Bogo deal on puzzles (Differences Count part 1&2)

Hi,
I have a great interest in alternative sudoku variations, especially killer sudoku. I saw this puzzle with a ruleset I have not seen before so I wanted to make a video on exploring this logic. I have a part 2 coming for this puzzle series since I wanted to do the 9x9 in a seperate video. Thank you for watching the video and reading this, you are awesome!
The puzzle is made and released by Marty Sears and Sujoyku. (Differences count series)
