My favorite computer games these days are FreeCell and Sudoku. I have both on my iPhone and play them when I have a few minutes to kill.
Suzanne has been a regular crossword puzzle solver, and each day she tackles the puzzle in the newspaper. I was never interested until late last year I must have joined her in figuring out a few clues. I immediately saw the value in finding an iPhone app that would let you fill in the letters you knew and search for dictionary words. Upon installing it I began to supplement her efforts, referring to my iPhone as my "brain". I also use wikipedia on my iPhone to solve clues. Usually, I would tackle the puzzle after she filled out everything she could.
Here is a book we use, as well as the daily paper.
When Suzanne went out of town a few days last December I took a big step in trying to do the whole puzzle myself. Suzanne is such a wiz at it I didn't have much confidence. I would snap a picture of the puzzle and email it to her, and she would contribute answers via text or email back. We solved each day's puzzle and it was lots of fun and satisfying. When she went into the hospital for gall bladder surgery I bought her a book of puzzles to work on.
Now it is a regular activity for us, often solving a puzzle together. I still think she is so very good at it, and I tease her saying she is so smart. I still enjoy utilizing my "brain" to solve clues. Sometimes we'll polish off the newspaper puzzle before I head to work. Other times I'll help finish one after work where she got stuck. As often as not, though, she'll have filled it all in.
This is a fun little trifle we are able to work on together.
