Diplomacy is the brutal board game where seven players sit around a map of Europe, spend six to twelve hours negotiating alliances and writing secret orders, and walk away either as lifelong friends or sworn enemies—no dice, no luck, just trust that someone will break.

How do you play the game Diplomacy?
Diplomacy drops you onto a map of Europe just before World War I, controlling one of seven great powers: Austria, England, France, Germany, Italy, Russia, or Turkey. Each power starts with a handful of armies and fleets positioned across the continent, and every player’s goal is the same—control 18 of the map’s 34 supply centers to win. No dice, no cards, no luck. Just pure strategic negotiation and order-writing.
Setting up the board and powers
The classic map divides Europe into land provinces and coastal sea spaces, with 34 supply centers scattered strategically across the territory. Renegade Games Studios (current publisher of the official rules) confirms that no single power starts strong enough to eliminate another player alone—this isn’t a design flaw, it’s the point. You need allies, or at least the illusion of them.
- Each player receives orders secretly, writing them on order sheets
- All orders are revealed simultaneously when the phase resolves
- Negotiation between players is allowed at any time, including during play
Understanding the turn structure
Games begin in 1901 and advance year by year. Each game year contains two movement phases—Spring and Fall—followed by a Winter adjustment phase. Units move during Spring and Fall, but ownership of supply centers only changes at the end of Fall. In Winter, players build new units (if they have captured a new supply center) or remove units (if they’ve lost centers) to match their unit count to their supply center count.
Orders follow a specific syntax: Unit Type + Province + Order Type + Target. Support orders are commonly taught with the mnemonic “X supports Y to Z,” meaning one unit names another friendly unit and the territory it should move toward. Convoys allow armies to cross sea spaces, and convoy chains can be linked together for longer routes.
Negotiation and alliance rules
Diplomacy makes opening negotiation a formal part of the Spring turn. Players are encouraged to talk, make deals, and form alliances—but those deals have no mechanical enforcement. The Renegade Games Studios quick start rules emphasize that trust is central to play, and there’s nothing stopping an ally from stabbing you the moment it becomes advantageous.
“Diplomacy is ultimately a game about building trust.” — Renegade Games Studios (official rulebook publisher)
Resolving conflicts and retreats
When multiple units move to the same territory, the conflict resolves based on strength. A unit with support outvotes one without. If a unit is attacked while also receiving support from elsewhere, the support may be cut if the supporting unit is attacked in turn. This cascading logic means a single poorly-planned order can unravel an entire alliance structure.
Retreating is possible but limited—if your unit is forced out of a territory and has no valid retreat space, it’s disbanded. The game also allows for draws: if all surviving players mutually agree, or if a turn/time limit is reached, the game can end in a collective victory rather than a solo win.
Beginner guides sometimes cite 17 supply centers as the winning threshold, but this conflicts with the official rules stating 18. The discrepancy likely stems from alternate rule variants or community house rules—always check which version your group is using.
Is Diplomacy a good board game?
BoardGameGeek users have rated Diplomacy at 7.0/10 consistently over the years, placing it among respected strategy games despite its age. But “good” depends heavily on what you’re looking for. If you want dice rolls, hidden information, or a quick game, Diplomacy will frustrate you. If you want a pure test of negotiation skill and strategic foresight, it remains unmatched.
What players praise about Diplomacy
- Entirely player-driven outcomes—no luck element means every result reflects someone’s decision
- Deep social dynamics that create memorable stories and (sometimes) lasting grudges
- Extraordinary replay value since no two games unfold the same way
- A focus on the seven players around the board rather than board control alone (Play Diplomacy Online)
Common criticisms of Diplomacy
- Games routinely stretch to 6–12 hours for face-to-face play
- The social dynamics can cause real-life tension between friends and family
- New players often struggle with the simultaneous order resolution system
- Requires exactly 7 players for the standard game—no good way to scale down
Who should play Diplomacy
Diplomacy suits players who enjoy extended strategy games and can separate in-game negotiation from personal feelings. It’s famously been called a “friendship-ending game,” which speaks to how seriously players take the experience. Groups seeking light entertainment should look elsewhere; those who want to test their social strategy chops will find nothing quite like it.
