As a developer for all mobile platforms, I can tell you with absolute certainty that it is impossible to simply copy and paste an android game onto your windows phone. It is guaranteed to be a scam. Windows phone simply does not physically have the components in the OS to allow many features of complex Android games, as Microsoft enforces the use of their own methods and solutions. That makes it extremely difficult to port games that use technology involving networking, multiplayer, and server/client interactions. Windows phone also is not physically capable of reading, writing, sending, and storing data the same way that Android games do.
I use the same development environment software that Pokemon Go was created with, so I can tell you absolute certainty. Anyone claiming you can load an APK of Go onto your phone is scamming you and you WILL get some bad software onto your phone.
