Sudoku Epic is a feature-rich Sudoku app for Android.

If you like the classic game of Sudoku, you'll love the Sudoku Epic app. It takes Sudoku gameplay to a level far beyond that offered by the traditional one-dimension version. It offers a "Killer Sudoku" mode for experts to put their skills to the test. There are also five different game modes, each of which offers a fun twist on the usual style of gameplay. One of the most novel features is the hidden word mode, which combines word search and Sudoku to create a letter-based version of a game usually played with numbers.
