You need an internet device to play this. Your Xbox One controller won't help you with this game.
Also, the achievement may not pop in-game. You should notice that it's popped when you look at the achievement app on the dashboard. I don't know if you have to wait until after the game or if it works during the game. (I've been told that it shows up during the game.)
You have to have at least two players... you can get around this by opening two browsers like Chrome, IE, Firefox, etc. Yes, it works, and it's easier than cache-clearing, etc.
In a group of players, have everyone put in nonsense letters, or the same thing. The truth will not be one of those (unless someone magically DID put in the truth, in which case that person should tell the group). Since it's obvious which is not the fake answer, have everyone select that one.
The game will always have at least 4 answers, so in order to get this more easily, have 3+ players, but even with 2, you can probably guess the right one eventually if you coordinate.
