== Gameplay ==
=== What do I need to play, where can I go to play? ===
You will need to download then install free software.
=== OK, so I installed Freeciv. How do I play? ===
Start the client. Depending on your system, you might choose it from a menu, double-click on the freeciv-gtk3.22 executable program, or type freeciv-gtk3.22 in a terminal (to start the default "gtk3.22" client).
As your very first game, you may want to try the Tutorial scenario under .
To begin regular single-player game, select . Now edit your game settings (the defaults should be fine for a beginner-level single-player game) and press the button.
(Freeciv is a client/server system. But in most cases you don't have to worry about this; the client starts a server automatically for you when you start a new game.)
Once the game is started you can find information in its menu. If you've never played a Civilization-style game before you may want to look at the help on Strategy and Tactics.
You can continue to change the game settings through the menu item in the submenu of the menu. Type /help in the chatline (or server command line) to get more information about server commands.
Detailed explanations of how to play Freeciv are also in the file distributed with the source code, and in the in-game help.
=== How do I play multiplayer? ===
You can either join a network game run by someone else, host your own, or visit a web-server such as freecivweb.org.
To join a network game, choose and then . A list of active servers should come up; double-click one to join it. (The Freeciv project does not currently run any game servers, so any servers you find are likely to be run by third parties who have decided to advertise them.)
You can also choose to directly connect to a specific server (including ones not on the metaserver list), provided you know the IP address and port of the server you're connecting to. This server will then show up under Local Area Network.
To host your own game, we recommend starting a separate server by hand. (As of 2.4.0, it's no longer possible to host a network game from the client; in any case, we didn't recommend it, as if the client crashed or quit, the server and hence the game would be lost.)
To start the server, enter freeciv-server in a terminal or by double-clicking on the executable. This will start up a text-based interface.
If all players are on the same LAN, they should launch their clients, choose and then . You should see the existing server listed; double-click on it to join.
To play over the Internet, players will need to enter the hostname and port into their clients, so the host will need to tell the other players those details. You may also start up the server with the -m command-line option to make it report to the Metaserver and allow other players to connect to it through the tab.
Note that hosting an Internet server from a home Internet connection is often problematic, due to firewalling and NAT that can make the server unreachable from the wider Internet. The metaserver does not currently check that a server is reachable before publishing it, so unfortunately it is entirely possible to publish the existence of a game that no-one will be able to connect to. Safely bypassing NAT and firewalls is beyond the scope of this FAQ.
=== Where is the chatline you are talking about, how do I chat?===
The chatline is located at the bottom of the window. Sometimes you have to activate a tab to see it.
In the Gtk client, a shortcut to reach the chatline is the apostrophe () key. In the SDL client you have to press to access the chatline.
The chatline can be used for normal chatting, or for issuing server commands by typing a forward-slash '/' followed by the server command.
=== Why can't I attack another player's units? ===
You have to declare war first. See section for How do I declare war on another player below.
(As a note, you start out at war with all players; at lower skill levels, AI players offer you a cease-fire treaty upon first contact, which if accepted has to be broken before you can attack the player's units or cities.)
=== How do I declare war on another player? ===
Go to the Nations report, select the player, then choose from the bottom-located menu. This drops you from "cease fire", "armistice", or "peace" into "war". If you've already signed a permanent "alliance" treaty with the player, you will have to cancel treaties several times to get to "war".
See the in-game help on Diplomacy for more detail.
===How do I do diplomatic meetings?===
Go to the Nations report, select a player, then choose from the bottom-located menu. But remember that you have to either have contact with the player or an embassy established in one of their cities.
===How do I trade money with other players?===
If you want to make a monetary exchange, first initiate a diplomatic meeting as described in the section about How do I do diplomatic meetings above. In the diplomacy dialog, enter the amount you wish to give in the gold input field on your side or the amount you wish to receive in the gold input field on their side. With the focus in either input field, press to insert the clause into the treaty.
=== How can I change the way a Freeciv game is ended? ===
A standard Freeciv game ends when only allied players/teams are left alive, when a player's spaceship arrives at Alpha Centauri, or when you reach the ending turn - whichever comes first.
