A lot of people play this game indoors because it is cold outside. But, actually, you can play this game anywhere. If you play this game with your family, you will most probably play this game in the living room or on the porch. If you play this with a large group of people, like with the whole employees at work, you can play this game in the office or in a medium hall. Children who attend Church play this game while in Sunday School in the Church Hall. If you live far away from your parents, don't worry, just invite your roommates and probably classmate to play this game, and trust some of them to keep the answers.
Yes, it is important to not let anyone see the answers to this game. You can keep them on your phone. Just lock it with a password and fingerprint. If you write the questions and answers, you can keep the file on your laptop and hide it in a special folder. You can also hide the printed ones in your pocket or your friend's. You might as well just hide the answer for the chosen contestant, so she/he will guest the answer. In this case, you just show the answer to the rest of the players.
Teenagers must have been planning for this party a long time before Christmas. Since they do this after having a party with their families, they probably need more ideas on how to make the party more lively. They can play a guessing game, where they have to feel what's in the stocking. Another guessing game they can do is guessing the title of a carol by mimicking the title. If a movie night is on their list, they can play Christmas movie trivia or any other question and answer game around Christmas. Does it sound amusing already?
Some people might not celebrate Christmas with their family because of many reasons. But, worry not, because you can still enjoy the day with yourself. You can buy and unwrap the gift yourself. You can hunt for it prior to Christmas. If you still have extra energy, you can get a part-time job, take an extra shift at work, or volunteer in a dog shelter. This holiday is also a great day for you to clean the apartment thoroughly and be generous to each other by giving out leftovers or any products to those who need them.
