I announced this one when I posted my first Outside Sudoku puzzle: it’s a non consecutive Outside Sudoku. Even though it looks like a regular Sudoku puzzle, you must follow one extra rule: two touching numbers must not be consecutive.
Outside Non/Consecutive Sudoku for Monday, January 18, 2010 – Difficulty: THINKER.
These Outside Sudokus are great. When will we get more?
DJ,
I love the Outside Sudoku variants.
I solve all the 3 of them in this site and it was very challengeable and enjoyable.
Each of them needs different technics to solve.
Donna, you’ll get some more TODAY (Jan 21)! 🙂
There is another non-cons outside on the Sudoku variants page.
nice one! Thank you 😉
