Place the digits 1 to 9 in every row, column and 3x3 standard block. Cells connected with a chess-knight move could not contain same digits. Besides grey painted cells form renban groups. These groups must hold consecutive numbers, in any order.
Solution code: First give the contents of Row 2 and Column 6, then give the digits which are included at least in 3 (out of 4) different renban groups ascending in order.
