A slot is a narrow opening, especially in a wall or door, into which something can fit. It can also refer to a position or time period, as in “I have an 11:00 to 12:00 slot.” The term is a variation of the word schedule, from the notion that one’s work is planned at specific times throughout the day. In the context of airports, a slot is a time at which an airline can operate on a congested runway or in restricted airspace. Airlines typically compete for slots at airports, and the International Air Transport Association holds two annual slots conferences that allow them to secure the rights to operate there.
A slots RTP is an average figure that tells you what percentage of your total wager a particular slot machine is expected to return. It is a good thing to look for when choosing which machine to play as it gives you a good ballpark figure of how much you can expect to win over the long term.
Some slots allow you to choose which paylines you wish to run with during a game, while others are fixed and require you to wager on all lines. This difference can make a significant impact on your winning potential, so be sure to research the options available before playing. The number of paylines you choose to play with can also affect what types of bonuses and features get triggered during a spin, such as jackpots, free spins or mini games.
