Game Matrix / Game Payoff Matrix
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
A game matrix is a table in which each player's strategies form one axis and each cell records the payoffs for that combination of choices. Its value is that an interactive problem which is hard to hold in the head becomes a single visible object, and the standard questions, dominant strategies, best responses, and equilibria, become table lookups rather than arguments.
SCAFFOLDING EFFECT
Reduce cognitive load
- Fill the grid: put each player's strategies on an axis and the payoffs in the cells. - Read rows and columns: look for any strategy that beats every alternative. - Find the stable cell: the combination no one wants to leave alone.
Anchor fast decisions
Interaction is hard to reason about because each outcome depends on two choices at once. Placing all combinations side by side externalizes that dependency, so the eye can scan for dominance and stability instead of the mind having to track the pairings in working memory.
