When I started the Expert Sudoku Solver site, I promised that I would try to get round to reviewing as many sudoku packages as I could. I confess to being a bit slow on this.
However, it has been pointed out to me that I forgot to put the price on each of the reviews I have done so far. This has now been corrected and you can find the updated reviews in the reviews category on the right.

I hope you are starting to feel more like an accomplished sudoku solver if you have been following along with this series on how to solve an easy sudoku puzzle. We are close to the end of this puzzle now, so this post will the be the end of this mini-series. I hope to bring you something related but a little bit different in the next post. If you missed the start of this mini-series, you can find it here.
I left you with the challenge of working on row 5 of our puzzle. If you don’t remember that, hop back to the last post and refresh your memory and we will pick up from there.

Welcome back to this short series showing how to solve sudoku puzzles from beginning to end.
At this point in the puzzle, we are starting to see several nearly complete houses and so we can either complete them or use them to “lock down” candidates that we can then eliminate from other boxes.
In the grid following on from the last post, you can see this at work in cells 8,8 and 9,8. There are only two values that are still left in that box and so they can not exist in the rest of the whole of column 8.

Hopefully you found a series of fairly easy 2’s and 4’s from the puzzle as we left it in the previous post. You should have been able to complete them like this. Again I have tried to use darker colors to show later entries.
Series of 4s and 2s filled in.
If you start with box 7 and see how the 2’s in the boxes above affect it, you will see where I have started.Then move to box 8 and box 2. After all that, there is only one unconstrained place in box 2 for the value 4. This gives us the 3 in that box as a freebie (not a sudoku term!) and the 4 in box 8.
Once we have these values in place, the next group of values to go in are the 5’s. See if you can do these before taking the jump.
