What Is a Slot?


A slot is a narrow opening, often in something with multiple parts. For example, a mail slot in a mailbox or a time slot on a calendar. The word is probably from the verb to slot, meaning to place something into a narrow opening or hole. It may also refer to an allocated, scheduled time for an aircraft to take off or land, as authorized by an airport or air-traffic authority. The International Air Transport Association holds a Slot Conference twice a year to allow airlines to secure slots that coordinate their routes and optimize flight schedules.

The number of pay lines in a slot game is one of its most important features. These lines, known as winning payouts, are where a player will earn a prize if they land matching symbols on them. Typically, a slot’s pay table will have an image of each symbol and how much players can win for landing three, four or five of them on a pay line. The pay table will also include information on any special symbols in the slot, such as Scatter or Bonus symbols.

A progressive jackpot is a large jackpot that increases incrementally as players play the game. These jackpots are often displayed in a prominent location on the machine and can be extremely large. Progressive jackpots can be life changing and are a great incentive for players to play a slot.
