Java Settlers of Catan

Demo Server only: Usually not running.
Click "Practice" to play against AI. No robots are on this server.
Games expire after 90 minutes, use "*ADDTIME*" to extend a game.
If you would like to run your own server, see the Downloads section below.

Play an immigrant on the newly populated island of Catan. Build settlements, roads, and cities by taking commodities from the land around you. Turn a sheep, lumber, rocks and some grain into a settlement, bricks and wood into road, or try to complete other combinations for more advanced buildings and services. Take advantage of trades with other players, or at local seaports to get commodities you might lack. The first player to gain 10 points from a combination of roads, settlements, and special cards wins.

This applet is based on a board game that you can buy from the good people at Mayfair Games.

To play, enter a nickname and then either enter a new name for a game, or double click on a game in the list to join it. Be patient when you join a game, it takes a while to load. If you try to join a game, and there is someone in the game with the same nickname as yours, it won't work. Just enter a new nickname and try again.

Updated 2011-11-01: (1.1.13)

• Game name maximum length is 30, was 20 previously
• Allow player to undo their last bank trade, if the undo is the very next thing they do, by trading the same resources back. For example, give back 1 brick to get back 3 sheep.
• Show your player's total resource count (Rowan idea)
• 6-player board: New game option allows using this board with 2-4 players
• 6-player board: Chat ease of use: Focus on text input field when any text area is clicked; to put the cursor in the text areas instead of the input field, click there again.
• Remember the player checkboxes chosen in previous trade offer
• If new game options require a certain version, don't warn unless the required version is newer than 1.1.08 (released January 2010).
• Warn on server startup if robots take up most of maxConnections
• On server startup, show each property's description
• If the graphical PlayerClient starts a server, the "server is running" text on-screen now also says "Click for info" (D Sawyer idea)
• New debug command for robots: botname:print-vars
• If game is in progress, joining/leaving people also announced in chat area (less clutter there)
• Don't echo info commands like *STATS* to all players
• Bugfix: If observer closes the game window, shouldn't ask them if want to keep playing
• Bugfix: Truncating a long player name, don't drop the first character
• License upgrade to GPL v3

Updated 2011-01-22: (1.1.12)

• Don't show hovering road/settlement/city if player has no more pieces
• Feedback if 'Road Building' clicked but 0 roads left
• Lock/unlock button for robot seats: add tooltip, fix label when first shown
• Bugfix: Robot 'No thanks' displays after bank trade
• When 6-player board's window loses focus, un-expand the chat area
• If game has observers, list them when client joins
• For debugging, new "Free Placement" mode; see README.developer
• Further encapsulate board coordinate encoding

• 4-player board: crisper graphics (images from 6-player board)
• Practice games don't expire (Rowan H idea)
• Show rounds remaining for "roll no 7s during first n turns" (Rowan H idea)
• When moving robber and choosing a victim, popup shows their # VPs
• 6-player board: Always allow to request special build, even if no resources.
  Also allowed at start of own turn, only if not rolled or played card yet, and not when you are the first player taking your first turn.
• 6-player: During Special Building Phase, a player can ask to Special Build after the phase has begun, even if this means we temporarily go backwards in turn order. (Normal turn order resumes at the end of the SBP.) The board game does not allow this out-of-order building.
• 6-player robots: Slow down a little: Pause 75% of 4-player's pause duration, not 50%
• At end of game, show number of rounds along with resource stats and time elapsed
• Easier setup of other database types (besides MySQL)
• Robots can be automatically started when the server starts
• Other changes: see VERSIONS.txt
