Payoff Matrix

• $N$ - dimensional → $N$ … number of players
• $m\times m$ matrix → $m$ … number of strategies of players
  • square if all players have same (number of) strategies
• Rock-Paper-Scissors with 2 players
  • 2-dimensional matrix. 3x3 (rock, paper, scissors are the strategies of both players)

Sequential Payoff Matrix

• putting in full strategies, not just choices
  • Example Color Competition
• Experiment 5 GT1 has a very nice payoff matrix

Payoff vs Outcome

• payoff … individual value
• outcome … grouping of payoff combinations
