[Tests coverage]

Bot was tested with Python 3.7+ and PyPy3, we are not supporting Python 2.

Mahjong bot

For research purposes we built a simple bot to play riichi mahjong on tenhou.net server.

Here you can read about bot played games statistic: versions history

For developers

How to run it?

1. pip install -r requirements/lint.txt
2. Run cd project && python main.py it will connect to the tenhou.net and will play a game.

How to run bot battle with pypy

To make it easier run bot vs bot battles we prepared PyPy3 Docker container.

Run the game locally:

1. Install Docker
2. Run make build_docker
3. Run make GAMES=1 run_battle it will play one game locally. Logs and replays will be stored in bots_battle folder.

Run bots with enabled decision logger (use it only for debug, since it harms performance):

1. Run make GAMES=1 ARGS=--logs run_battle

Run multiple bots to play one game

1. Install Docker and Install Docker Compose
2. Run make build_docker
3. Put bot configs to project/settings/. By default we are looking for these configs: bot_1_settings.py, bot_2_settings.py, bot_3_settings.py, bot_4_settings.py, bot_5_settings.py. Why 5 settings? Because tenhou doesn't start 2+ game in the custom lobby if you are running only 4 bots.
4. Run make run_on_tenhou

Configuration instructions

1. Put your own settings to the project/settings/settings_local.py file. They will override settings from default settings/base.py file.
2. Also, you can override some default settings with command arguments. Use python main.py -h to check all available commands.

It can be useful to debug bot errors or strange discards: game reproducer
