Show HN: Trading cards for learning – 16 albums, 2.7k cards, learn by collecting

https://tradingpicturecards.com/
1•Manuel_TPC•1h ago
Hey HN! Solo dev here.

I spent a year building this because I learn best when knowledge stacks visually. Traditional trivia is forgettable—this uses collecting psychology to make it stick.

How it works: - Answer questions correctly → unlock illustrated cards - Use cards you've collected as hints for harder questions - Knowledge builds on itself, like learning should

Right now: 2 fully playable demos (AI History, Streaming Wars) + 14 more albums in progress.

Background: I'm a robotics engineer turned neuropsychologist. This merges what I know about learning retention with gamification mechanics.

16 albums planned: AI • Streaming Wars • NFL • K-Pop • Marvel vs DC • U.S. Presidents • National Parks • eSports • Fast Food History • Blockbuster Cinema • Revolutionary Inventions • Books That Changed the World • Urban Mysteries • Women in Sports • American Painting • Music Journey

2,733 cards total. Building 5-8 cards/day.

Try the AI demo: https://tradingpicturecards.com/aia/

Feedback very welcome. What would make you actually use this?
