I miss my college logic class. Without a doubt, logic was my favorite class in college. I scored so well in the class that the teacher told me that I didn’t even have to take the final. If I made a zero on the final I would still have an A in the class. Today, logic is my favorite past time. Whether I am trying to solve a Sudoku puzzle, bending my mind around a “false” logic puzzle, solving cryptograms or working on any other kind of puzzle, I love solving logic puzzles!

I like logic puzzles much better than riddles. Riddles try to fool you through having so many possible answers that you cannot find the right one. An example of this problem is a riddle such as “Too much for one, enough for two, not at all for three. What am I?” The challenge of a riddle lies in the fact that there is no starting point and an endless array of possible answers to sort through. A person practically goes through every word or object that they can think of in order to solve the puzzle. There is no way to solve the puzzle through simple deduction. Instead, the person solving the puzzle must just guess a lot of different things until they find something that matches the needed criteria. (BTW, the answer to the riddle is “A Secret”. )

Logic puzzles are more structured. They have a clearly defined premise upon which to start solving the puzzle and a clearly defined objective. For example, there is an old “false” logic puzzle which goes as follows: A traveler comes to a point where the road splits. On both paths there is a sign. The traveler knows that at least one of the signs is false. The signs say: (A) This is the road to take unless it is B. (B) A Dragon Awaits along road A. Which road should he take?

This puzzle has a clear starting point “At least one of the signs is false”. This means one or both of the signs are false. And, the puzzle has a limited number of possible answers: Either road A or road B. Because there is a clearly defined starting point and a clearly defined objective, the puzzle can be solved through simple deduction, without any guesswork. (The answer is that the traveler should take road A.)

Of course, there are many types of logic puzzles and logic puzzle books. I have been working my way through one book called “Lateral Puzzles [1]”. The book has some really unique problems involving having to look at the questions in a different manner in order to find the solution. For example: Apart for being 15 letters long, both of these words have something in common and they are the longest two words that have this property. What property am I talking about? The Words are Parasitological and Overimaginative. The answer is that they both alternate consonant-vowel.

As I love logic puzzles, I am likely to put more posts up about different kinds of logic puzzles. I am happy to give hints or give advice on any logic puzzle that someone else might be trying to solve. If you have any puzzles that you want help solving or if you want to learn some of the tricks and tactics of solving logic puzzles, comment and tell me! I will see what I can do to help!
