Sameera Reddy doesn't rest until she achieves what she wants. Her latest craze is Sudoku. "I find Sudoku very tricky and challenging. So much so, that it's difficult for me to put down the paper until I've solved a game. I was getting worried about my obsession but I've realized that I am not alone in the madness; the whole country is in its grip. The Sudoku fever has caught on in the country!" she says.
