Sudoku's brother and sister

I love sudoku but kakuro is my new craze now. Click here----> kakuro.

Have you ever played hitori? hahaha...it's a not that new game but (kind of new to me) and it also uses logic. For me, Hitori is Sudoku's sister and kakuro is Sudoku's big brother. hahahahaha. Click here---->hitori .
