The touch controls are awful. It’s hard to manipulate the camera. It’s hard to move the board/cube around. It’s hard to move the game pieces. Basically, whatever Unlock the King 3 wants you to do, it constantly gets in your way of doing it. And that, more than anything else, is why it’s impossible to recommend it. Even if Unlock the King 3 were the simplest, most straightforward game imaginable, it would still be a constant chore to play it. Couple lousy controls with gameplay that’s not all that interesting or intuitive, and you can see why — whatever the platform — it’s probably not worth playing.
