Just another scam out there. 'coins' cannot be redeemed for the gift cards as the gift cards are always 'sold out'. Added 'trophies' and 'piggy heist' nonsense as a further distraction. Lame. Clearly a scam. There apparently is no policing or enforcement on behalf of Google play store to remove scam garbage apps like this and so many others from their catalog. Shame on all parties involved in perpetrating this fraud.
