may also list the regular symbols and their payouts. Slots are often themed, with the types of symbols and bonus features aligning to the theme. In addition, many slots feature multiple paylines. These lines, which may run horizontally or vertically, determine the winning combinations. In some cases, a player can earn additional rewards, such as free spins or multipliers, by landing certain combinations in the bonus round. These bonuses can add up quickly and significantly increase a player’s bankroll, allowing them to continue to play for larger sums of money. These bonuses often use a different set of reels, and are often more complex than the regular game. They can also include a progressive jackpot, where the amount of money that can be won increases with each spin of the reels.