You can change the default ending turn by changing the endturn setting. You can do this through (see article on Server options) under the menu item in the menu or by typing into the chatline something like:
/set endturn 300
You can end a running game immediately with:
/endgame
For more information, try:
/help endgame
If you want to avoid the game ending by space race, or require a single player/team to win, you can change the victories setting - again either through the dialog or through the chatline. For instance this changes from the default setting spacerace|allied to disallow allied victory and space race:
/set victories ""
You can instead allow space races without them ending the game by instead changing the endspaceship setting.
A single player who defeats all enemies will always win the game -- this conquest victory condition cannot be changed.
In rulesets which support it, a cultural domination victory can be enabled, again with the victories setting.
=== My irrigated grassland produces only 2 food. Is this a bug? ===
No, it isn't. It's a feature. Your government is probably despotism, which has a -1 output whenever a tile produces more than 2 units of food/production/trade. You should change your government (see Government) to get rid of this penalty.
=== How do I play against computer players? ===
See also the How do I create teams of AI or human players? section below.
In most cases when you start a single-player game you can change the number of players, and their difficulty, directly through the spinbutton. Note the number of players here includes human players (an aifill of 5 adds AI players until the total number of players becomes 5).
If you are playing on a remote server, you'll have to do this manually. Change the aifill server option through the options dialog, or do it on the chatline with something like:
/set aifill 30
Difficulty levels are set with the /cheating, /hard, /normal, /easy, /novice, and /restricted commands.
You may also create AI players individually. For instance, to create one hard and one easy AI player, enter:
/create ai1
/hard ai1
/create ai2
/easy ai2
/list
More details are in the file supplied with Freeciv and the online manual on this site.
=== Can I build up the palace or throne room as in the commercial Civilization games? ===
No. This feature is not present in Freeciv, and will not be until someone draws the graphics for it.
=== Can I build land over sea/transform ocean to land? ===
Yes. You can do that by placing engineer units on a transport and going to the ocean tile you want to build land on (this must be in a land corner). Click the transport to display a list of the transported engineers and activate them. Then give them the order of transforming this tile to swamp. This will take a very long time though, so you'd better try with 6 engineers at a time. There must be 3 adjacent land tiles to the ocean tile you are transforming.
=== Can I change settings or rules to get different types of games? ===
Of course.
Before the game is started, you may change settings through the server options dialog (available in the pregame screen). You may also change these settings or use server commands through the chatline. If you use the chatline, use the
/show
command to display the most commonly-changed settings (see article on show), or
/help <setting>
to get help on a particular setting, or
/set <setting> <value>
to change a setting to a particular value (see article on server options). After the game begins you may still change some settings (but not others).
World maps can be created using the built-in map editor in the GTK clients. It is also possible to edit running games: Just enable from the menu. (You may also unzip and edit any savegame with a text editor, if you're ambitious, although the format is not documented and is subject to change.)
You can create rulesets or "modpacks" - alternative sets of units, buildings, and technologies. Several different rulesets come with the Freeciv distribution, including a civ1 (Civilization 1 compatibility mode), and civ2 (Civilization 2 compatibility mode). Use the rulesetdir command (see rulesetdir) to change the ruleset (as in /rulesetdir civ2). Note the ruleset mechanism is still being refined from version to version. In the GTK client you are able to choose the ruleset from a dropdown on the pregame screen.
Finally, upgrade! Freeciv continues to improve from version to version: a rule may change when the mailing list agrees it is 'wrong'. See, for instance, the NEWS.
=== How compatible is Freeciv with the commercial Civilization games? ===
Freeciv was created as a multiplayer version of Civilization™ with players moving simultaneously. Rules and elements of Civilization II, and features required for single-player use, such as AI players, were added later.
This is why Freeciv comes with several game configurations (rulesets): the civ1 and civ2 rulesets implement game rules, elements and features that bring it as close as possible to Civilization I and Civilization II respectively, while other rulesets such as the default civ2civ3 and older classic rulesets try to reflect the most popular settings among Freeciv players. Unimplemented Civilization I and II features are mainly those that would have little or no benefit in multiplayer mode, and nobody is working on closing this gap.
