Gamifying a niche hobby can be a great way to get attention and start conversations in passionate communities. Here’s how one creator did it with LEGO fans.

Algorithm:

1. The creator built a simple, fun website where users could choose their favorite LEGO minifigure from two random options.
2. The site uses an ELO rating system - when you pick a figure, its score goes up and the other’s score goes down, creating a dynamic leaderboard of the most popular minifigures.
3. They posted the site in the r/lego community, which has almost 2.6m fans who love interacting with anything LEGO-related.
4. The post quickly gained traction - members enjoyed the interactive format and started playing with it, sharing their results, and comparing favorites.
5. Along with positive engagement, the creator received valuable feedback from users suggesting new features, such as:
   • Adding missing details to certain minifigures
   • Creating a leaderboard view from most to least liked

Why This Works:

• It’s interactive - people can participate, not just look at something.
• It’s tailored to a specific niche community that’s already passionate about the subject.
• It’s simple and quick to use, which encourages sharing.
• It naturally sparks discussion and friendly debate in the comments.

How to Scale This:

• Create interactive tools or games for other fandoms or collector communities.
• Use comments: besides posting updates for their game, the author answered users' questions in comments when they asked something about the LEGO figures

Related Ideas:

• Poll-based games for movie characters in film fan subreddits.
• Rank-your-favorite style games for sports teams, music albums, or video game characters.
• Interactive “battle” tools for product preferences in hobbyist communities.

This Is How It Looks Like

What users say

By posting a fun and relevant minigame to a highly engaged community, the creator drove traffic to their site, gathered useful feedback, and gave fans something worth sharing.

Final Notes

• Engage niche communities with something interactive and relevant to their passion.
• Keep the barrier to entry low so anyone can participate instantly.
• Use the comments to gather ideas and build trust with the audience.
