Rules:
1. Normal sudoku rules apply.
2. Digits separated by a white dot must be consecutive, digits separated by a black dot must have a 1:2 ratio.
3. Bridges: In the grid, there are three rivers that have to be crossed. This only can be done by building some 'bridges'. A bridge is a vertical line of length 3 which completely passes through a river, and on which adjacent digits differ by a multiple of 3. In building the bridges, one must ensure that each column and each 3x3 box contain exactly one bridge.
Puzzle:
Solution code: Columns 3 and 4, starting with column 3. Write down as an 18-digit number.
