This method will get you a lot of coins. The glitch will multiply your coins, so the more coins you have, the better.
Step1. I am going to put a card up for 100 coins and you buy it.
Step2. You then sell it back to me for 100
Step3. I am going to sell it for the amount of coins you have and you buy it.
Step4. You then want to dashboard and restart the game up and you will have double the coins you had before!!
