Turns over daysAgainst the computer

webDiplomacy

The board game Diplomacy, played online. Seven powers share Europe in 1901, everyone writes orders in secret and the turn resolves at once. Most games move one phase a day, so a game takes weeks.

Facts

Made by
Kestas Kuliukas and volunteer developers, country not stated
Running since
Its open-source code has been on GitHub since September 2011. The site's own start date is not published.
Setting
Europe in 1901, from the board game Diplomacy
Format
Turn-based: all seven players write orders in secret, and every move resolves at once when the phase ends. No dice.
One game lasts
Weeks to months at one phase a day (est.)
Check in
Once a day in most games (est., from '1 day /phase' in the live game list)
Players
7 on the classic map; you win by holding 18 supply centres
Phone
No app. The site has a phone layout, with a link to switch to desktop mode.
Account
None for a game against six AI players. Games against people need a free account.
Money
Nothing for sale. Donations only, and the donations page says no feature is locked behind a paywall. An advert banner sat above the board on 23 October 2026; a note from 2 June 2025 says the site is looking for ways to pay its costs.
Paid random items
None. Nothing is sold and Diplomacy has no dice. Joining a game costs free ranking points that the site calls a 'bet', paid into a 'pot'. Points cannot be bought, and anyone who drops below 100 is topped back up to 100.
Chat
Messages between players, called press, are the heart of the game; there are also private messages and a forum. Gunboat games turn messaging off. The rules ban abusive or degrading content and a moderator team enforces them. The site has shared anonymised player messages with research groups for AI training, under NDA.
Age
No age rule on the rules or registration pages. The rules include guidelines for teachers who run games for students. It has no app and so no PEGI rating.

How it plays

How webDiplomacy plays

webDiplomacy plays the board game Diplomacy on a map of Europe in 1901, and each player runs one of seven powers. On 23 October 2026 the site listed 427 active games and 429,368 registered players.

A phase works like this: everyone writes orders, the deadline passes, and all moves resolve together. Games in the live list run on phases such as '1 day /phase', and each game year has a spring and an autumn, so most games take weeks or months (est.).

You win by holding 18 supply centres. With no dice, deals between players decide most games, so the messages matter more here than in any other game on this list.

A no-account game against six AI opponents starts from the home page. Ours made us England in Spring 1901, with 23 hours 59 minutes to enter orders.

Your first game

  1. Step 1
    On webdiplomacy.net, start a game against AI opponents. No account is needed.
  2. Step 2
    Give an order to each of your units on the map before the phase deadline.
  3. Step 3
    Make a free account to play people, and pick a game whose phase length suits you.
  4. Step 4
    Try a gunboat game, with no messaging, if you want the strategy without the negotiation.

Money, chat and age

webDiplomacy sells nothing and asks for donations. An advert banner now appears, after a June 2025 note that funding had to change. Joining a game uses free ranking points with betting words ('bet', 'pot'); they cost nothing, cannot be bought and refill to 100.

Talking is the game: players write to each other to make and break deals. The rules ban abusive and degrading messages, moderators enforce them, and gunboat games remove messaging. The site says it has shared anonymised, redacted messages with research groups to train AI, under NDA.

We found no minimum age. The rules have a section for teachers running games with students. There is no app and no PEGI rating.

Good for

Players who enjoy negotiation, one short visit a day, and a game with no luck and nothing for sale.

Harder for

Anyone who cannot check in daily: missed turns lower your reliability rating. Players who dislike being lied to by other players.
