The other players are the “questioners. " Once decided, the answerer should not tell anyone what the objective is. Keep the number of players between 2 and 5 for best results.

Sample questions: “Is it a mammal?” or “Is it bigger than a basketball?” or “Can you walk on it?” Any question that helps the players determine the objective can be asked.

Each round takes approximately 5 minutes. If no one guesses the right answer after 20 questions are asked, the answerer should reveal the answer to the players before moving on to the next round.

Example 1: 8. Example 2: 43.

Example 1: 8 x 2 = 16 + 10 = 26. Example 2: 43 x 2 = 86 + 10 = 96.

Example 1: 26 / 2 = 14. Example 2: 96 / 2 = 48.

Example 1: 14 – 9 = 5. Example 2: 48 – 43 = 5. Respond with, “Is your secret number 5?”

Example 1: Born in 1981. So 81 + 35 (age) = 116. Example 2: Born in 1999. So 99 + 17 (age) = 116.

Example: The birth year is 2003, so the last 2 digits of the year are 03. If the person adds the age they’ll be at the end of the year to that number, it will always be 16. In this case, a person born in 2003 is 13 years old. 03 + 13 = 16. Note that the invariable answer depends on the current year. In the year 2017, the answer will always be 117 (17 if born in or after 2000). In 2018 the answer will always be 118 (or 18), and so on. [4] X Research source

The people who are overly eager to participate are usually just seeking attention for themselves. You don’t want to perform with someone who is trying to upstage you. The very shy people don’t want to be involved and are generally not very enjoyable to perform with.

Being able to read body language is a useful skill to have when you’re playing other kinds of games, too. For example, card games. Good posture and standing up straight communicates confidence and alertness; slouching indicates shyness, sadness or a lack of confidence. Pay attention to your own body language as well. Stand up straight and look the person directly in the eye. Avoid fidgeting.

Control your facial muscles as much as you can so that you won’t give anything away. This skill is also very useful for card games. Avoid making any extra facial movements, such as eye rolling, that can communicate negativity and judgement.
