Sudoku Portable

Sudoku Portable is a an addictive puzzle game originally created in France over 100 years ago. It features a 9x9 grid containing 9 3x3 grids. Within this you arrange the numbers 1 through 9. But, each number can only appear once in each of the 9 3x3 grids. And it can only appear once in each row and on each column. It's a simple concept, but it can get addictive quickly. This version features:

• Four difficulty levels
  • Easy: A great way to get your sudoku feet wet
  • Medium: More difficult sudokus
  • Hard: Harder sudokus, some of which will have more than one solution (according to many definitions, this is not a 'true' sudoku)
  • Impossible: Sudokus with so few numbers, you'll sometimes have to guess
• Entry of possible solutions for empty boxes (hold down shift and a number from the standard number row, not the numeric keypad)
• Automatic saving of your game on exit
• "Check Game" feature to check your current work
• "Solve Game" feature so you can see the solution to the current puzzle
• Resizable interface, so you can make the numbers as large as you'd like
