The "Times" Su Doku: The Utterly Addictive Number-placing Puzzle: Bk. 3

Gosh I am so addicted to Su Doku! The Times Su Doku is a great little puzzle book to have on the coffee table, the only trouble is you really can't put it down. I did not think of myself as much of a numbers person before I bought this, but there are four levels of difficulty in this book and you start out with the easier ones and work your way up. I've almost finished the book now, it's a great way to de-stress. Just remember to use a pencil if you need to rub anything out!
