Sometimes you just can't see the woods for the trees. I do a Sudoku from our local paper every day. Yesterday I got completely stuck. I hate it when that happens!
I use one on an app on my iPad. Helpfully it wobbles and glows red if I pick the wrong place! I love doing it but oh some days, I just can't get the logic! Nice picture
Haha- I am in the minority- I hate these things!! But that is because I am terrible at anything beyond basic math. Give me a word search, crossword puzzle or jig saw puzzle instead! Good for you- I am impressed with anyone who can do these.
