The best games are not those in which all goes smoothly and steadily towards a certain conclusion, but those in which the outcome is always in doubt. Similarly, the geometry of life is designed to keep us at the point of maximum tension between certainty and uncertainty, order and choas. Every important call is a close one. We survive and evolve by the skin of our teeth. We really wouldnt want it any other way.

Set of players : Who is playing 2. Strategy s pace of each player: How they can play 3. Payoff each player receives given any s trategy profile: What they will win given each combination of their strategy and their opponents strategies. GroupClicker Question (P): Everyone is going to click a number between 1 and 9, trying to guess the number that is closest to 2/3 of the class average. For instance, if students click 2, 3, 6, and 9, the average will be (2+3+6+9)/4=5 and the winner will be the student who clicked 3, since it is closest to (2/3)*5=3.33. 1 2 3 4 5 6 7 8 9 0% 0% 0% 0% 0% 0% 0% 0% 0% 1. 1 2. 2 3. 3 4. 4 5. 5 6. 6 7. 7 8. 8 9. 9 14 Class 23  Game Theory Fundamentals Normal Form Game 1.
