Explanation
Indoors means inside a building, not outside. It is most commonly used as an adverb to show where an action happens; for example, the kids are playing indoors because it is raining. You can also use it as an adjective to describe something happening inside, but this use is rare; in that case, the word “indoor” is usually used to describe activities or places inside a building, like an indoor game or an indoor meeting. People use indoors to show the location of activities or to compare with outdoor activities.
