A spoken game like 20 Questions. Created by youtube's SharkeyeJones.
The rules are simple.
1. The Guesser is given 81 tries to guess what you're thinking. No questions other than to guess.
2. The Guesser must have knowledge as to what you're thinking or conceivably be able to guess it.
3. If the Guesser correctly guesses, you must take them out for a meal.
Tom has to pay for my meal because I beat him in 81 Guesses.
