Mystery Master


Michael Benson


Welcome to the home of Mystery Master, the ultimate logic puzzle solver! My Logic puzzles, also known as logic problems or logic grid puzzles, are found in magazines by Dell Magazines and Penny Press. I currently have over 100 logic puzzles which range from one star (easy) to five stars (genius). You can solve any logic puzzle on your own, or with a little help.

Most of these logic puzzles were created by others. I am not a brilliant constructor of logic puzzles, I am a software engineer with the goal to create a program that can solve any logic grid puzzle.

After many years with Yahoo!, I moved my website to GoDaddy. I am also using a different email address. So if you have any questions or comments, please email me at

The HQ page offers a series of YouTube videos and articles that explain various aspects of logic puzzles. My first article "Model a Logic Puzzle in JavaScript" has been published by CodeProject.

Here is my page of favorites. My button allows you to show/hide the main image(s) on a page. If you want to show your appreciation, please consider making a donation. Thank you.

There is a version of the Mystery Master application for newer Android devices! You can find my app in the Google Play store. Around 60 of my puzzles are solvable in my app.
