I hit no when it asked me to rate on my iPad so I didn't get it even though I tried rating manually later. I ended up downloading it on my iPhone and playing and this time when it asked to rate I tapped rate. I then when back into the game and had to open the WBID menu twice before it showed up on both my iPhone and iPad.
If you only have one device and tapped no, the only way to get the rate box again is to install again. You can either wait for an update or remove the app and reinstall it. The help section claims the game backs up your progress, cards and coins to iCloud and will restore it if you uninstall and reinstall, but if it does, it appears to do so on per device because my progress made on the iPad wasn't restored on my iPhone. The WBID rewards are shared between devices since they are tied to your WBID account.
repeat the first bonus battle over and over. when all of your energy is depleted on all characters, go into your phone/ipad/ipod settings and set the date forward 1 day. go into the app and all your energy should be refilled. exit the app then reset the date to normal. you can do that everytime your energy is gone. the bonus battle nets you like 4k credits and if your characters are leveled enough shouldnt take you more then a few minutes. --- "My judo throws are the best, the best throws in the world.
