# Simple Logic Puzzle Generator

### You are given a collection of clues - can you determine who is guilty and who is innocent?

By

A terrible crime has been committed; the police have rounded up their suspects, and collected clues as to their innocence or guilt. The puzzle is: can you discover who should go free, and who will be detained?

Raymond Smullyan was an amazing inventor of logic puzzles, who filled dozens of books with them in his lifetime. In one book, called What is the name of this book?, he gives a puzzle where there are three suspects to a crime, and a small number of clues. The clues are of the form "if A is guilty, B is innocent", and so on, and it's possible to deduce everyone's innocence or guilty solely from the clues, using logic alone.

I like this kind of puzzle. If you do too, you'll keep coming back to this page and its "logic puzzle generator". Below, is a randomly generated puzzle like the one in Smullyan's book. Can you solve it?

If you think you know if someone is guilty or innocent, you can click on their name in the line-up below the clues. Keep clicking (or tapping) to toggle between "guilty", "innocent" and "unknown". When you've decided everyone's innocence or guilt, another button will appear allowing you to check your answers. There's also a link to generate a new puzzle, and change the number of suspects.

By the way, feel free to use the puzzles generated here any way you like. I only ask that, if at all practical, you give a link back to this page.
