I’ve built a puzzle generator that creates logic grid puzzles using an algorithm designed to mimic how a human would actually solve them. It produces raw constraint statements like “Person:Carl, Age:30, Car:SUV, Hobby:TableTennis are all different people,” which are then passed through an LLM to turn them into clean, themed English clues. There are ~600 themes available, and difficulty levels range from very-easy to ultra-hard.

Today’s six puzzles are free to play; the full archives are behind a paywall.

Would love to hear your thoughts!
