Randoku is a brand new concept of Sudoku, which gives you unlimited challenges that need to be solved, each challenge having a unique solution.
It is based on levels, each of them being more difficult than the previous one so we make sure you won't get bored.
Need a little help? Use features as Hints and Drafts if you feel you need a bit of inspiration.
And don't worry if you need to use your phone for something else in the middle of the game, we will save the progress for you. More Info »