Little or no work is being done on implementing features from other similar games, such as SMAC, CTP or Civilization III.
So the goal of compatibility is mainly used as a limiting factor in development: when a new feature is added to Freeciv that makes gameplay different, it is generally implemented in such a way that the "traditional" behaviour remains available as an option. However, we're not aiming for absolute 100% compatibility; in particular, we're not aiming for bug-compatibility.
See also Projects.
=== My opponents seem to be able to play two moves at once! ===
Freeciv's multiplayer facilities are asynchronous: during a turn, moves from connected clients are processed in the order they are received. Server managed movement is executed in between turns. This allows human players to surprise their opponents by clever use of goto or quick fingers.
Server settings to mitigate this problem include:
* phasemode, which has an alternating movement mode, in which only one player can move their units at a time.
* timeaddenemymove (which extends the turn timeout when an enemy's unit is seen moving).
* (since 2.3.x) unitwaittime (which imposes a minimum time between moves of a single unit on successive turns).
=== I am far superior to my opponent but their last city is on a 1x1 island so I cannot conquer it, and they won't give up. What can I do? ===
Research 'amphibious warfare', build a marine, and get them. Alternatively research 'combined arms' and either move a helicopter or airdrop a paratroopers unit there.
If you can't build marines yet, but you do have engineers, and other land is close-by, you can also build a land-bridge to the island (i.e. transform the ocean).
=== Why are the AI players so hard on 'novice' or 'easy'? ===
You are not expanding fast enough. Read the How to Play article for some general tips how to get a head start in the game.
You can also turn off Fog of War. That way, you will see the attacks of the AI. Just type '/set fogofwar disabled' on the chat line before the game starts.
=== Why are the AI players so easy on 'hard'? ===
Several reasons. For example, the AI is heavily playtested under and customized to the default ruleset and server settings. Although there are several provisions in the code to adapt to changing rules, playing under different conditions is quite a handicap for it. Though mostly the AI simply doesn't have a good, all encompassing strategy besides "eliminate nation x". For further details, see the article on AI.
To make the game harder, you could try putting some or all of the AI into a team. This will ensure that they will waste no time and resources negotiating with each other and spend them trying to eliminate you. They will also help each other by trading techs. See the question How do I create teams of AI or human players?
You can also form more than one AI team by using any of the different predefined teams, or put some AI players teamed with you.
=== What distinguishes AI players from humans? What do the skill levels mean? ===
AI players in Freeciv operate in the server, partly before all clients move, partly afterwards. Unlike the clients, they can in principle observe the full state of the game, including everything about other players, although most levels deliberately restrict what they look at to some extent.
All AI players can change production without penalty. Some levels (generally the harder ones) get other exceptions from game rules; conversely, easier levels get some penalties, and deliberately play less well in some regards.
For more details about how the skill levels differ from each other, see the help for the relevant server command (for instance /help hard).
Other than as noted here, the AI players are not known to cheat.
=== How do I play on a rectangular grid? ===
It is possible to play with rectangular instead of hexagonal tiles. To do this you need to set your topology before the game starts; set this with Map topology index from the game settings, or in the chatline:
/set topology iso|wrapx
/\
| |
\/
This will cause the client to use an isometric rectangular tileset when the game starts (go to Game > Options >Local options to choose a different one from the drop-down; amplio2, cimpletoon, and isotrident are included with the game).
_
/ \
\_/
You may also play with overhead rectangular, in which case you want to set the topology setting to 'wrapx'; the trident tileset is supplied for this mode.
=== How do I create teams of AI or human players? ===
The GTK and Qt clients have a GUI for setting up teams - just right click on any player and assign them to any team.
You may also use the command-line interface (through the chatline.)
First of all try the /list command. This will show you all players created, including human players and AI players (both created automatically by aifill or manually with /create).
