Official Description

Whether you're a Sudoku expert or beginner you'll treasure the experience of Sudoku Masters by PuzzleBoss. 40 beautiful photos provide an elegant backdrop against which you can play three difficulties - Regular, Hard and Masters. A gentle difficulty curve makes the Sudoku puzzles gradually harder the more you beat. Guided mode helps by eliminating all the rows, columns and groups that already have a number.

If you're unfamiliar with Sudoku it's a Japanese puzzle game that requires putting the numbers 1 - 9 in each row, column and 3x3 group without repeating any number in any row, column or group. Tough stuff!
