Yes, I have an addiction. It’s not so bad, though. I hope.
Sudoku. The puzzle game has its origins in France, and in Indiana. There is a grid, 9 squares by 9 squares with 9 3×3 squares inside. Here’s the idea:
- Each 3×3 square of 9 will have all numbers 1-9
- Each vertical row of 9 will have all numbers 1-9
- Each horizontal row of 9 will have all numbers 1-9
- There are no duplicates
I play the game on my iPhone. It’s cleaner than paper, and it’s like an endless supply of puzzles. And it keeps my brain occupied. I’ve included a couple of pictures – one of what the board looks like in ‘expert’ mode (obviously the hardest available), and one of what my best times are so far.
Try it out! If you don’t have an iPhone or iPod touch, you can find free Sudoku puzzles all over the internet.
