The slot is an area in hockey where the puck is passed between the face-off circles and the goal. There are two types of slots: low and high. The low slot is the area in front of the goaltender, and the high slot is in the middle of the ice, above the face-off circles.

A narrow trench is dug in a slotted area. The slot is usually wide enough to pass a cable, but it can be narrower. Slot trenching may be done with conventional excavation techniques, but typically, minimal impact techniques are preferred. Hydro excavation is a preferred method because it is non-destructive and is often more efficient.

In addition to pay tables, slot machines also have other indicators, including a candle that flashes when a pay-out has been made. The player can also press a service or help button on the machine to contact the operator. Some slots also feature a carousel, which is a series of machines. A carousel of slot machines is similar to a casino floor and is grouped by the theme of the machines.

Slots are often computer-programmed, which makes them much more flexible than their mechanical predecessors. Moreover, they are not limited by the size of their reels, as was the case in the past. A vintage mechanical slot machine could only hold so many symbols on a single reel, while a computer-powered slot can hold up to twenty symbols per reel.
