gonna uninstall the app, this app is very not considerate to those who buy coins, the lucky number game has less chance of multiplying your coins, i bought 300 coins and wanted to expand it through lucky number but it's just impossible to win and just lost my coins for just a few minutes always x1 and lose. very not considerate, calls are very expensive and lucky number is useless.. $2 for 2 mins of call.. not a friendly app at all.
