Here’s a tutorial I made on YouTube for Gameflip. There’s a few mistakes on the text and also in the transition of the video (I’m a newbie making videos, that’s my first tutorial/explanation video about an app) , but it has been of help for some people in the process of registration and to understand quickly how the gameflip system works and how inviting friends will get you an amazing advantage.
It only has 300 views, but I’m confident it’ll reach more views eventually.
