Sindoku 23 and 23 NC
Has anyone tried any of these puzzles? If so please let me know what you think of them.
David called it Isolated Sudoku; but if you abbreviate it to Isodoku, this has been used by Motris for Isometric Sudoku. Hence we can alternatively call it Singleton Sudoku and abbreviate it to Sindoku which is not used. If you google it you get tsundoku: buying books and letting them pile up without reading them. Note I have a bookcase full which is only there for when my Kindle dies and I do not have electricity (an everyday occurrence here in Nigeria).
Given that like most of you, I am locked in at home; I have decided to post regular Sindokus here and on the Player's Forum. So the rules again:
A singleton is a number with no adjacent numbers in the four cells.
Each square gives clues about the singletons in the four adjacent cells:
1. If there is no square then no clue is given.
2. A red square means there are four consecutive numbers.
3. A blue square contains four singletons.
4. A pink square contains two doublets e.g. XY and AB.
5. A square with a single number means the other three numbers are consecutive.
6. A square with two numbers means the other two numbers are consecutive.
I will give all the coloured squares. This means some may be redundant. I have not used this fact in my own solution for this puzzle; however, I have used this extensively in later puzzles.
In most cases I use some form of NC in creating the puzzle solution, as it makes for better patterns and it allows me to make two puzzles i.e. with and without NC.
If you want a third easier version you can of course use NC with all the plain clues - I do this for my bedtime puzzle
