Many, if not all mobile card games require players to play on only one device. I guess they want to avoid schemes where multiple players play on the same account (or one player opens the game in multiple devices at the same time) ^^;
In these games if you want to switch between iPhone and iPad (in case you own both), you need to transfer authorization from one device to another. Basically you can’t no longer play on previous device (unless you switch back).
iPad has a nice big screen, while iPhone has wireless data network so I can play outside (my iPad is not LTE version since I don’t think I’ll use it much outside ^^;)
Apparently for this game, switching between iPhone and iPad is relatively convenient. It’s still annoying, but not as troublesome as the other games I know. I think for Love Live School Idol Festival, you would need to enter long passcode.
Go to メニュ -> データ引き続き. You would need to connect to either Mixi, Twitter, Google or Facebook account. In Twitter case, you would also need to confirm by e-mail (not sure about others).
The scenario is typically like this.
Let’s say I’m currently playing on iPad and I want to switch to iPhone.
– Open app on iPhone
– On start screen, it will detect you’ve been playing on other device (iPad).
– The game will restart, now with データ引き続き option on start screen. Connect to either your Mixi, Twitter, Google or Facebook account (will switch to Safari to press some confirmation).
– The game will restart again. This time you can start playing.
So yeah, need to see the start screen three times. But since you just need to press buttons instead of typing stuffs as long as you’re already logged in to those services (in my case, Twitter) it’s still not too bad.
You can reach situation when the game is open in both devices (for example, if I didn’t close the game on my iPad). The previous device doesn’t seem to catch up with the action you took in current device. I’m too scared to take any action in previous device (iPad in my example) since I might be considered ‘cheating’ and get banned etc.
In a situation where you don’t remember which is the current device, you can just exit the game and restart to make sure. If you can play immediately after the start screen, that’s the current device. If not, just do データ引き続き and it’ll become the current device.
Playing iPhone on outside while iPad at home kinda feels like those Vita/PS3 games where you play on Vita outside, play on PS3 at home (except that there is no additional cost in this case) ^^