Now, you're ready to assign players to teams. To do this you use the team command. For example, if there's one human player and you want two more AI players on the same team, to create two AI players and put them on the same team you can do
/set aifill 2
/team AI*2 1
/team AI*3 1
You may also assign teams for human players, of course. If in doubt use the /list command again; it will show you the name of the team each player is on. Make sure you double-check the teams before starting the game; you can't change teams after the game has started.
=== I want more action. ===
In Freeciv, expansion is everything, even more so than in the single-player commercial Civilization games. Some players find it very tedious to build on an empire for hours and hours without even meeting an enemy.
There are various techniques to speed up the game. The best idea is to reduce the time and space allowed for expansion as much as possible. One idea for multiplayer mode is to add AI players: they reduce the space per player further, and you can toy around with them early on without other humans being aware of it. This only works after you can beat the AI, of course.
Another idea is to create starting situations in which the players are already fully developed. There is no automated support for this yet, but you can create populated maps with the built-in editor.
=== I can't see trade routes in the city dialog (GTK+) ===
In the GTK client, you can see the effect of trade routes by left clicking and holding on the trade value in the Info panel of the city dialog.
== Community ==
=== Does Freeciv violate any rights of the makers of Civilization I or II? ===
There have been debates on this in the past and the honest answer seems to be: We don't know.
Freeciv doesn't contain any actual material from the commercial Civilization games. (The Freeciv maintainers have always been very strict in ensuring that materials contributed to the Freeciv distribution or website do not violate anyone's copyright.) The name of Freeciv is probably not a trademark infringement. The user interface is similar, but with many (deliberate) differences. The game itself can be configured to be practically identical to Civilization I or II, so if the rules of a game are patentable, and those of the said games are patented, then Freeciv may infringe on that patent, but we don't believe this to be the case.
Incidentally, there are good reasons to assume that Freeciv doesn't harm the sales of any of the commercial Civilization games in any way.
=== How do I wake up in the morning? ===
We're open to suggestions on this one.
You can try to give Freeciv to your boss. There is no guarantee, but they may wake up later than you.
Remind yourself that if you run into them at Civilization Anonymous, it's time to change jobs.
=== Where can I ask questions or send improvements? ===
Please ask questions about the game, its installation, or the rest of this site at the Freeciv Forums.
Patches and bug reports are best reported to the Freeciv bug tracking system at https://redmine.freeciv.org/projects/freeciv.
== Technical Stuff ==
=== I've found a bug, what should I do? ===
See the article on Bug Reporting.
=== I've started a server but the client cannot find it! ===
By default, your server will be available on host localhost (your own machine), port 5556; these are the default values your client uses when asking which game you want to connect to.
So if you don't get a connection with these values, your server isn't running, or you used -p to start it on a different port, or your system's network configuration is broken.
To start your local server, run freeciv-server. Then type start at the server prompt to begin!
mike@localhost:/usr/local/bin$ ./freeciv-server
This is the server for Freeciv version 3.0.3

Starting game.
If the server is not running, you will NOT be able to connect to your local server.
If you can't connect to any of the other games listed, e.g. those on the metaserver, a firewall in your organization/ISP is probably blocking the connection.
If you are running a personal firewall, make sure that you allow communication for freeciv-server and the Freeciv client to the trusted zone. If you want to allow others to play on your server, allow freeciv-server to act as a server on the Internet zone.
=== I can play on my own server, but the metaserver doesn't seem to work. ===
If your tab turns up an empty list, there might something wrong with your setup.
First, check your Freeciv version. Freeciv clients can only talk to servers of the same major version (3.1.x can only talk to 3.1.y), and there may simply be no public servers for the version you're running. Check out the web interface (which shows servers for all versions) and look at the "version" column.
If you can view the metaserver page with your web browser, and servers are listed, but the client's tab still fails to list them, you may be behind a non-transparent proxy. See article on proxy settings for a detailed explanation.
Another possibility is that your freeciv build lacks access to certificates needed to access https -sites. You can test if that's the case by trying to use "http://meta.freeciv.org/metaserver.php" as the metaserver URL instead of the default one. You can either give the alternative URL by command line parameter "-M http://meta.freeciv.org/metaserver.php" for single run, or permanently in the client settings.
