Mean ORC 24
A couple with diagonal clues:
Meandoku (strictly extra) The following colour clues apply:
Green: the sum of the two adjacent cells is 8 or 9 only
Blue: the sum of the two adjacent cells is ten
Red: the sum of the two adjacent cells is 11 or 12 only
Yellow: the sum of the two cells is below eight
Black: the sum of the two cells is above twelve
Odd Row and Column - ORC - so it is:
ORC: odd rows and columns are 1-9 no repeat; even ones are not (i.e. they can repeat).
NN: no nonets
For all cells:
AK: Anti-King - diagonally adjacent are not equal
FNC: Ferz Non-concecutive - diagonally adjacent are not consecutive
NC: adjacent cells are not consecutive
Note where there is a block on the corner it means that both the crossing diagonals apply.
I solve these in JSudoku control-right click allows you to remove the row and column constraints. Note recursively solve works but deduce a move is flawed.
I would be grateful for your views on difficulty.
