Sensei Sudoku app for iPhone and iPad

Modern day SUDOKU is a pure logic game, designed by Howard Garns in the US; although it true origins may go as far back as the end of the 19th century in France. It became popular across the world in the late 20th century/early 21st; with the Japanese becoming true SUDOKU SAMURAI. This app pays homage to their expertise using the Japanese word for teacher SENSEI in its name since its goal is to start you on your way to becoming a Sudoku Samurai. You can either put in your own “givens” in and ask it to help you solve a puzzle you have found elsewhere; it to give you a board for you to solve. Once entered, you can than use one of four additional buttons starting with the one marked NAKED to help you solve the SUDOKU puzzle entered. NAKED shows all the possible values for all the empty tiles. Try out the other buttons too to help you solve a given puzzle.
