This trick to cheat at basketball or football on Facebook Messenger works thanks to GameGuardian, a kind of GameHacker but a little better I think!
First of all, know that the hack method presented in order to cheat on Messenger is in no way dangerous for your account, Facebook has other things to do than check poor scores on a game between friends so don't worry!
To perform this trick you will need the rights root on your Android device, for people with a device Samsung I invite you to watch the video available in the required elements section further down on this page in order to root your smartphone or tablet very simply. For other brands I invite you to do your own research on Google.
You will then need to download GameGuardian (available further down the page in required items) on the official website, being a hack application it is no longer available on the Google PlayStore. You can download the application directly from your mobile. Once the file .apk downloaded, make sure to allow installations from unknown sources as shown in video then install GameGuardian.
All you have to do is click on the GameGuardian shortcut, give it root rights and finally click on " To start up » . Now follow the instructions in the video to finally change your score to the one of your choice. If you miss a manipulation (a basket for example), simply throw the ball again to get the required score: for example, to go from 2 to 3 points, you miss and return to 0, you just need to throw 3 balls into the basket before continuing the manipulation on GameGuardian, no need to start all over again.
