Party game classic
Spin the Bottle is probably the simplest party game in the world: an empty bottle is spun in the middle, and whoever it points to goes next.

Rules
It needs zero preparation and fits any group. If you don't fancy endlessly inventing tasks, let Luminary serve up ready-made questions and dares instead.
Everyone sits in a circle around an open space, with the empty bottle in the middle.
Whoever's turn it is spins the bottle firmly and waits for it to come to a stop.
Whoever the neck of the bottle points to answers a question or takes on a small task, for example truth or dare.
Then the next person spins. As many times as you like, with no fixed end.
