Help your brain stay healthy with Sudoku! Improve your Sudoku skills with the beloved Sudoku Classic, the most popular number puzzle game for players who want to challenge their brains from time to time! The rules are simple and easy to learn, but like most puzzle games, you really need some time to understand and master. The object of the game is to fill the 9x9 grid with numbers. Each column, row, and 3x3 block can contain numbers 1 through 9 only once. And that's all you need to know, really. But the challenge is to find out which numbers in which and which column misses which numbers. It sounds complicated, but it's all based on logic and a little brain teasing.
