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!

    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…
