Android Game: Trade Tycoon Billionaire

If you are looking for an android game that is more like on buy and sell trading stuff, this is worth checking out. It was made by Rhyzen Games and also has a part idle game where you make money on the side (not real money of course).  The only bummer here that I can see is that you have to wait for a time so the hearts bar would be filled. Maximum amount is 10. Hearts are needed here so you could fly to another country so that you could trade for a higher or lower price.

If you are looking about unlocking cities, you can see my post here.
