- I used to manage a game, for group compettition, playing similar to "20 questions" game, sir.
- The purpose of the game was to practice each group how to make appropriate yes/know questions respectively leadiing to guess the right answer. As your point, the winning strategy is to divide the set of possible questions into smaller and smaller sets, respectively.
- For example; When the game leader says,"it is a thing", the questions made by Group A should be : 1) Is it in a house.? (Yes.) 2) Do we usually see it in the living room? (N0.) 3) Do we usually see it in the kitchen? (Yes.) 4) Is it mostly made of wood? (Yes.) 5). Do people use the thing in pair. (Yes.) Do chineses use it when they have a meal. (Yes.) Then, the answer is "chopstics." The game leader says, "Congratulatin! You've got it."
