Place the digits 1 to 9 in every row, column and 3x3 standard block. Two same numbers can not touch each other diagonally. Additionally two main diagonals and the four shorter diagonals can't contain any repeated digits. Besides grey painted cells form renban groups. These groups must hold consecutive numbers, in any order.
Lösungscode: Both diagonals, first the one from top left to the bottom right, then the one from top right to the bottom left.
