Welcome to Mystery Master the ultimate logic puzzle solver! Many of my over 100 logic puzzles aka logic problems or logic grid puzzles were originally published by Dell Magazines or Penny Press and range from one star (easy) to five stars (genius).

This website can help you solve a logic puzzle if the puzzle has a corresponding JavaScript module (most of my puzzles have this). See help for more information. If you have any questions, concerns, or suggestions, please email me at mysterymaster@hotmail.com.

Here is my page of favorites. And finally, click on the Fun button to show/hide the fun image on a page.