=== How do I change the metaserver info string? ===
Set the metamessage setting. See /explain metamessage.
> set metamessage "Everybody Welcome!"
=== Am I using the latest version? Do I need to upgrade? ===
The current stable Freeciv version is . For an overview of changes that went into this release,
see the NEWS- article.
The NEWS-#.#.# article is only updated for a new release; updates to Git can be reviewed in the online source code browser.
If you decide to upgrade, see the Download page for source code or contributed binaries. If you have a working client, and you don't know its version, start it, load a game or scenario, or just start a new game, click on for the help menu, and on to see the version and the client type (GTK3.22, GTK4, QT, SDL2, …).
It's possible that not all precompiled binaries and ports have been updated to yet. If you can contribute, please do! Prepare a package and announce it to freeciv-dev@freelists.org.
Clients and servers of different major versions are generally incompatible due to changes in the client/server protocol. You will see incompatibilities as a 'mismatched capabilities' error. Different minor versions should be compatible, however. For example, 3.1.2 and 3.1.0 are compatible; 2.6.6 and are not.
=== "cannot open display :0" ===
The Freeciv client is unable to open a window on your local X display. Are you running an X server at all? Maybe you need to install and run one, or switch to a Freeciv client that doesn't need X; see the previous question.
Under Mac OS X, try starting the Freeciv client from the xterm session running under X.
=== HOME directory not set? ===
The Freeciv client wants to write a configuration file named freeciv-client-rc-3.1 (for Freeciv 3.1.x) in a directory called .freeciv in your $HOME directory. On Windows that's %APPDATA%. So for instance for Freeciv 3.1 the Windows clients might put their common configuration file in C:\Users\username\AppData\Roaming\.freeciv\freeciv-client-rc-3.1.
=== How do I restart a saved game? ===
If for some reason you can't use the start-screen interface for loading a game, you can load one directly through the client or server command line (see Command-line options). You can start a client such as freeciv-gtk3.22, or freeciv-server, with the -f option, for example:
freeciv-server -f freeciv-T0175-Y01250-auto.sav.xz
Or you can use the /load command inside the server before starting the game.
=== The server cannot save games! ===
In a local game started from the client, the games will be saved into the default Freeciv save directory (typically ~/.freeciv/saves/). If you are running the server from the command line, however, any savegames will be stored in the current directory. If the autosaves server setting is set appropriately, the server will periodically save the game automatically (which can take a lot of disk space in some cases); the frequency is controlled by the saveturns setting. In any case, you should check the ownership, permissions, and disk space/quota for the directory or partition you're trying to save to.
=== Where are the save games located by default? ===
On Unix like systems, they will be in ~/.freeciv/saves.
On Windows, they are typically found in a directory like C:\Users\username\AppData\Roaming\.freeciv\saves.
On MacOS systems, it's "/Users/{username}/.freeciv/saves", but the finder won't show you folders that start with ".". You can toggle that by entering CMD+Shift+. while in a finder window. While the hidden stuff is visible you can create an alias to the ".freeciv" folder which will always be visible.
You could change the save games location by using the --saves command line argument to the server (you would have to run it separately).
=== How do I find out about the available units, improvements, terrain types, and technologies? ===
There is extensive help on this in the menu, but only once the game has been started - this is because all of these things are configurable up to that point. (Some work needs to be done to make this more intuitive.)
The game comes with an interactive tutorial scenario. To run it, select from the main menu, then load the tutorial scenario.
Outside the Freeciv client, we have some online tutorials in the Docs section of the wiki. A graph of the (default) technology tree is available on the wiki.
=== I hate isometric view! How do I play with Civilization I style graphics? ===
When starting the game, go to > > , and make sure Isometric is not checked.
The overhead tileset trident is supplied for this topology.
=== What other GUI options do I have for the Freeciv client? ===
The look and feel of your GUI is mainly determined by the Freeciv client you use.
The recommended client is the Gtk client. There are a range of different Gtk clients for different versions of the Gtk library—Gtk3/3.22/4/etc—but they all support more or less the same feature set. If in doubt, pick the Gtk3.22 client.
