Logic solvable
Product Killer
Inspiration for this type comes from Qodec.
Solve online in Penpa+ or in Sudokupad.
Like all of my sudoku variants, this puzzle can be solved by logic alone. Guessing is not required and also no sophisticated solving techniques are necessary; just plain and easy sudoku steps and of course the intrinsic logic this specific variant has to offer. In case you don't find that logic or get stuck, feel free to ask for a hint in the comments below this puzzle and I'll be happy to help you.
Apply classic sudoku rules.
The small numbers in the upper left corner of each cage (dotted outlined region) indicate the product of the digits in that cage.
Solution code: Row 9

Just two stars? It must be an April 1st joke... :-P

Wonderful puzzle! I found the mid-solve quite subtle (3 stars for me), but enjoyed all of it from start to finish. Thank you, Richard!

With more puzzles and constraints to choose from on this website than we deserve, sometimes it is easy to get caught up and neglect the more simple but beautiful puzzle that first got us into sudokus. This was a fantastic puzzle that made me think and appreciate everything sudoku has to offer. Thank you for setting!
