A slit or narrow opening, especially one for receiving something such as a coin or a letter. Also: a place or position; an assignment or job slot. (Dictionary of the English Language, American Heritage)

The term slot refers to a specific period of time in which an activity or event can take place. For example, if you plan on attending an important meeting at your workplace or a public event, it is recommended to arrive early so that you are able to secure a seat in the room. Getting in at the last minute will likely lead to an uncomfortable experience and may compromise your ability to participate fully. In the same way, it is recommended that you book a slot for your holiday trip in advance so that you do not run into any unforeseen circumstances that may compromise your plans. Health care providers often rely on the use of time slots for booking appointments with patients. The slots help them to schedule urgent visits, routine check-ups and consultations with new clients more effectively. Similarly, many online casinos utilize the slot to organize their games and make it easier for players to find their preferred titles. Some slot machines have multiple pay lines and include a number of bonus features, such as free spins, re-spins, wild multipliers and jackpot rounds. These extras can increase the value of a player’s bet without any additional expenditure. The payouts for these games are calculated according to the pay table that is shown on the machine or, in the case of video slots, displayed within a help menu.
