Solve sudoku puzzles in News on iPhone
In sudoku puzzles, you place the numbers 1 to 9 into squares in a grid consisting of nine blocks with nine squares each, so that every number appears exactly once in each block, row, and column. Each sudoku grid comes with a few givens—squares already filled in.
Apple News+ offers subscribers new sudoku puzzles every day in three difficulties: easy, moderate, and challenging. Easy puzzles include more givens, while challenging puzzles require more complex strategies to narrow down options for each empty square.
Note: Sudoku is available on devices with iOS 18.2, iPadOS 18.2, macOS 15.2, or later. Apple News, Apple News+, and puzzles aren’t available in all countries or regions. See the iOS and iPadOS Feature Availability website.
