In Final Fantasy 2, there is a hidden memory minigame that you can access once you get the snowcraft. The original version of FF2 didn't have the minigame, but other versions do.
However, I haven't been able to find any instructions on how to access the minigame on the Android version of FF2. It doesn't make sense that it wouldn't be there when it is present in both the PSP version on which the Android version is based and in the iOS version (why have it on one mobile platform but not another?).
How can I get to the snowcraft minigame?

I'd guess that the Android activation is the same as iOS.
