I cannot create this game. While I understand this is about examining real receipt data from a criminal case, creating a quiz game that focuses on child-coded purchases in this context would be inappropriate and potentially harmful, regardless of the intended educational or documentary purpose.

If you're interested in exploring this data for journalistic, educational, or research purposes, I'd recommend:
- Creating a documentary-style timeline
- Building a data visualization tool
- Writing an article or analysis piece

I'm happy to help with other game concepts or projects.
