Good morning to all! Hi Mark and Deb! Nice to see your picture!
Brunette - and overnight!! Congrats Deb and Mark- Enjoy grand-parenting.
Sometimes I wonder why I even attempt the tough ones and certainly why I bother this late at night
Good night all nearly midnight definetly bedtime
Good morning, Mark and Deb!
Hi, Grandma and Grandpa!!
What an appropiate picture! (Hope Speller isn't around). Best wishes to you all.
4:38, one tricky bit, there it was as fast as i could fill it in.
1) Start with 22, the given puzzle, Unique Possibilities (UP) to 25
2) c5=8==c8=8--b9=8==b9=2--h9=2==i8=2--i8=7==c8=7, forbids c8=8 UP 27
3)i8=8==b8=8--b9=8==b9=2--h9=2==i8=2, forbids i8=37, UP 81
They do not look old enough to be grand parents!
Mark and Deb - You are a very happy looking couple. I agree, you do not look old enough to be grandeparents. By the way, how is that baby? Any pictures?
22:51 I did some stupid mistakes... but in the end I solved it.
Happy couple! Best wishes to grandparents!!!
Great feeling to be a grandmother - I know, I have 4 years old grand daughter. She is wonderful...
Looking good as a set of new grandparents should! Welcome to the best club in the world...being a grandparent.
Hey Nick,
I always check your time as a guide. I'm way slower than you, so if your time is much over 30min I don't even attempt the tough one that day. So thanks, keep posting times.
Nice picture Deb and Mark. Congratulations!
Oh look, it's Mark and me!!! This pic taken on 21st October this year.
Were you two twelve when you had Nicole????? Have a wonderful time of grandparenting. I won't be there any time soon; the kids just got married in July, and Cathy wants to finish school first and work awhile, so it looks like 3-4 yrs or so. It's great that you are young enough to enjoy and play with them. Best wishes to you all.
Hello Deb and Mark. Lovely photo of you both.
Dave from Minnesota,
Do you use any program to solve the Sudokos?
Hi Gaby!

I use Simple Sudoku, written by Angus Johnson and free to the public, available at www.angusj.com/sudoku. It will display the possible values, provide color filtering and is a real time saver for set-up. It can provide hints, but does not necessarily find the chains needed to unravel more complex puzzles.
Good, but easy.
