SudokuMaster

SudokuMaster is a small app for creating, solving and playing Sudokus.
You can choose between 5 different levels (easy, simple, normal, difficult, hard).
You can request for a hint for a selected field.
A field can be marked by a long touch.
Sudokus can be saved and loaded and exported in a PNG file.
Every created Sudoku is solvable but there might be more than one possible solution.
