(Non-consecutive) Consecutive Sudoku 12×12
Consecutive 12×12 Sudoku puzzle
After a bit of a break to meet a major book deadline – the non-consecutive part of the title of this posting – I’m back with what seems to be one of the most popular types of puzzle, a Consecutive Sudoku. I wanted something a little bit different, though, so this is a Consecutive Sudoku 12×12. I personally always find Sudoku 12×12 pretty similar to regular 9×9 Sudoku to solve, unlike something like 16×16 which personally I’d never really bother with (apologies to anyone who loves them!).
In order to make the consecutive nature of the 12 possible values obvious, I’ve used one- and two-digit numbers rather than digits and letters. So the rules are simple: place 1 to 12 into each row, column and 4×3 box whilst obeying the white consecutive markers. Wherever there is a white consecutive marker between two squares then the difference of value in those two squares is 1; and conversely whereever there is no marker the difference is always greater than 1.
So sorry for the break – hopefully ‘normal’ service will now be resumed! 
And good luck with the puzzle!

Wow. Put a puzzle such as this one up FIRST before you step away from your blog for a while.
That one was difficult for me. The consecutive chains did not follow the usual patterns, and the pairing up of candidate numbers was interesting.
One thing I did was change 10,11,12 to A,B,C in order to help with candidate write-ins and started thinking in hexadecimal.
I admit that I have been distracted lately by playing boardgames like Dominion Intrigue and Wasabi! all weekend, but I eventually got there.
I do like the consecutive and skyscraper puzzles.
