HQ Trivia Solution Bot

A HQ Trivia (💀) solution bot mostly built over the course of 3 days in 2018. Old, rough code.

Techniques inspired by "I Also Wrote a Bot for HQ Trivia" by Benjamin Schwartz.

Process

• Watches a folder for phone screenshots of the current question in the game (for example taken by screenshotting a connected iPhone via QuickTime Player's Movie Recording feature)
• When a new screenshot is added:
  • Crop to core text
  • Convert to greyscale
  • Increase contrast
  • Use Tesseract OCR to find the question & 3 answer choices, using the game's Circular font to improve the chances of matches
  • Find key phrases from the question (proper nouns, filtering punctuation)
  • For each answer choice:
    • Count the number of occurrences of key question phrases in that answer's Wikipedia page
    • Count the number of ocurrences of key question phrases in that answer's Google search results page
  • Suggest the answer with the most matches, or the least if the question contains 'not'
