Consecutive Sudoku

Green dots mark where adjacent cells contain consecutive numbers (like 3 and 4). No dot means NOT consecutive!

Rules:

Example: A dot between two cells means one could be 2 and the other 3, or one could be 5 and the other 6. No dot means they differ by 2 or more!

Green dots show consecutive pairs. No dot = NOT consecutive!
