Killer Samurai Sudoku X for New Year’s Day – this is the only place you can find these kind of Sudoku puzzles!
Warning: Today’s puzzle is very difficult!
Basically, not only do you have to fight against 5 interconnected Sudokus, but you also need to be carefull about the diagonals: ALL diagonals in the puzzle must contain one occurrence of each 1-9 digit. The diagonals are marked in the puzzle so you wouldn’t forget about them.
Fabulous work – yours is the best site that i’ve come across with the most challenging puzzles – my favorite are the butterfly killer samurai ones – but i’m afraid i go through them too quickly and lesser challenges have stopped being as satisfying. I appreciate it must take time to generate such puzzles, but more frequent ones like this would be great !
Thanks for your work so far!
Ciao!
