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.

While most of these logic puzzles were created by others, my goal is to create a program that can solve any logic grid puzzle. To help achieve this goal, I am asking people to become a member. Membership is free, but I'm hoping it will lead to more involvement by others.

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. Click on the Fun button to show/hide the main image(s) on a page. 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.

If you have any questions or comments, please email me at And if you want to show your appreciation, please consider making a donation. Thank you.
