## What it is
The Evolution of Trust is an interactive, playable guide to the game theory of cooperation, built as a browser-based web experience with JavaScript. It teaches concepts like the iterated Prisoner's Dilemma through animated simulations and explanations.

## Use cases
- learn game theory of cooperation interactively
- teach students about the iterated prisoner's dilemma
- explore how trust evolves in repeated games
- find an example of an interactive educational web explainer
- study strategies like tit-for-tat and grim trigger
- use a public-domain educational resource in a classroom

## When to choose
- you want an engaging, interactive way to learn or teach cooperation and game theory
- you need a CC0/public-domain educational resource you can freely reuse or translate

## When to avoid
- you need a rigorous academic treatment or formal proofs of game theory
- you need a reusable game theory library or engine rather than a self-contained explainer

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: game-engine, data-visualization, animation
- domain: education, tutorials
- platform: browser
- tags: interactive-explainer, game-theory, cooperation, prisoners-dilemma, simulation, public-domain, game-development, web-server, javascript
