Normal sudoku rules apply.

Draw lines from the vase in R9C7 to every flower. Lines can only go up, left or right, never down. Lines stop when they reach a flower, and every line must ultimately end with a flower. Lines cannot share cells with one another or go back on themselves.

If a line visits a cell, the digit in the cell determines which direction the line moves in next.

On an even number, lines go north.

On a 1 or a 3, lines go west.

On a 7 or a 9, lines go east.

On a 5, lines branch and split into two lines travelling perpendicular to the direction the single line was going in. Each individual branch obeys the above rules.

The digit on the vase is even.

Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Lines cannot pass directly through these dots. Not all dots are necessarily given.

Along every line, adjacent digits must have a difference of 2 or more.
