the device requirement is not just how large your ram is, but also CPU, the operating system and so on. you can check them in the editor note or in the detailed info~

I have 3 gb ram and 32 gb memory but it works

i uae huawei p20lite 4/64. it says it was not available for download in google play using my device, so i tried downloading it using my other phone and transfer the apk and obb to my huawei. it works but the lag was unbearable. cant even walk hahah but using my other phone, it was smooth
