Mystery Master

Welcome to the home of Mystery Master, the ultimate logic puzzle solver! Logic puzzles, also known as logic problems or logic grid puzzles, are found in magazines by Dell Magazines and Penny Press.

My logic puzzles range from easy to most difficult, and all (unless noted) have been solved by the Mystery Master application. The following is my mission statement.

My goal is to create a program that can solve any logic grid puzzle.

This is achievable. But the ultimate goal is to solve a logic puzzle without making assumptions (impossible?). Of course, you can still solve any logic puzzle on your own, or with a little help.

Here is my page of favorites. If you have any questions or comments, please email me at And if you appreciate my website, please consider making a donation. Thank you.

Because this site relies on donations and not ad revenue, your donation is important. Due to insufficient resources, I have put the puzzle solver on hold. The solutions are also on hold until the situation improves. Thank you for your understanding. But as a consolation, I now have 120 puzzles you can solve on your own.

Help on Logic Puzzles

The help page offers a series of YouTube videos and articles that explain various aspects of logic puzzles. And this button allows you to show/hide my images.

I have recently started a blog, where my first article "Model a Logic Puzzle in JavaScript" has been published by CodeProject. And if you're into hyper-rhetorical headlines, I have some fake news for you.
