Continuing with Two-away puzzles, I thought today I’d post a somewhat smaller challenge – an 8×8 Jigsaw Sudoku version.
The rules are pretty much what you’d imagine: place 1 to 8 into each row, column and bold-lined jigsaw piece. Numbers with a grey bar between them must have a difference of 2 (e.g. 1&3) and numbers without a grey bar between must have a difference that’s not 2. (This is important to ensure a unique solution!)
Good luck!

This one was fun.
Very easy compared to the samurai star earlier. I think I may be getting the hang of seeing the chains and looking for the odd/even crossover.
You know that when you shift back to 1-away consecutive sudoku it is going to mess us all up again.
Now to get some work done before I start on that jigsaw samurai…

After the previous two puzzles I found this one much easier. I am getting a bit more used to spotting the chains now.
