+# Snatch or Share - Game Logic
+
+## Game Overview
+Snatch or Share is a multiplayer game that simulates governance evolution in decentralized exchanges, based on Elinor Ostrom's "Snatch Game".
+
+## Game State Structure
+
+### Main Game State
+```typescript
+GameState {
+  round: number (1-5)
+  groups: Group[] // Groups of 3 players
+  currentPhase: 'waiting' | 'trading' | 'judging' | 'results'
+}
+
+Group {
+  id: string
+  players: Player[3]
+  currentJudge?: Player // Only in Round 5
+  activeTradeOffers: TradeOffer[] // Multiple simultaneous offers
+}
+
+Player {
+  id: string
+  name: string
+  producerRole: 'turkey' | 'coffee' | 'corn'
+  tokens: {
+    turkey: number
+    coffee: number
+    corn: number
+  }
+  points: number // Calculated: own_tokens * 1 + other_tokens * 2
+  shameTokens: number // For Round 4
+  isSuspended: boolean // For Round 5
+  role: 'trader' | 'judge' // Only relevant in Round 5
+}
+
+TradeOffer {
+  id: string
+  offererId: string
+  targetId: string
+  offering: { turkey: number, coffee: number, corn: number }
+  requesting: { turkey: number, coffee: number, corn: number }
+  status: 'pending' | 'accepted' | 'rejected' | 'snatched' | 'cancelled'
+}
+```
+
+## Game Initialization
+
+### Room Configuration
+- **Exactly 3 players required** to start the game
+- **Maximum 3 players** per room
+
+### Producer Role Assignment
+- Each player is randomly assigned **one unique producer role**:
+  - **Turkey Producer**: Starts with 5 turkey tokens
+  - **Coffee Producer**: Starts with 5 coffee tokens  
+  - **Corn Producer**: Starts with 5 corn tokens
+- **Roles cannot be repeated** - exactly one producer of each type per game
+
+### Judge Role (Round 5)
+- In Round 5, one player becomes **Judge** (rotates each round)
+- **Judge role is decorative** - player keeps their original producer role
+- Judge has additional responsibilities but maintains their trading capabilities
+
+## Round Flow (Focus: Round 1)
+
+### Round 1: State of Nature
+- **No time limits** on turns
+- **Simultaneous trading**: All players can make offers at the same time
+- **Offer limit**: Each player can make maximum 2 offers to each opponent
+- **Offer format**: "I give X tokens in exchange for Y tokens"
+- **Offer responses**: Target player can Accept, Reject, or Snatch
+
+### Trading Mechanics
+
+#### Making Offers
+- Players can offer and request **any amount** of tokens (even more than they have)
+- Offers are made simultaneously to multiple players
+- Format: `offering: {turkey: X, coffee: Y, corn: Z}` for `requesting: {turkey: A, coffee: B, corn: C}`
+- **All trade offers are public** - visible to all players in the room, not just offerer and target
+
+#### Resolving Offers
+- **Accept**: Trade executed to the extent possible with available tokens
+- **Reject**: Offer cancelled, no exchange
+- **Snatch**: Receiver gets offered tokens (up to what offerer has) without giving anything in return
+- **Cancel**: Offerer can cancel pending offers
+
+#### Partial Fulfillment
+- All trades execute with available tokens only
+- Example: Offer "6 corn for 6 coffee" but only have 5 corn → Execute "5 corn for 5 coffee"
+- Example: Accept offer for 8 tokens but only have 3 → Give 3 tokens, receive offered amount
+- **No negative consequences** for partial fulfillment - it's part of the game
+
+## Rules by Round
+
+### Round 1-2: State of Nature / Anarchy
+- No special rules
+- All players are Traders
+- No enforcement mechanisms
+
+### Round 3: Counterproductive Rule
+- **Mandatory Rule**: "All trade offers must be accepted"
+- Players still have freedom to snatch
+- Reduces agency, invites exploitation
+
+### Round 4: Soft Norms (Shame Tokens)
+- Each player can assign 1 shame token per round
+- If player starts round with 2+ shame tokens:
+  - Loses 2 tokens before round begins
+  - Barred from offering trades (can only respond)
+
+### Round 5: Governance Rules (Ostrom Adapted)
+- **Group Roles**: Two Traders and One Judge
+- **Judge Role**: Rotates each round
+- **Applied Rules**:
+  - **Position Rule**: Judge oversees fairness and conflict resolution
+  - **Boundary Rule**: Only group members can trade; Judge may suspend rule-breaker for 1 round
+  - **Choice Rule**: Trades are voluntary; Players can report snatching to Judge
+  - **Enforcement Rule**: If Judge confirms snatch → goods returned + snatcher forfeits 3 tokens to victim
+  - **Aggregation Rule**: Trade only completes with explicit mutual consent
+
+## Key Mechanics
+
+### Trading
+- **Exchange Amount**: Always 5 tokens of player's own type
+- **Value System**: own_tokens × 1 + other_tokens × 2
+- **Snatch**: Take opponent's tokens without giving anything in return
+
+### Point Calculation Examples
+- Holding 10 of own = 10 points
+- Holding 5 of own + 5 of other = 15 points  
+- Holding 10 of own + 5 snatched = 20 points
+
+### Governance Evolution
+- **Round 1-2**: No trust → no cooperation → suboptimal outcomes
+- **Round 4**: Social deterrents emerge
+- **Round 5**: Governance stabilizes expectations → trust emerges → optimal outcomes through fair trades

