Explain the Rules of a Game to Someone Who Has Never Played

You want to play something and someone at the table has never heard of it. This produces a clear explanation in three parts: what you are trying to do, what you actually do on your turn, and how it ends. No wall of rules. Just enough to start.

Explain the rules of {GAME_NAME} to someone who has never played it.

Keep the explanation to three parts:
1. The goal: what you are trying to do or achieve
2. The core mechanics: the two or three things a player does on each turn or move
3. How it ends: what triggers the end and how you know who has won

Use plain English. No jargon unless you immediately define it. Assume they are an adult who is not familiar with this type of game.
