How do you submit a board game idea?

To submit a board game idea, first research the publisher you want to approach and review their submission guidelines, as they often have specific requirements. Prepare a clear and concise game proposal that includes a description of the game, rules, target audience, and any unique features. Some publishers may also require a prototype, so be ready to create a playable version of your game. Finally, send your submission via their preferred method, whether it be email or an online form, and be patient while waiting for a response.
