Hi MIF

I like those. The hermit puzzle is classical Fermi question.

Hi MIF;

Circling the square problem I believe is correct. Would you consider mentioning that geogebra can create these shapes and make this problem easier to solve than by cutting.

In the solution you might try putting a picture of the answer which makes a convincing display.

Oh, btw, if matchsticks are of the same length then the solution to that puzzle is incorrect!

Hi;

In the Path Plodding Puzzle another route is

start, finish, F, C, G, start, C, B, A, D,F,E,A, finish.

Wonderful. Included your circles diagram, bobby, and mentioned GeoGebra, thanks. And included your Path Plodding Puzzle solution.

Also mentioned matches don't have to be same length, thanks anonimnystefy.

Will post more puzzles when I can.

Hi MathsIsFun;

For the "Sticker-bility" puzzle your help solution is correct and there is only one solution to it.

But if you did not give any help then there are 74 solutions to the puzzle below. In case someone mentions that.

hi MathsIsFun,

Thanks for the puzzles. I'm still working through.

I've got to "It Must Be Matchic Puzzle"

Couldn't you have six equal matches in a tetrahedral format ?

"Hilda the Builder"

You could re-word this to ask for the least number of bricks. That way, just one answer.

Hi MIF

I like the second batch as well.

Hi Bob

Both solutions to the Matchic puzzle seem acceptable, but only with that wording and solution is it an original puzzle.
