Why this matters

Before any payoff matrix, a game is just three things: players, the moves each can make, and the outcomes those moves produce. Once you can name all three for a situation in front of you, you've already done the hard part — most real-world 'games' go wrong because someone left out a player, forgot a move, or mis-stated what success even looks like. This lesson is about slowing down at that step.

Demo

A formal game in normal form is a triple $(N, S, u)$ . Players, strategies, payoffs. Every game you'll meet in the course is some flavor of this:

G = \langle N,\; \{S_i\}_{i \in N},\; \{u_i\}_{i \in N} \rangle
