Internet without online features

Actually a perfect game for waiting times, for example in subway, bus and train. Without Internet connection, the app crashes, however, with an error message and even tearing my entire tablet with - even though no online features are available (as far as I can see, because there's no duel mode, etc., but only any of these Facebook Gedöhns).

By implementing and game idea actually five stars for internet Forced I draw from two asterisks, and that the game with no Internet connection after an error message my Tablet wegschießt completely, another two. This is an absolute no-go!
