Mastersoft sudoku

Update 4 July 16: just changed iPhones and downloaded app on it. It didnt load my statistics, tried Game Center and Facebook, oh well, still a great sudoku...
Had mastersoft sudoku on my windows based phone and loved it, rated a sudoku master. Choosing different colors of numbers when going down a path of uncertainty is a big plus. This is the sudoku to get!
