DONT TRUST OFFER WALL AND IRONSOURCE. This game was fun for awhile, but does start to run it's course after a few months. However, do not fall prey to the offer wall trap. While some of the smaller offers may work fine, any larger offers, and especially if you spend money in another app to complete, will NOT process and you have little-to-no recourse as IronSource support does not help you and refers to undocumented device conditions you must meet (example: advertiser tracking on).
