Hey Kana,
yes it was available on iOS, until Apple removed it from the AppStore. According to Apple it simulates gambling and was therefore removed.
Currently I'm rewriting the game in libgdx (Java) and try to add multiplayer support. Technically there seems to be an option to cross compile libgdx to iOS, but since Apple has removed the game anyway it's not on top of my list. Which sucks, as I have an iPhone myself.
