Inspiration

We were inspired by how subs like r/ChangeMyView make people reflect on issues and topics. With misinformation and bad arguments spreading fast online, we wanted to create a social game that helps people spot faulty reasoning while having fun.

What it does

Find the Fallacy is a Reddit-based logic game where players identify logical fallacies in short statements. Players get fallacy cards, respond to claims, and earn points for spotting errors in reasoning. The community votes on answers, making it a collaborative and competitive learning experience.

How we built it

We built an automated game loop using Reddit’s API, Redis for state tracking, and a scheduler for rounds. Key features include:

• Extraction of discussion points from article
  
• Automatic generation of crosslink posts and comments per claim
  
• Card-based UI for selecting fallacies
  
• Peer review system for community validation
  
• Points, rewards, and leaderboard tracking

Challenges we ran into

• Creating meaningful, concise statements from articles
  
• Defining a manageable but rich fallacy set for gameplay
  
• Designing a fair and fun game mechanics
  
• Managing Reddit rate limits and asynchronous participation

Accomplishments that we're proud of

• Building a complete game loop with social moderation and evaluation
  
• Launching a real-time reasoning game in a subreddit environment
  
• Designing an educational tool that encourages better online dialogue
  
• Creating flexible post/comment flows tied to real content

What we learned

• How to convert complex discussions into structured microgames
  
• Designing for community consensus and subjective judgments
  
• Techniques for lightweight moderation automation on Reddit
  
• The value of combining gameplay with reasoning skills

What's next for Find the Fallacy

• Expanding the fallacy set with advanced logic patterns
  
• Adding streak bonuses, badges, and custom card decks
  
• Integrating AI assistance for fallacy feedback and learning
