KenKen!

It's been a rainy couple of days in Rome, so walking around and touring hasn't been my first choice on the potential activity list. I've been doing a lot of reading - Giovanni Boccacio's The Decameron to be exact - for my final project, but during one of my breaks, I discovered something wonderful! And so I'll share it with all of you... KenKen! It's the newest puzzle game, invented by a Japanese math teacher. If you're a fan of Sudoku, I promise you'll be addicted by the third game. Play with caution...
