The first few minutes of this video covers news updates including what August may be like in our series A Story of Self-setting Sudoku.

The longer part includes discussion of, and a blind solve for, a Cryptic Sudoku by Palfly Kampling that is a variation on Renban lines requiring one gap in the middle. I have never solved a puzzle by Palfly, but having met at SudokuCon wanted to do a recommended puzzle which came from a recent SudokuCon stream.

Other Palfly puzzles are here including many puzzles he contributes to the “Sudoku Adventure” series with 6×6 variant grids.
