Now that I’ve posted my 500th puzzle, I am sharing the Sudoku I contributed to the Daily League last Saturday, along with the Sudoku I’m contributing for it today. I didn’t post the Killer last week on my blog because I wanted the space saved for the special puzzle.
Remember that you can solve the puzzles from the League online on the Sudokucup Guest League page with a 24h delay.
Common Rules – Follow regular Sudoku rules.
For Killer – The number in the top-left corner of a dotted cage is equal to the sum of this cage’s digits. No digit can repeat within a cage.
For Extra Regions – Each group of nine grey cells must also contain the digits 1 to 9.
