Samurai SuDoku, Killer Sudoku and more

According to the comments, a lot of people enjoyed the IQ Killer posted on Friday. It’s time to cool your brains off a little, with the today’s “COOL” puzzle. For those who haven’t had enough, I posted a really tough Diagonal classic Sudoku.

We’re doing quite well on the top 50 Sudoku sites list. A few days ago we finished 4th! We’re normally in the top 10.

Have fun and send more feedback!
