A slot is a position in the roster. This position can be the TE, WR or SB and is often used by quick guys that like to run routes in the slot. This is because they can get open a little more easily than the X receiver and have a couple of steps before contact with the CB.
A slots pay table is the information that explains how a particular slot game works. This can include a description of the different reels, paylines and bonus features that the game offers. It also shows how much the regular symbols pay out and the rules for any bonus features. Normally, the information is shown as small tables that are displayed on the screen. These are normally coloured to make them easier to read.
In modern electronic slot machines, a taste is a very small amount that is paid out over time to keep the player seated and betting. This is contrasted with the very large amounts paid out by some machines as a jackpot. These are not always given to the player, but can be won by a machine with a very high hit frequency or in some cases if there is a technical fault. For example, electromechanical slot machines had tilt switches that would break a circuit if the machine was tilted. This was a common cause for mechanical failures that required a restart. Such technical problems are not usually present in newer slot games.
