Bastard company, operated by moronic millennials, constant bugs, problems & errors. Do not start playing this game unless you are prepared to pay thousands of dollars to have ANY hope of completing daily/weekly/monthly or any other challenge. This company is so greedy it sacrifices quality of app & play on a daily basis, this app is fine if you collect & play once a month for a few minutes but you have to be a millionaire to even contemplate doing any kind of challenge on a weekly basis!