The game has no luck element, which means every outcome is player-driven. This makes Diplomacy ideal for groups that want skill-based competition rather than chance-based excitement.
How long is a Diplomacy game?
A standard face-to-face Diplomacy game takes 6–12 hours, making it a genuine commitment rather than a casual evening activity. The game ends when one player controls 18 supply centers, but game length depends heavily on player skill, negotiation speed, and how quickly alliances form or collapse.
Average play time for face-to-face games
Most face-to-face games complete in a single session lasting from early afternoon well into the evening. Some dedicated groups spread play across multiple sessions, meeting weekly to continue an ongoing game. The Renegade Games Studios quick start rules note that a predetermined turn limit (such as 1907) can end a game early if all players agree.
Online game duration
Online platforms like webDiplomacy allow games to run asynchronously over weeks or months, with players submitting orders on their own schedules. This makes Diplomacy accessible to people who can’t dedicate a full day to a single game. webDiplomacy also hosts variant formats—the “chaos” variant uses 34 players, each controlling a single supply center on the standard map, starting in Winter 1900.
Factors that affect game length
Experienced players resolve orders faster and negotiate more efficiently, cutting game time significantly. Early betrayals can trigger cascade eliminations that shorten games, while balanced mid-game alliances tend to extend play. Draw agreements—where remaining players split victory—sometimes end stalled games earlier than reaching 18 centers.
What was JFK’s favorite game?
John F. Kennedy reportedly enjoyed playing Diplomacy, and this connection has contributed significantly to the game’s prestige over the decades. The 35th President of the United States allegedly played the game during his time at Harvard, where he developed friendships with future advisors who also participated in games.
John F. Kennedy and Diplomacy
Kennedy’s interest in Diplomacy reportedly predates his political career, placing him among the game’s most notable players. Wikipedia notes that the game was popular among political and military strategists, which may explain why Kennedy found it appealing—Diplomacy simulates exactly the kind of alliance-building, betrayal, and strategic positioning that characterized Cold War geopolitics.
Historical anecdotes about JFK playing Diplomacy
Multiple sources confirm Kennedy played Diplomacy, though precise details about frequency, opponents, and outcomes remain undocumented. What matters for our purposes is the signal: a president who would later navigate the Cuban Missile Crisis found value in a board game that simulates exactly the kind of high-stakes negotiation and calculated trust he would face in office.
Kennedy’s endorsement—even informal—placed Diplomacy in elite company among strategy games. When a future president recommends your hobby, it tends to attract attention from historians, journalists, and curious players alike.
What is the hardest board game of all time?
Diplomacy frequently appears on lists of the hardest board games, though “hardest” is inherently subjective. What makes Diplomacy particularly demanding isn’t any single mechanical complexity—it’s the combination of pure strategy with zero luck, extended play sessions, and the social skill required to negotiate effectively while watching for betrayal.
Why Diplomacy is considered one of the hardest
- No luck element means every failure traces back to a decision you or an ally made
- The simultaneous order system punishes miscommunication between allied players
- Social manipulation and trust management require skills that many strategy games don’t even engage
- Extended play sessions demand sustained strategic focus over 6–12 hours
Other contenders for hardest board game
Diplomacy shares “hardest game” territory with titles like Chess, Go, and various war simulations. Chess demands deep calculation; Go requires pattern recognition across a vast board; war games demand logistical planning. Diplomacy’s unique contribution to difficulty is social—it asks players to build trust while planning its betrayal, sometimes from the very first move.
The same qualities that make Diplomacy hard—length, social intensity, zero luck—also explain why players who love it describe it as the most rewarding strategy experience they’ve had. Difficulty here isn’t a bug; it’s the feature.
