You can play the game, titled Say The Same Thing, with one of your friends or with a randomly chosen player. (If you sign up now, you can also participate in a temporary promotion where people are randomly selected to play with a band member.) Each player types in a word, then you see what the other player said, and you use that as prompt for another word. As the game’s title implies, you win when each of you enters the same word.
It helps if you understand the other player’s interests. For example, I was playing with Graphicly‘s Micah Baldwin — after several rounds, I entered “Perry White,” he entered “Smallville,” and we won by both entering “Lana Lang.”
