You have a naked quad in row 3.

(And if that didn't make sense, feel free to ask for clarification.):)

hi there skibum,

First, How many 4s do you need in column 7 ?!

Second, Look for a hidden double in row 3 (or as vidarino said, a naked quad which is in the same row that would achieve the same result)

Third, look for an interaction between row 3 & box 3

Ahhhh, I guess one 4 per row is enough!!!! I completed the puzzle with your suggestions. I've had lots on my mind lately and think it's adversely affecting my sudoku solving!! So I thank you very much for your help. I feel very honored to have friends from around the world to help me with fresh sets of eyes to solve my puzzling puzzles. May you both have a wonderful day!

Windbell,

I agree with Cathy W's comment in another thread that giving the final solution is not the same as giving the next logical step. I am sure that you mean well but I think that in general, people prefer the latter.

The contraint of the game is already the solution of the puzzle~
The player was only overlook the number on the puzzle, so I post the solution as no tricky thing was there for this one~
:D

People don't want the solution. People want to solve it. There's a difference.

Uh, that's both ridiculous and disingenuous. You've made 5 posts since joining recently -- all of the contain the bare solution and nothing else. If a friend asked you for help with a puzzle, woud you just snatch it away and fill it in for her? Or just tell her to look in the back of the book for the answer? If your child or student asked for help with homework, do you just give the answer and gloat how much smarter you are?

Here's an idea -- READ the forum for a day or two *before* posting.

Again, do not post a bare solution unless it is specifically asked for. It is *very* rare that anyone is looking for the bare solution.
