This is the first sudoku puzzle I've made :) I hope you enjoy it!



Rules:
Normal sudoku rules apply: place the digits 1-9 once each in every row, column, and box

Each line must be either of the following:
1) Renban line - digits on the line form a set of consecutive digits in any order, without repeats
2) German whisper line - digits that are adjacent on the line have a difference of at least 5

There is a black dot between ALL pairs of adjacent cells with digits in a 1:2 ratio