+# 🎯 Snatch or Share - Servidor
+
+Servidor de juego multijugador basado en Colyseus.io que implementa el "Snatch Game" de Elinor Ostrom para estudiar la evolución de instituciones y cooperación.
+
+## 🛠️ Stack Tecnológico
+
+- **Colyseus.io** (framework de servidor multijugador)
+- **Node.js** (runtime)
+- **TypeScript** (tipado estricto)
+- **Express** (servidor HTTP)
+- **@colyseus/schema** (sincronización de estado)
+
+## 🚀 Inicio Rápido
+
+### Prerrequisitos
+- Node.js 18+ 
+- npm 9+
+
+### Instalación y Desarrollo
+
+```bash
+# Instalar dependencias
+npm install
+
+# Iniciar servidor de desarrollo (puerto 2567)
+npm run dev
+
+# Verificar que el servidor esté ejecutándose
+curl http://localhost:2567
+```
+
+### Comandos Disponibles

+npm run dev              # Servidor con hot reload (ts-node-dev)
+
+# Producción
+npm run build           # Compilar TypeScript a JavaScript
+npm run start           # Ejecutar servidor compilado
+
+# Utilidades
+npm test                # Ejecutar tests (placeholder)
+```
+
+## 🏗️ Arquitectura del Servidor
+
+### Estructura de Directorios
+
+```
+server/
+├── src/
+│   ├── rooms/              # Salas de juego Colyseus
+│   │   └── GameRoom.ts     # Sala principal del juego
+│   ├── app.config.ts       # Configuración de Colyseus
+│   └── index.ts           # Punto de entrada del servidor
+├── lib/                   # JavaScript compilado (build)
+└── tsconfig.json          # Configuración TypeScript
+```
+
+### GameRoom.ts - Sala Principal
+
+```typescript
+export class GameRoom extends Room<GameState> {
+  maxClients = 3;
+  private producerRoles = ["turkey", "coffee", "corn"];
+
+  onCreate(options: GameRoomOptions) {
+    // Inicialización de la sala
+  }
+
+  onJoin(client: Client, options: any) {
+    // Manejo de jugadores que se unen
+  }
+
+  onMessage(type: string, callback: Function) {
+    // Handlers de mensajes del cliente
+  }
+}
+```
+
+## 📊 Esquemas de Estado (Colyseus Schema)
+
+### GameState
+Estado principal del juego sincronizado con todos los clientes:
+
+```typescript
+export class GameState extends Schema {
+  @type({ map: Player }) players = new MapSchema<Player>();
+  @type({ array: TradeOffer }) activeTradeOffers = new ArraySchema<TradeOffer>();
+  @type("number") round: number = 1;
+  @type("string") gamePhase: string = "waiting";
+  @type("boolean") gameStarted: boolean = false;
+  @type("number") minPlayers: number = 3;
+  @type("number") maxPlayers: number = 3;
+}
+```
+
+### Player
+Información de cada jugador:
+
+```typescript
+export class Player extends Schema {
+  @type("string") id: string;
+  @type("string") name: string;
+  @type("string") producerRole: string; // "turkey" | "coffee" | "corn"
+  @type(TokenInventory) tokens = new TokenInventory();
+  @type("number") points: number = 0;
+  @type("number") shameTokens: number = 0;
+  @type("boolean") isSuspended: boolean = false;
+  @type("string") role: string = "trader"; // "trader" | "judge"
+}
+```
+
+### TradeOffer
+Ofertas comerciales entre jugadores:
+
+```typescript
+export class TradeOffer extends Schema {
+  @type("string") id: string;
+  @type("string") offererId: string;
+  @type("string") targetId: string;
+  @type(TokenInventory) offering = new TokenInventory();
+  @type(TokenInventory) requesting = new TokenInventory();
+  @type("string") status: string = "pending";
+}
+```
+
+### TokenInventory
+Inventario de tokens por jugador:
+
+```typescript
+export class TokenInventory extends Schema {
+  @type("number") turkey: number = 0;
+  @type("number") coffee: number = 0;
+  @type("number") corn: number = 0;
+}
+```
+
+## 🎮 Lógica del Juego
+
+### Inicialización
+1. **Sala creada**: Espera exactamente 3 jugadores
+2. **Asignación de roles**: Roles únicos asignados aleatoriamente
+3. **Distribución inicial**: 5 tokens del tipo correspondiente
+4. **Fase trading**: Comienza la Ronda 1
+
+### Sistema de Tokens
+- **Valor propio**: 1 punto por token del mismo tipo
+- **Valor ajeno**: 2 puntos por token de otro tipo
+- **Ejemplo**: 5 propios + 3 ajenos = 5×1 + 3×2 = 11 puntos
+
+### Ofertas Comerciales
+- **Límite**: Máximo 2 ofertas por jugador por objetivo
+- **Simultaneidad**: Múltiples ofertas activas
+- **Visibilidad**: Todas las ofertas son públicas
+- **Respuestas**: Accept, Reject, Snatch
+
+### Cumplimiento Parcial
+```typescript
+// Ejemplo: Ofrecer 6 tokens pero solo tener 5
+const actualOffering = {
+  turkey: Math.min(offer.offering.turkey, offerer.tokens.turkey),
+  coffee: Math.min(offer.offering.coffee, offerer.tokens.coffee),
+  corn: Math.min(offer.offering.corn, offerer.tokens.corn)
+};
+```
+
+## 📡 API de Mensajes
+
+### Mensajes del Cliente → Servidor
+
+#### makeOffer
+```typescript
+{
+  targetId: string,
+  offering: { turkey: number, coffee: number, corn: number },
+  requesting: { turkey: number, coffee: number, corn: number }
+}
+```
+
+#### respondToOffer
+```typescript

+  offerId: string,
+  response: "accept" | "reject" | "snatch"
+}
+```
+
+#### cancelOffer
