1. Go to settings

2. Click about tablet/ phone

3. Click android version many times .

Then you will go to your home screen automatically and a picture of your android version like lollipop , Oreo etc will come

4. Then click it one time and don't release your finger

5. Then you will enter the secret game ( some are pretty boring)

Hope it works,

If it works comment on my wall and if you want you can tell what game you got :)
