I always have difficulty with logic puzzles. Usually, I miss making inferences that really make the puzzle's solution flow out. Are there any good books/resources that train people on logic puzzles? (I moved this from the brain teaser forum)

The kind of puzzle I'm talking about would go something like this:

Five bidders at an auction are hoping to secure a particularly nice piece of china. From the information given, can you work out where each is standing in the room, his or her bid, and the covert method of signaling each uses to indicate their bid to the auctioneer?

1. The initial bid of $200 was made by nodding, but not by the bidder in the middle of hte room.

2. Mr. Lott raised it to $225, but not by raising his finger; the bid made by that means was lower than Mr. Gowing's.

3. Mrs. Gavell didn't take the price to $250; the person standing on the right raised the bid to $275.

4. Mrs. Nock touched her ear to register her bid, but it was lower than that of the person sitting in the front row.

5. The bidder standing to the left signaled a bid by raising his or her programme slightly.

6. Mr. Sayle was standing in the back of the auction room.

Bidders: Mrs. Gavell, Mr. Gowing, Mr. Lott, Mrs. Nock, Mr. Sayle

Signal Method: Nodding, raising finger, raising programme, Touching ear, winking

Bid: 200, 225, 250, 275, 300

Position: Front row, middle, standing at back, standing left, standing right

All of the problems I'm referring to are of this format. I tried using the grid that they give in the book, but that doesn't help. Is there a systematic way to diagram and solve these without a grid? Thanks.

There are a few books that can help you improve your skills in solving logic puzzles. One of them is "Logic Puzzles For Dummies" by Denise Sutherland. This book features step-by-step instructions and exercises to help you understand the process of solving logic puzzles. It also provides tips on how to make logical deductions, how to create diagrams, and how to use grids to keep track of information. Another book is "Logic Puzzles 101: Mastering the Classic Puzzle Types" by Terry Stickels. This book covers a wide range of types of logic puzzles and provides detailed explanations of each. Finally, there is the online course "Logic Puzzles for Beginners" by Udemy. This course includes video lectures and interactive exercises to help you learn the fundamentals of logic puzzles.
 

1. How do I approach solving a logic puzzle without using a grid?

There are a few different strategies you can use when solving a logic puzzle without a grid. One approach is to start by identifying any definitive clues, such as statements that involve specific people or items. Then, you can use these clues to eliminate possibilities and make deductions. Another strategy is to group similar clues together and use process of elimination to determine the solution. Ultimately, the key is to carefully read and analyze each clue to make logical deductions.

2. What types of logic puzzles are best suited for solving without a grid?

Logic puzzles that involve a small number of variables and a limited number of possible combinations are ideal for solving without a grid. These can include puzzles involving a small number of people, items, or attributes that can be easily tracked and eliminated. More complex puzzles with a larger number of variables may be more difficult to solve without a grid.

3. Can I use any tools or aids to help solve logic puzzles without a grid?

While it is possible to solve logic puzzles without a grid using just pen and paper, there are some tools and aids that can be helpful. For example, you can use a whiteboard or a spreadsheet program to keep track of information and make deductions. Some people also find using colored pencils or markers to be helpful in visually organizing clues and potential solutions.

4. How can I check if my solution is correct without using a grid?

There are a few ways you can verify if your solution to a logic puzzle without a grid is correct. One way is to re-read the clues and your deductions to make sure they are all logically sound. You can also try solving the puzzle in a different way or using a different strategy to see if you arrive at the same solution. Some online puzzle forums or communities may also have resources or other solvers who can help verify your solution.

5. Are there any tips for improving my skills at solving logic puzzles without a grid?

Practice and patience are key to improving your skills at solving logic puzzles without a grid. It can also be helpful to start with simpler puzzles and gradually work your way up to more complex ones. Additionally, try to approach each puzzle with a clear and open mind, and don't be afraid to take breaks or come back to a puzzle later if you get stuck. With time and dedication, you can improve your skills and become more efficient at solving logic puzzles without a grid.
