Diculty Levels
All Sudoku puzzles have one solution that can be obtained by logic, without guessing. But they
dier in diculty based on the number of givens and the diculty of the logic required to solve the
puzzles.
When you start a game, you choose a diculty level: Easy, Medium, Hard, or Extreme.
Starting and Resuming Games
If no game is in progress when you start Sudoku, you start a new game. Tap the diculty level
(Easy, Medium, Hard, or Extreme) to begin the game.
If a game is in progress when you exit Sudoku by tapping the Back button or Home button, the in-
progress game is saved. When you play Sudoku again, the saved game resumes.
To abandon a game and start a new one, tap the Back button and then choose a diculty level for
the new game.
What You Can Enter in a Square
You can enter these numbers in each square:
Values: Values are what you want to enter to solve the puzzle. If you have a 3x3 square
that already contains the numbers 1-9, except for 7, you would enter the value 7. Values are
indicated in a font that looks like it was written by hand.
Notes: Notes are your notes about possible values. They appear as smaller, hand-written
numbers.
