Played this game for a year nearly and all I'll say is the costs are astronomical! The takes the biscuit out of free to play. And today they even advertised a pack that they made a mistake on, causing 100s to buy it, and then they simply took the pack contents back without a fair refund. After spending an insane amount of money on what is just a game on my phone, I will never spend another penny. They should not be able to bait and change advertised sales.
