I installed this game in 3gb ram phone and believe after installing this game my phone started lagging it was because of its memory size, after installing its not over this game asks you to to be connected to the WiFi as to play this game you need further more games data which has to be installed, After installing this game and all its data I found that my phone was literally slower than before, than again I unistalled this game and cleard all of its additional data than my phones speed was restoredSo I will not recommend this game for 3gb ram devices, well if your phone has 4gb or 6gb than you can proceed.
