Dataset Overview

This dataset contains real human gameplay from Arkadium's gin rummy platform, providing researchers and developers with high-quality training data for game AI, reinforcement learning, and computer vision applications. All hands include screenshots.

RAW data only. The primary dataset is a single raw ZIP archive (.pbn/.webp). Parquet files in data/ contain only 10 example records for the HuggingFace Dataset Viewer and are not a full export. We do not provide a full Parquet version.

Totals (selected subset): 10,000 matches, 686,403 screenshots, ~23.62 GB compressed ZIP size. The dataset is capped at 10,000 unique hands with screenshots and packaged into a single archive.

Metric	gamelogs_with_images
Raw match logs	10,000
Raw screenshots	686,403
Raw ZIP size	~23.62 GB
Raw format	PBN + WebP (ZIP)

Use Cases

• Game AI Training: Train models to predict optimal draws/discards using supervised learning on human gameplay.
• Reinforcement Learning: Use as demonstration data for imitation learning or to initialize RL agents.
• Computer Vision: Card/board state recognition, meld detection, and UI state extraction from images.
• Strategy Analysis: Study human decision-making patterns, draw/knock timing, and deadwood management.

Parquet Preview (10 records)

Parquet files in `data/` are **only a 10-record preview** for the HuggingFace Dataset Viewer. They exist **exclusively for demo/browsing** and **do not represent the full dataset**. All primary data is in the raw ZIP archives above, and no full Parquet release is provided.

Quick Start (Preview)

Installation

pip install datasets pillow

Load the Preview

from datasets import load_dataset

# Load preview with screenshots (10 records)
ds = load_dataset("ArkadiumInc/ArkadiumGinrummy", "gamelogs_with_images")

Basic Usage

# Access a single hand
hand = ds["train"][0]

print(f"Players: {hand['player1']} vs {hand['player2']}")
print(f"Date: {hand['event_date']}")
print(f"Score: {hand['score']}")
print(f"\nMoves:\n{hand['moves']}")

Working with Screenshots

from PIL import Image
import io

# Get a hand with images
hand = ds["train"][0]

print(f"This hand has {hand['num_images']} screenshots")

# Display the first screenshot
if hand['images']:
    img = Image.open(io.BytesIO(hand['images'][0]))
    img.show()
