Diplomacy is a game which is easy to learn but impossible to master. The rules are all very intuitive; lots of people pick them up just by playing, but this document will familiarize you more quickly.

RR - Points - Objective - Units - Moves - Rules - Play

webDiplomacy, as a community, is a competitive and fun place to play. Currently we have two site supported ranking systems.

RR

The first is our “Reliability Rating” (RR); this ranking is determined based on how often you fail to enter moves in a turn (NMR/No Moves Received) or leave a game before it’s conclusion (CD/Civil Disorder). Most tournaments, special rules games, or high stakes games have RR restrictions; meaning if you leave games often or irresponsibly forget to enter moves frequently you may find it hard to join competitive games.





Points

The second system is our point system ( ), which is used to determine how many games you can join and what stakes the game will be. You start with 100 and are reimbursed whenever a loss of points results in you having less than 100 . Points are fun and provide a tangible reward for winning but are far less important to your ability to play fun and enthralling games on webDiplomacy. Many of our tournaments are unranked, and those that aren’t are usually willing to play at lower levels for players with very high Reliability Ratings.





Objective

The objective of Diplomacy is to be the first to get 18 supply centers. For each supply center you occupy you get a new unit, and you lose a unit whenever a supply center you own gets occupied by someone else.



You can recognize the supply centers with the markers which are placed on them.

Units

Army

This unit can only move on land.

Fleet

This unit can only move in the sea, and in coastal territories. It can also convoy armies across sea territories using the convoy move.

Moves

Hold

The unit will defend if its territory is attacked, but otherwise do nothing.

Move

The unit tries to move into (also known as attacking) an adjacent territory.

Support hold, support move

Support is what Diplomacy is all about. As no one unit is stronger than another you need to combine the strength of multiple units to attack other territories.

You can use fleets to carry army units across sea territories, this is called a convoy. You can also string multiple convoys together to move an army unit large distances overseas in a single turn.

Rules

In diplomacy no army or fleet is stronger than another, and a holding unit will always beat a moving unit of equal support.
