The Hardest Sudoku(圖1)-速報App

17 is the minimum number of clues in any proper sudoku (i. e. sudoku with a unique solution).

The app contains a database of 50 000 sudokus with only 17 numbers initially. Thus this database includes some of the hardest grids ever, although a lot of grids presented are not that difficult as one may expect. Future selection of the super-hard puzzles is intented (with contribution of solvers using the app).

The app offers:
