Has anyone heard of the game 'Sudoku Quest'?
You can download it from here. It claims that it contains an endless amount of 'boards', and is free to download.
However, there is one drawback I can see without trying it out; it rates a 34-clue puzzle as 'hard'. I'd like to see the 'easy'.
If anyone knows of it or is going to be downloading it, let me know what you think of it.
