Here's a nice word challenge I found today. Go ahead and try it -- it'll keep you young.
By the way, the answer to #1 is here, which you can peek at if you highlight the box just below. I'll leave the other 6 to you to solve.
A R I A
R I N G
I N T O
A G O G
Also, on puzzle #7, consider what might be even more cool about this answer, if the first word started with a different letter.
