Welcome to our sweet and wonderful community @Oakley_Arney! This is a very interesting question! It is probably due to the fact that different games have different features and fun, so I guess it is only natural that there are separate amounts of gold bars in the piggy bank in different games. For example, in Candy Crush Jelly Saga, the max is at 50. In Soda, it is at 100. It could also be that this might be in a testing phase, to see if this new adjustment gains enough popularity. I hope this helps!
