but Its not apk file, it's .rar
I don't think that you can install that on android
.rar needs to be extracted. It contains the Apk in it.
If your Phone does not offer an Extract option for the .rar Folder please follow these steps to extract the .rar
Follow the below instructions to open a RAR file on your Android device:
- Download and install the RAR app for Android.
- Open the RAR app. ...
- Navigate to the folder containing the file you wish to open. ...
- Tap the RAR file and view the contents. ...
- Tap the individual files to open them.
This is I believe the easiest way for you to open the .rar Folder. Once you have extracted the Apk out of the .rar Folder, you can install and play it.

This is the .RAR app, as mentioned in the previous comment.
