Arena Mode
The first way to get easy Coin is to go to Arena mode, then get a score of 150000. It will give you 75 XP and at least ten Coin so once you do this three or four times you level up and get forty Coin, and add that to the thirty or fourth Coin you already have from doing this three or four times and you get around 90-100 Coin in about half and hour to and hour of gameplay.
