puzzle 23: here is my version of the rules:
numbers in the circle give the number of neighbouring cells (horizontal, vertical and diagonally) that are also odd/even, that means: if there is a 4 in the circle, there must be four EVEN numbers arround, if there is a 1 in the circle, there is only one ODD number arround.
All numbers that fulfill this rule are signed with the circle.
