A slot is a narrow opening or groove. It can also refer to a time slot in a schedule or plan, or the place where an activity will take place. For example, a patient can book an appointment for a health check with a doctor in a specific time slot.

The high slot is one of the prime positions for a defenseman in ice hockey. This spot allows them to rip a blistering slap shot that can be difficult for goalies to stop. In addition, a well-placed one-timer from the high slot can help a team score a shorthanded goal.

In computer technology, a slot is a narrow opening in a motherboard that holds an expansion card. These cards add functionality to a computer by providing specialized circuitry, such as video acceleration or audio control. Almost all desktop computers include a set of slots that allow users to upgrade their hardware capabilities over time.

Online slots can be played for free or with real money. Some sites offer video results to show the reels and symbols while others feature a full-screen demonstration of how a game plays. These videos often include details about the game designer’s target payback percentage and can give players a good idea of how the bonus features work.

It is important to know how much you can afford to spend on each spin of a slot machine before playing for real money. Many people find it easy to get in over their heads when they play a new slot machine, and they can quickly go broke. Some casinos have a “max bet” option that helps limit losses by automatically reducing the amount of money you can wager per spin.
