Ovi Gaming Review:
"Rotoku is definitely for the hardcore (Sudoku) fans, but it does provide a challenge that can be tailored from “difficult” to “mind blowingly impossible” and that's something I'm more than happy with. It's value for money, it can be played over and over again, and the satisfaction from solving a puzzle is a wonderful reward for the player who puts time into mastering the mechanics of the game."
