Today, Sudoku Uno is available for iPhone, iPad and Mac. The dual player Sudoku Duo is available only for iPad.</p><p> All products are based upon the same powerful Sudoku engine. This allows Sudoku Uno &amp; Duo to provide an almost infinite number of Sudoku games categorized in 3 levels of difficulty. </p><p> This Sudoku engine uses human logic to solve Sudoku puzzles. It can thus precisely evaluate how difficult to solve a board is going to be. The levels of difficulty are mapped to the techniques needed to solve the puzzle. Not the number of empty cells. </p><p> The same engine can also help you with smart hints. Not only will it help you solve the puzzle, it can explain the reasoning behind the hint. </p> <a name="Features"></a><br/> <h2>Shared Features</h2> <ul> <li>Three levels of difficulty: easy, medium, hard</li> <li>Difficulty levels are determined by techniques to master, not by number of givens</li> <li>Unlimited number of Sudoku games</li> <li>Green & red pencil notes</li> <li>Optional automatic pencil notes</li> <li>Intelligent hints with explanations</li> <li>High scores</li> </ul> <a name="SudokuDuo-iPad"></a><br/> <div class="image-left" style="padding-right:2em;"><img class="imageStyle" alt="Sudoku Duo" src="../images/SudokuDuo.png" width="213" height="213"/></div> <h2>Sudoku Duo for iPad</h2> <p> Dual player Sudoku.
