What Is a Slot?

A narrow opening, especially one for receiving something, as in a machine or container. Also, a position, time, or place for an event or activity: She slotted the appointment into her calendar.

You checked in on time, made it through security, got to the gate, waited in line and finally found your seat. Then you hear the captain say, “We’re waiting for a slot.” What is a slot and why can’t we take off?

In the past, a casino’s slot area was the main attraction, with machines all around the casino floor. Then came digital technology and the introduction of touch-screens as a way to interact with the machines. These new slots could feature more paylines, a bigger number of winning combinations, and special features like progressive jackpots.

Whenever you sit down at a slot machine, test the payout percentages by putting in a few dollars and seeing how much money you get back. If you’re spending more than you’re earning, move on. In the same vein, avoid slots near promotions lines or the entrance to a casino as they may have lower payouts in order to draw players away from other gambling areas. It’s also a good idea to avoid slots next to gaming table areas, as they’re often targeted at people looking for a quick win.
