How to get to the snowcraft minigame?
Solution 1:
From the Final Fantasy Wikia
In the Dawn of Souls version, the player must hold down A and keep pressing the B button. Similarly, in the 20th Anniversary release, the player must hold down X-button and keep pressing Circle-button 22 times. In the iOS version, players have to shake the device to activate the minigame.
I'd guess that the Android activation is the same as iOS.
