Slot machines are a form of gambling that uses rotating mechanical reels. They are activated with a lever or push button and the player can wager money. The odds of winning are determined by the symbols on the machine and number of coins wagered per spin.

Some video Demo Slot have bonus games that increase the chance of winning when a player wagers a larger amount of money. Those bonus features are often aligned with the theme of the game. A popular feature is the hold and spin function, which lets players re-spin the reels multiple times until a special symbol is landed. This can lead to big payouts.

Depending on the manufacturer, some video slots may have interactive elements, such as a hopper or reels that move as the player spins. Pay tables usually appear on the machine’s face or in the help menu. These pay tables list credits earned if the desired symbols land.
