Hello -

I'm a big fan of Logic puzzles (LOVE Logic Art, Picross), but I have problems solving the logic puzzles that have tables. I've read the little tutorial on this site, and it hasn't helped me much. The only one I've ever solved is in the Original Logic Problems April 2008 issue - #16 Snow Motion. I also almost succeeded on #17, Camel Lot, but had mixed up a couple of people. When I do these I always get frustrated, and I want a cross-grid, and I have a zillion notes everywhere. I don't like bringing in outside paper and I usually don't have much space in the puzzles books to write. Any help? I tried puzzle #21 Say It with Gumby, and abandoned it mid-way through.

I used to have the hardest time with the table puzzles too. I always avoided them. Now....I LOVE them and I usually do those first!

I found it helped to start by practicing on the puzzles that only had a few short clues and not very many items involved in the "discussion". That way I didn't have to worry as much about so many things going on at once.

Some things that help me:

* Unless the puzzle is VERY short, I do all my work on a separate paper. I always keep my "puzzle notebook" with my puzzle books.
* I always make a table at the top of my page just listing all the items involved---All first names, all last names, all colors, all cities, etc.
* As I solve the puzzle and enter items into the puzzle grid, I cross them off of the table I have made---helps me with elimination
* I have developed my own shorthand specifically for solving logic puzzles to save on extra marks and keep things more clear for me
----some of the shorthand is basic "=", "+2", ">" etc.

A shorthand I use very often is for the common occurance of things such as "Jack and Jane wore the red shirt and the blue trousers in some order" I will write:

Jack | red shirt
Jane | blue trousers

That always means that each item on the left side of my line matches up with exactly one item on the right side of the line. It also means that every item on the left side of the line is on a separate line of the grid in the puzzle book and every item on the right side of the line is on a separate line of the grid in the puzzle book.

If another statement in the puzzle said: "The doctor and the dentist were Jack and the one who wore blue trousers in some order" I would write:

doctor | Jack
dentist | blue trousers

Then, I can immediately see that in the first statement Jack could not have been wearing the blue trousers because the second little diagram I wrote clearly shows me that they are two separate people.


I don't know if that will help you at all (I hope it WILL), but I do know that when I always wrote out all possibilities and used shorthand that it really helped ME with the table puzzles.

I think it will help, I'll give it a shot. I've always disliked using excess paper to solve the puzzles, because it just feels ... I don't know, like I shouldn't be using it. But I'll obviously have to start working with it! Thank you!

I do prefer table over grid since many times it easily get marked in wrong grid. whenever this happens, you would have to erase and start all over again. I also use Excel to make a table so this way I can do assumptions just by copying the tables and do all the assumptions on each table. You can eliminate them this way till you get to one table. Doing assumptions on grid is really disaster if you took a wrong assumption.

You could take a look at my program at www.logicpuzzlesolver.com, which helps in solving logic problems. The program draws a the grid for you, and then you can input the clues. The program will make as many deductions as it can from the clues. It's easy to make assumptions as well, as you can undo your assumptions back to where you made the assumption.

The program is quite free, so please do take a look and tell me what you think.