Upsides
- Pure skill-based competition with no dice or random elements
- Deep social dynamics create genuinely memorable gaming experiences
- Exceptional replay value—no two games play the same
- Accessible online through webDiplomacy and PlayDiplomacy
- Distinguished player history includes political leaders and strategists
Downsides
- Requires exactly 7 players for standard play—difficult to organize
- 6–12 hour commitment excludes casual gaming sessions
- Social dynamics can cause real-life conflict between players
- Steep learning curve for order syntax and resolution logic
- Beginner guides sometimes contain conflicting rules information
Diplomacy Specifications
Six game elements, one pattern: everything in Diplomacy serves the core promise of pure player-driven competition.
| Specification | Value | Notes |
|---|---|---|
| Standard player count | 7 | One power per player; no solo mode |
| Victory threshold | 18 supply centers | Of 34 total on standard map |
| Starting year | 1901 | Pre-WWI Europe setting |
| Turn structure | Spring → Fall → Winter | Supply changes resolve end of Fall |
| Unit types | Army, Fleet | Armies move on land; fleets on sea/coast |
| Support syntax | X supports Y to Z | Mnemonic for teaching order writing |
| Max variants documented | Multiple commercially published | Machiavelli, Kamakura, Colonial Diplomacy, others |
| Online chaos variant | 34 players | webDiplomacy variant; each controls 1 supply center |
The implication: even the structural constraints (exactly 7 players, no luck) reflect a deliberate design philosophy prioritizing human negotiation over mechanical randomness. The chaos variant’s departure to 34 players shows how the community has adapted the format while preserving that core identity.

Frequently asked questions
Can Diplomacy be played with fewer than 7 players?
The standard game requires exactly 7 players, one for each great power. However, online platforms like webDiplomacy offer variants including the “chaos” format (34 players, each controlling one supply center) that work with more players. Some groups also use informal solo rules or bots to fill empty seats, though these aren’t official.
What is the best power to play in Diplomacy?
There is no objectively “best” power—each has strategic strengths and vulnerabilities. Austria and Italy are often considered more difficult due to their surrounded positions, while England and France have natural geographic protection. Power choice typically depends on player experience and preferred playstyle rather than mathematical advantage.
How do you win a Diplomacy game?
Win by controlling 18 of the map’s 34 supply centers at the end of a Fall turn, according to the official rules. Alternatively, a game can end in a draw if all surviving players mutually agree, or if a predetermined turn limit (such as 1907) is reached and players accept the outcome.
Is Diplomacy suitable for beginners?
Diplomacy has a steep learning curve, particularly around order syntax and simultaneous resolution. However, beginner-friendly resources like the Joar von Arndt beginner guide explain core mechanics clearly, and online platforms often have experienced players willing to mentor newcomers. First-time players should expect to make mistakes—they’re part of the learning process.
What is the difference between Diplomacy and Risk?
Risk is a dice-based conquest game where random outcomes determine battles, and hidden mission cards provide objectives. Diplomacy has no luck element—every outcome is determined by order resolution and player negotiation. Diplomacy also emphasizes alliance-building and betrayal mechanics that Risk doesn’t include, and games typically last much longer.
Are there any official Diplomacy tournaments?
The hobby community organizes tournaments, though there is no single official governing body like chess has. Events occur at board game conventions and through online platforms. The Diplomacy database at webDiplomacy tracks tournament results and player ratings for competitive formats.
What is the best online platform for Diplomacy?
webDiplomacy (webdiplomacy.net) and PlayDiplomacy (playdiplomacy.com) are the two most established online platforms. webDiplomacy offers the chaos variant and asynchronous play, while both platforms provide beginner guides and community support. Choice between them often depends on preferred game pace and community culture.
Where can I buy the physical Diplomacy board game?
The standard Diplomacy game is published by Avalon Hill (a subsidiary of Renegade Games Studios). Physical copies are available through board game retailers, Amazon, and the publisher’s website. Digital versions and print-and-play variants are also available through various hobby channels.
For strategy game enthusiasts ready to commit the time and social energy, Diplomacy remains one of the most distinctive experiences in tabletop gaming. The question isn’t whether it’s good—it’s whether you’re prepared for what “good” means here: six to twelve hours of calculated trust, tactical betrayal, and the occasional friendship that survives the experience.
