What Is a Slot?

A narrow notch, groove or opening in something, such as a keyway in machinery, a slit for a coin in a machine or a time slot in a schedule. Also:

A time or place for an aircraft to take off or land as authorized by an airport or air-traffic control authority. (See also slat1.)

In computer engineering, a slot is the operation issue and data path hardware surrounding a set of one or more execution units (also called a functional unit). The concept of a slot is common in very long instruction word (VLIW) computers where the relationship between operations in an instruction and the pipeline to execute it is explicit. A slot is also the name of a unit in the x86 architecture that performs this function, although it is now often referred to simply as a pipeline.

Always check the pay table of a slot machine before you play it. The pay table will tell you how much you can win for landing various combinations of symbols, including the Wild symbol (which works like a Scatter in some games) and any Bonus or Scatter symbols. You will also find information about the game’s bonus round and any other special features. A good tip is to watch for machines that have recently paid out large amounts. Many players believe that a machine will “go cold” after a big payout, so they leave and miss out on the chance to play it while it’s hot.
