Newspaper Puzzle Challenge - Sudoku Edition combines 8 puzzle games in 1 suite. The game has both original Sudoku game and adapted version of Sudoku that you've never seen before. I found that the twisted Sudoku is even more enjoyable than the original Sudoku.
The game has many cool features. You can use hint whenever you want. You can look at complete solution for each puzzle. You can print any puzzle board and solution.
