The solution you have listed for this puzzle is incorrect, as far as I can tell. It states that E=8, F=9, G=5 and H=3.

The correct solution should be E=9, F=8, G=3 and H=5.

I don't have that magazine, but does it look like this?

It's very similar, Frances!

I don't have a Flickr account, but here is a link to mine and my husband's Twitter page and I've "tweeted" a photo of the puzzle. The answers are shown on it, the numbers in parentheses are PennyDell's (incorrect) ones for four of the triangles.

This was a puzzle I made last year, and depite the editing, the correct values of the triangles remained the same. Oops for the editor, as there was no reason to change the answer (except for the switching of H and I)! smile

Frances, let me switch gears for a minute! LOL

How about Triangle Sums? This little puzzle is driving me crazy. I know there should be a logical way to approach it rather than just by trial and error but I can't see it. Do you ever solve these, or even make them, perhaps?

Thanks for any help! smile

Hi Bernadette,

Yes, I have made and solved Triangle Sums. Test-solving is required before submitting a puzzle, and say I have a dozen of these to check. I also have to ensure each has only one solution. With about a hundred possible arrangements for each one, I've got me a shortcut. It uses both logic and trial & error. I'm not going to detail why this works, but trust me, it makes short work of things! smile

There are only 4 possible ways to put in the 4 corners, so that's what we'll check. Here is an example of a Triangle Sums where I have entered the middle square, and arbitrarily set in one of the arrangements for the corners.

https://www.flickr.com/photos/149284839@N08/35860243495

Find the sums of the 3 numbers in each big triangle.

7 + 7 + 1 = 15
5 + 2 + 9 = 16
9 + 6 + 4 = 19
6 + 9 + 6 = 21

Then add the 4 single numbers (1, 3, 5, 8) to each sum this way: the largest single to the smallest total; second largest single to the next smaller total, etc.

15 + 8 = 23
16 + 5 = 21
19 + 3 = 22
21 + 1 = 22

Do all 4 final sums match? No. Switch corners 1/5 and 6/9 and try again. No. Then 6\7 and 4\9 are placed incorrectly. Switch them and they're in the right places now. Two tries left, with 1/5 and 6/9. One will work. Ta da!

Frances.

Thank you so much for sharing your shortcut, Frances! I knew there had to be a better way than spending hours plugging in numbers! LOL

I certainly do appreciate your help!!! smile

Your method worked like a charm, Frances! I was able to correctly solve the Triangle Sums problem I'd been working on in about ten minutes! smile

Thanks again!

Yay! I'm so glad it helped you solve it.

So am I! Thank you again for all of your time in writing the explanation out for me!

You may have to start your own "Dear Frances" help column! smile smile

Oooh, that sounds scary! I only have a knack for some puzzle types, and would soon be "found out". LOL

Now, could someone please explain to me how to solve Letter Logic?

Okay, so maybe the column isn't a good idea! LOL

Frances, I wish I could return the favor and explain Letter Logic to you, but I've never tried solving that puzzle before and just reading the directions a few minutes ago has made my head hurt. Good luck! smile

Frances,

I posted a message last night about Letter Logic but I came back and deleted it as I just wasn't happy with the explanation I wrote.

I've solved about four of these now. In the three "below" words, I've been eliminating the two-letter combinations for the answer word that won't work because those two letters are both in the same "above" word, and according to the directions that's not allowed. Then I've just been trying out different four-letter combinations, remembering that the word can't start with any of the letters in the far left column, per the instructions.

Every correct answer word I've found so far has ALL of its four letters contained within the three "below" words. The instructions don't specifically say that all of the letters of the answer word can be found in these three words, just that each of the three contains two letters of the word. I'm wondering if we're supposed to assume this anyway?

Just some thoughts....I still think I'm using more guesswork than logic. :/

Thanks, Bernadette, for the suggestions! You've got me having another go at Letter Logic. After fiddling around for longer than I'll admit, I found two more things that can help.

1. When a "below" word has 2 letters that can't be in the correct positions for the answer, then one of the remaining ones has to be. So if AXLE and WORM and "above", and MARE is "below", then the answer is either M _ _ _ or _ A _ _.

2. If the 2 letters taken from each of the 3 "below" words were all different, we'd have a 6-letter word. If 4 were different and 2 the same, we'd have a 5-letter word. So, at least 2 letters of the answer will be repeated in the 3 "below" words.

ETA: You could also have one letter of the answer repeated 3 times in the "below" words.

And I solved some! I had to use a separate piece of paper, though, for all my figuring. As for all the answer word's letters in the "below" words, while all the examples of the puzzle I checked had that, I'm not sure if it's a rule. Would be another thing to help, though.

Thanks again for helping me try to solve these tough puzzles again!

Frances.

You're welcome, Frances, and thank you for your additional input!

Funny how some of these "little" puzzles can produce the biggest headaches! LOL wink

They sure can! For others who may want to see an example of Letter Logic, here is a link:
