You will need two players for this game. When it is your turn to answer, after both players have seen the question, the other player will look away while the you answers by typing 1 or 2 as their choice. Then, the other player will try to guess which answer you chose (also by typing 1 or 2). If he/she gets it correct, he/she will get a point.
Please share any new ideas for questions in the comments!
