Traditional Pen and Paper Logic Problems
The rest of the logic puzzles listed here are all traditional logic problems, which will need to be printed before solving. Most do include a puzzle grid.
Occasionally, my readers have asked me for blank grids, for doing other logic puzzles. So I decided to post some blank grids for your use. These grids are available in Microsoft Excel and PDF file formats. To download, right click on the link, select "Save Target As", and select the location on your hard drive that you'd like the files.
