Place the digits 1 to 9 in every row, column and 9 irregular areas painted with different colours. Different from a standard chaos sudoku 3x3 blocks also must have digits 1 to 9. Besides shaded cells form renban groups (there exist 6 renban groups). These groups must hold consecutive numbers, in any order.
Solution code: Row 4, followed by column 4
