Great job on making a sudoku with a minimal possible number of clues! It was very interesting though I had to resort to a lot of guesswork. I think I was missing something because it felt significantly harder than the few 4/5 star sudoku puzzles I did earlier.
You don't need to guess for this puzzle. The trick with most minimal Jigsaw sudokus is that the shapes force squares to be the same number. Try working that in first and then focus on the numbers.
