If you want to try the game, it's recommended to download and try the development branch first. The master branch should be stable, but is often out of date.

Windows Source

Requires Python 3.8+ and git. Install the latest version of Python 3 from here


git clone
cd Tuxemon
python -m pip install -U -r requirements.txt

Windows Binary

Check the release page for binaries.

Debian/Ubuntu with virtual environment

This is the recommended way to run because it will not modify the system.

sudo apt install git python3-venv
git clone
python3 -m venv venv
source venv/bin/activate
python3 -m pip install -U -r requirements.txt


Not recommended because it will change system-installed packages

sudo apt install python python-pygame python-pip python-imaging git
git clone
cd Tuxemon
sudo pip install -U -r requirements.txt

Debian/Ubuntu optional rumble support

sudo apt install build-essential
git clone
cd libShake/
make BACKEND=LINUX; sudo make install BACKEND=LINUX

Fedora Linux

sudo dnf install SDL*-devel freetype-devel libjpeg-devel portmidi-devel python3-devel virtualenv venv
python3 -m venv venv
source venv/bin/activate
python3 -m pip install -U -r requirements.txt

Arch Linux

Tuxemon is available in the AUR.


Android builds are highly experimental. Download and install the apk from the releases page and install to your device. You will need to manually install the mods folder. Connect your device to your computer and make a folder called "Tuxemon" in "Internal Storage", then copy the mods folder. Tuxemon will also need file system permissions, which you can set in your phones settings.

Mac OS X (Yosemite)

ruby -e "$(curl -fsSL"
brew tap Homebrew/python
brew update
brew install python
brew install sdl sdl_image sdl_ttf portmidi git
brew install sdl_mixer --with-libvorbis
sudo pip install git+
sudo pip install -U -r requirements.txt 
git clone
ulimit -n 10000; python


Game Controls
You can also set inputs in the options menu or config file
  • Arrow Keys - Movement
  • Enter - Select/activate
  • ESC - Menu/Cancel
  • Shift - Sprint

You can enable dev_tools by changing dev_tools to True in the tuxemon.cfg file:

dev_tools = True

These keyboard shortcuts are available with dev tools enabled

  • r - Reload the map tiles
  • n - No clip
Map Editor

Use Tiled map editor:

CLI Interface

The CLI interface is a very convenient way to debug and develop your maps. After you enable the CLI interface, you can use the terminal to enter commands. You could, for example, give your self potions to battle, or add a monster directly to your party. It's also possible to change game variables directly. In fact, any action or condition that is usable in the map can be used with the CLI interface.

Setting up

You can enable cli by changing cli_enabled to True in the tuxemon.cfg file:

cli_enabled = True


  • help [command_name] — Lists all commands, or specific information on a command.
  • action <action_name> [params] — Execute EventAction. Uses same syntax as the map script.
  • test <condition_name> [params] — Test EventCondition. Uses same systax as the map script.
  • random_encounter — Sets you in a wild tuxemon battle, similar to walking in tall grass.
  • trainer_battle <npc_slug> — Sets you in a trainer battle with specified npc.
  • quit — Quits the game.
  • whereami — Prints out the map filename
  • shell — Starts the Python shell, that you can use to modify the game directly. For advanced users.

CLI Examples

Get Commands

> help
Available Options
action  help  quit  random_encounter  shell  test  trainer_battle  whereami

Enter 'help [command]' for more info.

Get help on an action

> help action teleport

    Teleport the player to a particular map and tile coordinates.

    Script usage:
        .. code-block::

            teleport <map_name>,<x>,<y>

    Script parameters:
        map_name: Name of the map to teleport to.
        x: X coordinate of the map to teleport to.
        y: Y coordinate of the map to teleport to.

Test and give an item

> test has_item player,potion
> action add_item potion,1
> test has_item player,potion

NOTE! The CLI interface is new and the error messages are not very helpful. In general, you should be using the commands when the game is playing, and you are on the world map.

Check out the scripting reference for all the available actions and conditions for use with action and test!


There are many scripts for various builds in the buildconfig folder. These are meant to be run from the project root directory, for example, to build the portable pypy build:

[user@localhost Tuxemon]$ buildconfig/

There will be a new directory called build, which will have the package if everything was successful.

WARNING! The build scripts are designed to be run in a dedicated VM. They will add and remove packages and could leave your OS in a bad state. You should not use them on your personal computer. Use in a vm or container.
