GOP3 Blackjack Bot

This is a simple blackjack bot for the game "Governor of Poker 3".

It uses pyautogui to take screenshots and click buttons, and opencv to recognize the cards and buttons. Then it uses a strategy configuration cheatsheet to decide the next move. To self-define strategy, you can replace the const CHEAT_SHEET in constant.py. The self-defined strategy in GUI is on TODO.

The v2 tag is a quite stable version. From my several 10000 hand tests, the expectation is around 0.98. The main branch is for more features and improvements but the expectation will not change much.

Usage

1. Requirements in GOP3:
   • The game must be in fullscreen mode(1920*1080).
   • The game must be in English or Chinese(other language contributions are welcome!).
   • The game must be in the personal blackjack room.
2. Run the bot:

pip install -r requirements.txt
python main.py

TODO

• Add i18n support(supported languages: English, Chinese)
• Self-defined strategy in GUI
• Adapt different resolutions
• Better distinguish win/draw conditions
• Better splitting cards recognitions

Known issues

1. if this hand contains more than 5 cards, the bot will not recognize the cards correctly. That's because the cards begin to overlap, making recognition difficult.
2. the win/lose recognition is not right after splitting cards. After splitting cards, there are two win/lose hands on the table but the bot only recognizes one. So the behavior is (win, win) or (win, lose) detect a single win and (lose, lose) detect a single loss. This probably causes the net win to be about 10% higher than the actual net win from my tests.

Translation

This is a guide for translating the bot to other languages. If you want to contribute, please follow the steps below:

1. screenshot the game interface and save it to image/{language_name} folder. Required images are:
   • hit.png
   • stand.png
   • double.png
   • split.png
   • win.png
   • lose.png
   • draw.png
   • blackjack.png
   • bust.png
2. Add this language to the constants in main.py:

SUPPORTED_LANGUAGE = ["English", "Chinese"]
LANGUAGE_MAP = {
    "English": "en-us",
    "Chinese": "zh-cn",
}

you can see the image/zh-cn folder for reference.