The Qt client is a newer client using the Qt toolkit. It has a more immersive interface. It supports most features, with the notable exception of the map editor.
The SDL2 client provide a more immersive experience, but lags behind somewhat in features.
All of these clients should compile and run on any Unix variant we are aware of, not just the ones for which our download section provides native installation support.
For Windows, the Gtk and Qt clients are recommended.
Some details of the GUI can be configured from the running client.
A larger impact is made by the tileset used to display terrain, cities, units, etcetera. Freeciv comes with some tilesets for all topologies; some more can be acquired with the freeciv-modpack utility.
We do not distribute commercial Civilization™ game tiles for obvious copyright reasons.
=== How do I enable/disable sound support? ===
The client can be started without sound by supplying the commandline arguments: -P none. The default sound plugin can also be configured in the client settings.
If the client was compiled with sound support, it will be enabled by default. (The only sound plugin supported currently is sdl.)
Further instructions are in ./doc/README.sound in the source tarball.
If sound does not work, try:
freeciv-gtk3.22 -d verbose -P <plugin> -S stdsounds
This will help you get some debug information, which might give a clue why the sound does not work.
=== Where can I find more information on the *.ruleset files? ===
There is some documentation in the ./doc/ directory, such as ./doc/README.effects. The supplied ruleset files also have a minimal explanation of what all the fields mean, so classic/buildings.ruleset would for instance list the meaning of the fields in the buildings.ruleset. Also of interest might be the rulesets page on freeciv.org.
=== How can I add additional civilizations to be used locally? ===
See README.nations in the documentation directory, chapter labeled Local Nation files
=== How can I add additional civilizations in the nation/ subdirectory of freeciv installation, or add cities to the list for an existing nation? ===
See the Nations article or ./doc/README.nations in the source tarball.
=== How can I change the language of my client/server? ===
See the Interface Language wiki article.
=== How do I get the latest development code? ===
Use Git directly:
# Obtain and install Git on your Unix machine. On modern distributions it is already there; look for the git command. You can get Git from git-scm.com.
#Grab the source:
#:$ git clone https://github.com/freeciv/freeciv
Once you're retrieved the source, to update it, cd into
the freeciv directory and issue git pull.
Another useful git command is git diff.
This shows the changes between the version you have on disk and the current development code.
This is development code; it may contain new features, bugs, and incompatibilities with older versions.
See also How to Contribute to Freeciv development.
=== What are the system requirements? ===
;Memory:
In a typical game the server takes about 30MB of memory and the client needs about 200MB. These values may change with larger maps or tilesets. For a single player game you need to run both the client and the server.
;Processor:
We recommend at least a 200MHz processor. The server is almost entirely single-threaded, so more cores will not help. If you find your game running too slow, these may be the reasons:
:; Too little memory
:: Swapping memory pages on disc (virtual memory) is really slow. Look at the memory requirements above.
:; Large map
:: Larger map doesn't necessary mean a more challenging or enjoyable game. You may try a smaller map.
:; Many AI players
:: Again, having more players doesn't necessary mean a more challenging or enjoyable game.
:; City Governor (CMA)
:: This is a really useful client side agent which helps you to organize our citizens. However, it consumes many CPU cycles.
:; Maps and compression
:: Creating map images and/or the compression of saved games for each turn will slow down new turns. Consider using no compression.
;Graphic display:
The GTK client works well on 1024x800 or higher resolutions. On smaller screens you may want to enable the Arrange widgets for small displays option under tab in local options.
;Network:
A 56Kb modem should be enough to play a typical online game. However, many players suggest that a large ping is a big disadvantage. Your ISP mustn't block ports 5556 - 5600, because these are the ports which typical servers are run on.
== Windows ==
=== How do I use Freeciv under MS Windows? ===
Precompiled binaries can be downloaded from www.freeciv.org. The native Windows packages come as self-extracting installers.
