Swordigo does, but I've had problems with it. I got stuck playing on my iPhone because it refused for several days to go to the cloud at all and so my save on the iPad stayed way behind. Finally one day it decided to work and I switched back to the iPad. I'm not planning on playing on the iPhone anymore. In fact I deleted it from the iPhone so I wouldn't be tempted and then get caught again. LOL.
The game itself is really good, but my experience with iCloud save syncing, at least with this game, was not a good one, unfortunately.
