Don't play this game it is money grabbing app ,poor graphics lame gameplay, no strategy at all ,simply player with bigger wallet wins ,every single thing is very expensive ,if you want to free play forget it it will take months to upgrade anything , Alliance features are non existent, there is no resources trade with your alliance members ,you have no idea when their bases get attacked,so you can warn them or lend assistance unless someone have time to sit whole day and watch the grass grow .It gets better with time now after about 4 years wasted time they got even greedier merging servers , destroying players lost time and money , I never have seen such disrespect and total disregard to the people who make them money , you are worst stinking game developer in the whole market and I know this as I played hundreds of games and spend fortune on them but I hope people will stop pumping your corrupted company , which has total disregard to players .
