I always loved Sudoku. It is super fun. When i was in my 11th standard, i discovered sudoku. It is still interesting, but I was constantly looking for something else to replace sudoku and i found one. It is called KenKen.
New York Times crossword puzzle editor, Will shortz, introduced this puzzle in New York Times last month. He is the same guy who introduced sudoku to the world. I recently read an article in Time, titled, "Is KenKen the next Sudoku?" Then tried one 4x4 puzzle and really loved it.
Actually 4x4 is really really easy. 5x5 is also pretty easy. 6x6 can be quite tedious. Initially it took a bit longer to solve the 6x6 puzzle. But after a while, it is also manageable. I want to try the 9x9 puzzle. It is called the "Einstein puzzle". But before that, i gotta get used to other easy ones.
It adds a bit of maths to the traditional sudoku. So people who love puzzles, try this one. Warning - It is really addictive.
