Butterfly Killer Samurai Sudoku

Weekend Special: Butterfly Samurai Killer Sudoku with diagonally adjacent cells!

This puzzle consists of 20 (twenty) 9×9 Sudoku sub-puzzles. There are 5 groups of 4 puzzles. Each group of 4 is arranged Butterfly-style, and those 5 groups are arranged Samurai-style.

Please make sure you understand how the puzzles are arranged before attempting to solve the puzzle.

Also, be careful when solving this one – with diagonally adjacent cells it’s sometimes easy to miscount the number of cells in a cage and if you do that, you get the cage-sum combinations completely wrong!

Enjoy!

  1. Huzzah… these are my favorite as well. I’d like to make one minor request, though: How about some identifying information (number, date posted) in the image? I print these out to work when I have time, but then when I mess up my last copy of one, I have a heck of a time figuring out which one to pull up to print more copies of. Maybe it’s just me…

  2. Thanks for your kind comments. 🙂

    Jeremy, it’s a good idea and I will make sure to put some info on these puzzles when I post them next time.
