Re: New Puzzles 6

Hi MIF

I found these slightly harder than the ones before, but still very nice.

For the "What is the pattern" puzzle it couldn't actually be stated that Stephen is the author. It is a well and long known one. Look-and-say Sequence

Re: New Puzzles 6

Hi MathsIsFun;

Very nice puzzles. My favorite is "broken stick."

"Cards in a square," is a mutually orthogonal Latin square. These are pretty widely known with many open questions.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Good point. I have just put him as Author for all these new puzzles, there may be others that are mis-cited.

Most of the others look original.
