This was a puzzle created as part of my "Contemplating Constraints" series. Designed to be a puzzle to introduce someone familiar with sudoku to some of the basic logic for constraints they may not have encountered before.
This was the hardest puzzle in the series; designed to introduce someone to Between Lines and Lockout Lines.
Rules:
- Normal sudoku rules apply.
- Grey lines are between lines. Digits on the lines must lie between the digits in the circles at the ends of the line.
- Blue lines are lockout lines. Digits placed in diamonds must differ by 4 or more and the digits along the attached lines must be higher or lower than the digits in the diamonds.

While this is not a hard puzzle I have done a video of the entire "Contemplating Constraints" series that includes this puzzle.
The link is the video that contains the puzzle, starting at the 1:12:00 point (for some reason links with timestamps on LMD have the timestamp trimmed).
Solve video on YouTube - jump to 1 hour 12 min
Note: the video is in English.
People who do not want any help should just ignore the video.
