Following are some different sized grids to use in solving logic problems. I provide a table or illustration on the page with the puzzle, but several of my visitors have asked why I don't provide grids.

The answer to that is space. A table is simply a series of html commands and takes up less room than a grid, which has to be constructed in a paint program and saved as a graphic. Therefore, I decided to make several different sizes of grids, doing one each, and then placing them here.

Printing

With Internet Explorer, a person should be able to highlight the grid they wish to use and print it out by using the File, Print option at the top of your browser. With some printers, when your print options box appears, you may also have be able to chose an option such as "selection" or something similar. I'm not sure how it will work with users of Netscape or other browsers.

One friend who uses Netscape said he was unable to using highlighting to select the particular grid he wanted. Therefore, I've put only two grids per page so that if one has problems printing out just one, they don't need to print out all ten to get the one size they need - the can simply print out the one page that the grid is on. I hope this will solve any problems with printing. :-)

Entering Information

When using the grid for a logic problem, it is important that you enter the categories in proper order. In the example in the logo above, you can see that on the grid shown, there is an A, B, C, D, and E, in that order, across the top of the grid, but with the categoris going down, you have A, E, D, and C. By entering your information into the grid in this manner, B intersects with C, D, and E also, and looking at the E going across, it intersects with B, C, and D, but not E. In other words, by using the layout this way, then no letter, which represents a category, intersects with itself.

Also remember to enter your variables under each category in alphabetical order, and with numbers, either descending or accending, in order. With days of the week or months of they year, they should be entered in descending order, as they appear on a calender, and not alphabetically.

Grid Sizes

There are ten grids here in different sizes. The 3x4 grid is a grid of three variables under four categories, the 3x5 grid is a grid of three variables under five categories, and so on. I have put two grids on each page and the links are below. Simply click on the link to the page that has the grid you may want. This should make printing them out easier, especially if you use a browser that makes it impossible for you to select just one grid to print off.

Also, be prepared for a few pages of just black and white. After all the colorful pages you've viewed throughout the site, it may come as a bit of a shock! LOL
