Erica 12 (Fog Edition)

Just one, easy, very approachable fog Erika! :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Normal sudoku rules apply.

Fog: The grid is partially covered in fog. Entering correct digit will clear fog from its cell and diagonally adjacent cells. No guessing is required.

German whisper: Neighbouring/adjacent digits along a green line have a difference of at least 5. Line is thick so that it can be visible on corners of the visible cells.

V: Digits in cells joined by a V sum to 5. Not all Vs are given.

I really enjoyed this, as with all of your puzzles, thank you so much!

For some reason SudokuPad was flagging things as if the chess king move rule was in place, which made it slightly harder to work through...!

SK: Thank you for a kind comment! SudokuPad has some issues lately, this is a SudokuPad error, not related to the puzzle itself.

Thank you for your puzzles. The Erica Series is being very helpful in helping me improve my skills. The fog was very useful in helping me to better focus on the current openings and not get lost in the larger picture. Thank you.

I so love an almost pure GW puzzle!

This wasn't too hard, but definitely a verry enjoyable sudoku. I guess I'm so familiar with gw rules that they just make me feel very comfortable solving the puzzle and I can just have fun.

I mean i suppose it was easy but it took me 35 minutes to find that last breakthrough. I guess i just don't know what to look for. ;)

Definitely a very approachable puzzle, I only got a little stuck once and just about smacked my forehead when I realized I'd missed some very obvious logic