Simply download and install one of the .EXE installers (GTK+-3.22, GTK-4, SDL2, Qt, or Ruledit). As of freeciv-3.1, there are "win64-10" packages that require Windows 10 or later, and "win64" packages that require just Windows 8.1 or later. As Qt6 itself requires Windows 10, "win64" versions of Qt-client and Ruledit are based on Qt5 and only "win64-10" versions are based on Qt6.
=== OK, I've downloaded and installed it, how do I run it? ===
If you used one of the self installer versions then there's a program group with the name chosen at installation time (for example, Freeciv  (GTK+3.22 client).) Just go to click on Start→Programs→Freeciv  (GTK+3.22 client)→Freeciv
That's it! You should be up and running.
=== I've started the Freeciv client, but don't know what to do next? ===
The following steps should get you started:
# The Freeciv client will pop up and after a second you will be taken to the main menu.
# If you want to play against other humans (I think they're human anyway :-) then click on the button in the main menu. Then either type in the IP address of the server or select the Internet Metaserver tab to play on online public servers. Then select an available game and click the button. (You may need to click the button to get the list of servers initially and to update it after a while.)
# If you want to play on your local machine against the AI (all other players are AI controlled) then click on the button. Then select your difficulty level and the Total players (it includes yourself, so if you wanted to play against four AI players, you'd select 5).

=== How do I use a different tileset? ===
If the tilesets supplied with Freeciv don't do it for you, some popular add-on tilesets are available through the "Freeciv Modpack Installer" utility. To install these, just launch the installer from the Start menu, and choose the one you want; it should then be automatically downloaded and made available for the current user.
If the tileset you want is not available via the modpack installer, you'll have to install it by hand from somewhere.
Then you have to unpack the tileset into the appropriate place. It's best to install it in your user directory. Locate the existing client settings file freeciv-client-rc-3.1; see the question HOME directory not set? to see where that might be. You want to put the tileset in a subdirectory named after the current version (e.g., 3.1\) in the same place as the client settings file. Usually, the main tilespec file foo.tilespec goes directly under 3.1\, and the rest of the tileset files will go in a subdirectory named after the tileset (e.g., 3.1\foo).
You can alternatively unpack the tileset into the same data directory as the rest of your Freeciv installation, alongside the supplied .tilespec files, but that can lead to trouble with uninstallation or upgrades.
Once the tileset is installed, you should be able to select it in the topology-specific tileset dropdowns in the client options. You will need to make sure your game uses the appropriate map topology for the tileset in the game options.
You can also pass a command-line argument to the Freeciv client when you start it to force use of a specific tileset. This also requires that the tileset has been installed in a correct place. Open a Command Prompt, find the client executable, and start the client with the --tiles tilesetname option. For example for the gtk3.22 client, you might start
freeciv-gtk3.22 --tiles hexemplio
=== How do I use a different ruleset? ===
Again, this is easiest if the ruleset is available through the "Freeciv Modpack Installer" utility that's shipped with Freeciv.
Otherwise, a different ruleset can be used by downloading the ruleset and extracting it in the same place as you would a tileset (see previous question). Generally, the .ruleset and .lua files go in a subdirectory named after the ruleset (for instance ancients\*.ruleset; if there is a .serv file it generally goes directly in the 3.1\ directory.
Then you need to tell Freeciv to use it. For single-player games, if there is a .serv file, the ruleset should be available to select from the drop-down in the client. Otherwise, you can load a ruleset which has a foo.serv file with
/read foo
from the client chatline or server command line before starting the game; you can read a ruleset without a .serv file by typing
/rulesetdir ruleset directory
=== I opened a ruleset file in Notepad and it is very hard to read ===
The ruleset files (and other configuration files) are stored with UNIX line endings which Notepad doesn't handle correctly. Please use an alternative editor like WordPad, notepad2, or notepad++ instead.
==Mac OS X==
As of 3.1, a zip file with a real Mac application "freeciv.app" is available on the download page. Requires MacOS 11.x or later (Big Sur or Monterey).
For earlier versions of MacOS, there are unofficial installer packages available, see the Install-MacOSX page on the Freeciv wiki for links and more information.
