I'm wondering if there is a bit of difference between Android and iPad. On my iPad game I'm falling behind with the purple drops from the mines which hardly ever seem to drop them and it seems harder to generate the beasts from the farms. Or maybe this is just part of the randomness that people are noticing. Not seeing differences between the two for gold coins or lucky dust.
I've not had the adventure drop purple or green on either the version. Has anyone else had these wisps from adventures? - don't want to use up too many precious nuggets if I can get the wisps in other ways.
