I've been after the next great leap in puzzles and perhaps I've found it, although it looks very similar to a leap we made a few years ago. No, there's no denying that the puzzle is still Sudoku.
But this is next generation Sudoku. Sudoku in the extreme.
Then there's the opportunity to change grid size. And you thought Sudoku always came in 3x3s. Oh no, you can shrink to 2x2 or expand to 4x4. However, I found the largest grid size very confusing with so many options displayed in each little square.
It was difficult to know whether I was still playing Sudoku or a completely different game. There are various levels of difficulty but most interesting of all is that this Sudoku watches you play.
