The word Slot comes from the late 14c. meaning “hollow at the base of the throat, above the breastbone.” Its origin is uncertain. Other possible sources include Old Norse slod, which is also a synonym for slot. Its use in the sense of a slot is recorded from the 1520s, while its use in the context of a slot machine dates back to 1888. A slot is a hollow, narrow opening.

In the early days of gaming, slot machines were installed as a distraction for casual gamers.

You can also delete a synonym by hovering over it and clicking on the X. A slot may have more than one value, so it is important to map all slots to their appropriate values.
