Bonus puzzle! SudokuBank is brand-new, just two days old, and has a lot of appeal for both puzzle setters and puzzle solvers. I was invited to set a puzzle for the launch, and this is the result.
As a setter, SudokuBank includes many constraints for which I normally would use custom code, like “Ambiguous Kropki Dots,” which are new to the blog. Each dot is either a white or black Kropki dot, but which? That’s up to you to determine!
Next week, we’ll go back to SudokuPad, but today, enjoy the alternative solving experience. Feel free to create an account on the site, or not!
Rules:
Normal Sudoku rules apply.
Cells along a Renban Line form a set of consecutive digits in any order, without repeats.
Ambiguous Kropki: Cells separated by a gray dot either differ by 1 (like a difference kropki dot) or have a ratio of 1 to 2 (like a ratio kropki dot).
Estimated difficulty: 2 out of 5
