Dominion Simple AI

A very simple ai/bot for Dominion

This is a simple ai/bot for the card game Dominion. It simply plays a "greens and golds" strategy, buying the most expensive money cards possible, or a province. In late game (>3 provinces already gained), it simply buys the most expensive victory point cards.

How to use

Older version

• Download this repo (or just the dominion_simple_ai.py file)
• Open Terminal, and cd to the directory with dominion_simple_ai.py
• Run python dominion_simple_ai.py

Newer version

• Run pip install git+https://github.com/https://github.com/danwiesenthal/dominion_simple_ai
• Run dominion_bot from the command line (anywhere)

This is designed to run on macOS (if you don't like that, you can modify the speak_str() function to not use the macOS say command for Text to Speech), and Python 3 (if you don't like that, please consider updating).

Example of output:

python dominion_simple_ai.py
