I have a board game idea. Now what?

Every published board game started exactly where you are right now, as an idea in someone's head. The distance between an idea and a finished game can feel enormous, but the first steps are simple and cheap. You do not need art, a publisher, or money. You need to get the idea out of your head and onto the table as fast as possible.

Start by writing the idea down in plain language. What do players do on their turn? How does someone win? What is the moment of the game you are most excited about? A single page is enough. This document will change constantly, and that is the point. Writing forces you to answer questions you did not know you had.

Next, build the roughest possible version you can play. Index cards, scrap paper, and borrowed pieces from other games are the standard tools of the trade. Your goal is not to impress anyone. Your goal is to find out whether the core of the game is fun, and you can only learn that by playing it.

From there the path is a loop: play, notice what is broken, change it, play again. Most designers go through dozens of these cycles before a game is ready for strangers. The sooner you start the loop, the sooner your game gets good.
