Drive Members to New Subreddit

I'm launching a brand-new subreddit to promote a new game i am building - https://footballcoachgame.com/ it's a High school football game where you manage your team and try to win a national title. This is a brand new project and I want to use Reddit first to build a community for this app. My single objective is to turn that empty space into a lively community by bringing in real Redditors who already share an interest in the topic. I am looking to attract people interested in High School Football and football games in general.

I need a promotion strategy that fits naturally within Reddit’s culture—no spam, fake accounts, or paid-upvote schemes. Think smart cross-posting in relevant subreddits, engaging comments that point users our way, creative content seeding, and any other white-hat tactics you know will motivate hobby enthusiasts to press Join and stick around. 20 karma accounts are a must !

Deliverables
• A concise promotion plan detailing tactics, subreddits targeted, and expected timeline
• Implementation of that plan until we reach an agreed subscriber milestone
• A brief wrap-up report summarizing actions taken and measurable results

If you have previous successes growing fresh communities on Reddit (or similar platforms), share a quick example and the time frame it took. I’m ready to start as soon as you are—let’s spark life into this new subreddit together.
