This is about half of my collection. At one time I considered taking a bunch to work and requiring anyone who had a question of me to solve a puzzle first because I am one of the "go to" people whenever someone has a question. I quickly realized that I would either scare people away or that people would end up wasting their time trying to solve these puzzles as opposed to doing what they are paid to do.

Aristotle's Number Puzzle
I found a solution to Aristotle's number puzzle:
Not exactly spoilerfree description here My solution came about by sheer dumb luck. I noticed there are 4 types of pieces: a central interior piece, 6 noncentral interior pieces, 6 exterior corners and 6 noncorner exterior pieces. While trying to place a bound on the possible values of one of the types, I tried an iteration that kept allowing me to place more pieces until the problem was solved! This puzzle is a real treat! Several times I was tempted to write a program to bruteforce (or maybe a little more elegantly) search for a solution, but I'm glad I persisted in solving it by hand.

I remember that was quite easy. Write in a table in Excel (by hand) all possibilities to make 38 with 3 numbers, like 1, 18, 19; 2, 17, 19; 3, 16, 19; 3, 17, 18; 4, 15, 19; 4, 16, 18; 5, 14, 19; 5, 15, 18; 5, 16, 17; etc, which is very easy, they are only 28, and there is obviously only one way to chain them to have the common corners around being part of two sums (they are 30, but you have to consider that 1 and 2 can't be part of any triple, because they appear only once, so they can't be corners, and in the same time then must appear on the sums of 5  why?  so this tells you that 1 and 2 are inside, 19 and 18 are outside, 19 can't be a corner, therefore 18 must be one). At the time I did that, I think it took me less than it took to some other guy to write a search program that would need few seconds or a minute to solve it. I remember also that my struggle was related to the fact that I (wrongly) reached the conclusion that 10 has to be in the middle, I don't know why, probably based on magic squares

Hi again all,
I am glad my wife bought me some fun metal hand puzzles. The solution to these two is just to twist the two pieces. Regards, Matt

Hi again,
Here is another of my fun puzzles. This one is only a little more difficult than the one with two nails. The solution involves a two step process. Enjoy the pictures. Matt

more puzzles
Hi everyone,
I got a new metal puzzle in the mail today. I solved it in less than 5 minutes. It was fun. Some of the puzzles that I buy are too difficult for me, so I just save them for later. This one is called Trapped Satellite. It was not too tough for me to figure out how to free it from its cage. But lots of fun. I bought the puzzle from BitsandPieces.com Also, I like to watch Mr. Puzzle, on YouTube and I get to see him solve puzzles. Good fun. Matt
