What are slots in online casinos?

The slot in the online casino is a display with 3 or 5 reels, which depict various symbols, and a spin button under the display. Sometimes in old-fashioned slots the back button is made in the style of lever, since initially in offline slot rooms such a lever served as a mechanism for starting reels rotation.
