To connect two devices you'll need internet access, you don't needto be in the same room, even in the same country, but you will needto activate your Google Play Game account in both devices, you haveinstructions inside the game. To make the prank you need twodevices, one to control and one to show the pencils, then use thepower of suggestion and the pencils will start moving withoutanyone touching them, except when you are going to need to resetthe pencils, and this might seem spooky in the right setting,answer the questions right to make the mood, and then show Charlie.This is how the real game, the Charlie Charlie Challenge works,players balance one horizontally aligned pencil on top of avertically aligned pencil (essentially, in the shape of a cross).Both writing utensils sit atop a piece of paper divided into fourquadrants. Two of the quadrants are labeled "yes" and two arelabeled "no." Players then invite a spirit, Charlie, to play withthem.
