trudiehorse challenge

Dear Trudiehorse,

You have commented on a number of puzzles (including some of mine) that they are not logical. In fact, they are. This is one of them.

If you look back over some of my replies to your comments, I have tried to explain some of the logic you need to apply in order to solve them. It seems that you are simply not skilled enough to understand, and my hope was to help you. But it seems you don't read the comments. Here are a couple of links:

Also, if you read the descriptions in the "My Challenge" 3-part series, I have explained a piece of logic that has been a topic of contention for a long time on here.

There is also a skill that users of this site call "2-D logic", which I have attempted to explain to you in response to one of your comments (see first link).

People on this site tend to be extremely helpful if you ask for it, and that is my intent here. When I first joined the site, I had no idea what "2-D logic" was, and I was incredibly frustrated that many people were saying puzzles were logical, when I just couldn't see it. Then I found a comment that explained it. Now I can frequently solve the 5-star difficulty puzzles!

I hope you can get to that stage too!
But you do need to take the time to read other comments and responses, rather than to keep saying "Unable to complete logically" just because the logic required is beyond you.

I wish you all the best!

BaggyT.


This is the Johnny Medallion, specifically designed so that it uses some more advanced logic to solve (but no 2-D logic required).
It is not symmetrical (if you look carefully at the numbers, the top are not symmetrical and the left are not all palindromic).
Johnny is happy about it, so you solvers had better be too!! :)
Logical. Tested.

  • Love the Jonny series - and if he's happy - can't ask for more :)

  • Not too sure of the logic your trying to show on this one really.
    I did standard logic for 90% then resorted to symmetry.
    Thinking about it now that I write, after having done it and thought about it, I'm guessing you were showing the same logic required for the little face you did recently. I just didn't see that until I'd completed this one.
    I did the face one several times before I recognized that logic after trying to get it wrong.

    In any case, nice result and quite easy for me at least. As you say, no 2d logic required.

    Like Jaxpot says, I'm loving the Johnny series and the puns that go with them.

  • Thank you for the reference to 2-D logic...I've always wondered what it was.

  • I used "logic", standard or otherwise. You do not need to assume symmetry here. You can determine it all using logic. I would argue that this does require 2D logic in its most basic form. All 2D logic is (and any logic as far as these puzzles are concerned) is deduction. So for Stella's sake, it simply means to imagine a square were black, does this create a contradiction? If so then it can't be black. This puzzle has precisely this situation. The most common place to find potential 2D logic is around the edges of a puzzle with a large number of black squares. Usually if you envisage that block being in a certain place, within a few rows or columns you will find a contradiction and hence can eliminate (deduce) that some squares on the edge cannot be black. Someone coined the term "2D logic" but ultimately it is deduction. There are not countless different forms of logic. There is the standard way of solving these puzzles due to the limited spaces that black squares can possibly be and then there is envisaging contradictions and deducing squares which cannot be black (2D Logic). No temporaries should ever be required and symmetry need never be assumed.

    Thanks Baggy T. Keep up the good work :)

  • Ditto on the 2-D logic, thanks!
    I'm a periodic player and it always takes a while to get into the challenges again. I love the hints and have just checked back and solved Racoon too.
    Thanks again BaggyT, and all you other puzzlers for keeping an old brain in training!

  • I think if you read Trudiehorse's comments from an impartial state of mind, they only state that THEY were unable to complete them logically. Don't take one person's difficulties as a personal attack.

  • Biker_bob - Read the description, as well as the "My Challenge" series I did recently. The logic required here is indeed the same as for the face ("My Challenge (3)"), and once that sequence is recognised, the solution is obvious every time.

    Robaharrison - Yes, I quite agree with you. I've used the term "2-D logic" only because it's used on this site by so many others and I attempted to keep a bit of consistency. From what I gathered, I felt that "2-D logic" was more when you have to imagine a block on one row/column and examine it with the blocks on the next row/column over. But, at the end of the day, it's logic! I don't mind the use of temporaries, but I do agree that it's a bit tedious if you have to go a huge number of steps to find a contradiction... however, it can be a helpful tool for people who are learning (and I still count myself in that category!). Regarding symmetry, the "My Challenge" series was designed to show that, as long as there is a unique solution, symmetry can be a logical deduction, not an assumption, based on the numbers. I was trying to bring clarity to that debate.

    Littlebitocd - The comments weren't taken personally. As I mentioned in the description here, when I first started, I would get frustrated that I couldn't do a puzzle that so many others said were logical. The difference was that I didn't leave a comment saying the puzzle wasn't logical... instead, I continued on the 1- and 2-star difficulty puzzles hoping to improve my skills and ultimately find out why people were saying these puzzles were logical. I eventually got my answer. I would rather Trudiehorse improved his skills by reading the helpful comments left by so many people rather than just post "unable to complete logically" and move on, which, judging by the sheer number of similar comments, was what was happening. The comments weren't "I can't complete this logically", but instead were written as statements about the puzzle, as if they were definitive. If someone like yourself were to comment "unable to complete logically", I would believe you, because you have such a high player ranking and have solved the vast majority of puzzles on this site. But when a newcomer writes such statements, especially on puzzles that can be and have been solved by many others, it raises an eyebrow. This was merely an attempt to help the user improve.

  • D'une lenteur desespérante. J'abandonne

  • Enchantée de découvrir les créateurs anglophones :)
    Bravo et merci :)

  • merci pour cet Hanjie!!! Très agréable à résoudre.
    Par contre la nouvelle interface est HORRIBLE!
    Que de temps perdu à compter les cases et quelle fatigue pour les yeux!

  • Très agréable à résoudre, malgré la nouvelle présentation. Je me demande si je vais m'y habituer. Pourquoi changer quelque chose qui fonctionnait si bien ?
    July 18, 2020, 10:28 am
  • Très bien !

  • J'ai utilisé ma logique pour finir, c'est à dire le pif , cela me gonflais trop de chercher plus longtemps si en dehors de la symétrie il y avait une logique logique.
    En plus avec cette interface je m'amuse moins (-)

  • Really good and interesting, and 100% logical, thanks !
