A slot is a narrow opening, notch, or groove into which something can be put. It is the term used in computers for a place where one can fit an expansion card that adds some specialized capability to a computer system.
The term is also used to describe the narrow openings in aircraft wingtips that allow an airfoil to maintain a smooth flow of air over its wings. A similar opening is used in some bird species to help them maintain a stable flight path during flight.
Slots are used in aviation for many purposes, including limiting the number of aircraft that can take off and land at an airport at any given time. They are based on the principle that the number of aircraft in the air is related to traffic, so restricting them can make it easier for airlines to handle their operations at the airport.

Some slot machines have a special feature known as ’tilt’ that makes or breaks the game’s outcome when a switch on the machine is tilted out of position or tampered with in some way. This feature was introduced in electromechanical slot machines and is no longer in use on most modern machines.
The first fully electromechanical slot machine was produced in 1963 and named Money Honey by Bally. It was the first slot machine to have a bottomless hopper, which meant that it could automatically payout coins without requiring an attendant’s help.
Slots are often considered to be a form of gambling that can be addictive, particularly in the United States. A 2011 60 Minutes report cited psychological research showing that players of video slots develop gambling addictions at a much faster rate than those who play traditional casino games.
