Objective: The objective of Diplomacy is to control the majority of supply centers on the map, which typically means controlling 18 out of 34. This is achieved through negotiation, alliances, and strategic movement of armies and fleets.

Components:

• Game board (map of Europe)

• Army and Fleet pieces (for each player)

• Supply center markers

3. Supply Centers:

   • Supply centers are marked on the board and are key to controlling the game.
     

Gameplay:

1. Game Phases:

   • Diplomatic Phase:

     • Players negotiate and form alliances or make agreements.

     • Diplomacy is a core element, and players can talk freely with each other to discuss strategies.

   • Order Writing Phase:

     • Players write down their orders secretly. Each player submits orders for their armies and fleets.

     • Orders include moving to an adjacent territory, supporting an attack, or holding a position.

   • Order Resolution Phase:

     • Orders are revealed and resolved in a specific sequence (e.g., moves, supports, and retreats).

     • Conflicts are resolved based on the strength of the units involved and the support provided.

   • Adjustment Phase:

     • Players adjust their units based on the number of supply centers they control.

     • Players with more supply centers can build additional units, while those with fewer may need to disband units.

2. Types of Orders:

   • Move: Move a unit from one territory to another.

   • Support: Assist another unit's move or attack.

   • Hold: Keep a unit in its current position.

   • Convoy: Allow an army to move across water via fleets.

3. Conflict Resolution:

   • When two units move into the same territory, the outcome depends on the strength of the attacking and defending units.

   • The player with more support and stronger units typically wins.

4. Winning the Game:

   • The game ends when a player controls the majority of the supply centers, typically 18 out of 34.

   • Alternatively, the game may end if a player is eliminated and the remaining players agree on a resolution.
     

Strategies:

• Diplomacy: Effective negotiation and forming alliances are crucial.

• Strategic Movement: Plan your moves considering potential alliances and rival actions.

• Deception: Use deception to mislead other players about your true intentions.

• Adaptation: Be ready to adapt your strategy based on the changing dynamics of the game.
  

Special Rules:

1. Neutral Territories:

   • Some territories are neutral and may be occupied by units from any player.

2. Alliances:

   • Alliances are not binding and can be broken at any time. Trust and betrayal are integral to the game.
