This game should be named Cash Theivery instead of Cash Frenzy. Very few Cash Frezies, but alot of taking your cash. If you decide to pay for anything they will change the algorithm so you lose to keep you paying to continue to play. Also, the missions and challenges are made extra hard so you either lose your money or pay for emeralds to use to complete them. It's really a waste of time. Even worse is when you win free games the pay out is so bad, you can actually win better in regular game.
