If you want to improve your Sudoku skills, Sudoku 401 will help you learn and play. Sudoku 401 is a Sudoku game, a generator, a solver, and a teacher/tutor. First, it is a serious Sudoku game. - Puzzle generator for unlimited play. You will never see the same game twice. - Clean and simple game board, so you can focus on the playing instead of being distracted by colors and/or shapes. - Ability to enter the game manually, copy from newspaper, books, or other software. - Tap on a clue to highlight potential locations for the number. Tap again to go back to normal viewing. - Automatic or manual pencilmarks, which can be switched during the game play with one tap. - Automatically saves the game when you leave, ability to continue when you come back. - Option to use either symmetrically or non-symmetrical Sudoku boards. - Option to show error. Even more, it teaches you the logic and techniques of Sudoku, with its multi-step teaching system. All of the techniques are human logic, not computer brutal force. - Difficulty level is defined by the techniques used, not by number of clues. - Beginner: Full House, Hidden Single and Naked Single. - Moderate: Hidden and Naked Pair, Locked Candidates. - Challenging: Hidden and Naked Triple and Quad, X-Wing. - Difficult: Swordfish, Jellyfish, XY-Wing and Finned X-Wing. - Expert: Squirmbag, Finned Swordfish and Jellyfish (that also includes Fishy Cycle, Sashimi Fish and Turbot Fish), XYZ-Wing and WXYZ-Wing. - Extreme: ALS-XZ (Almost locked set) and Finned Squirmbag.
